HISTORY & DUTIES 

of the 

MONTANA LIVESTOCK SANITARY BOARD 



The Livestock Sanitary Board was created by Chapter 152 of the 1907 
Laws of Montana and re-enacted by Chapter 262 of the 1921 Laws of 
Montana. 

The duties of the Livestock Sanitary Board are set out in Sections 
46-208 through 46-246; 46-301 through 46-303; 46-401 through 46-415; 
46-907; 46-2401 through 46-2406; 46-2501 through 46-2515 and 46-2601 
through 46-2611, R.CM, 1947. 

It is the duty of the Livestock Sanitary Board to confine, 
eradicate, control or prevent diseases of livestock and 
poultry; to prevent the introduction of livestock and poultry 
diseases into the State of Montana; to maintain a Diagnostic 
Laboratory; to license and to establish and maintain a system 
of inspection of meat and meat plants, slaughterhouses, 
dairies, milk and milk plants, rendering plants, garbage- 
feeding and garbage cooking establishments and animal arti- 
ficial insemination. In addition, it is the duty of the 
Livestock Sanitary Board to obtain samples of meat and milk 
offered for human consumption and carry out bacteriological 
and chemical analyses of these samples; to provide for safety 
of manufactured or refined foods for livestock; and to pro- 
vide for the control and safety of remedies and biological 
products used for treatment of animals. 



ADMINISTRATION D I V 1 S ION REPORT PAGE 1 



SUMMARY OF PURPO SE AMD OB JECTIVES 

Montana, with its nearly 3,000,000 cattle, 1,600,000 sheep, 200,000 swine, 
2,000,000 poultry, 100,000 horses and other animals, contributes much to providing 
precious food and fiber to a nation with a rapidly expanding population. The com- 
bined livestock and poultry industries, with their dependent allied industries, 
are essential to the economic stability of our state. During this recent era of 
food surpluses, which appears to be coming rapidly to a close, too many have had 
a tendency to take our blessings of adequate, wholesome food and fiber and a 
healthy, prosperous livestock and poultry industry for granted. The Montana Live- 
stock Sanitary Board and its staff, whose assigned duty and responsibility it is 
to safequard the heaiith of this extremely important industry, do not take this 
for granted; 

They know, all too well, that livestock diseases can, if permitted, decimate a 
livestock and poultry industry, They know that starvation, economic misery and 
political unrest in many countries today is the result of failing to recognize a 
healthy livestock population as the foundation of socio-economic stability. It 
has been the purpose of the Livestock Sanitary Board staff and Montana veterinari- 
ans, all of whom carry Deputy State Veterinarian appointments, to carry out every 
safeguard possible to protect the livestock and poultry industry from disease and 
to assure many people continued, adequate amounts of safe, wholesome food and 
fiber. To this, they are dedicated. It is hoped this Annual Report wi 1 1 properly 
reflect their combined efforts to accomplish these important objectives. 



LIVESTOCK SAN ITARY BOARD STAFF 

The demand of government and industry for veterinary medical scientists continues 
to increase. The 18 Colleges of Veterinary Medicine have not been able, and will 
not be able In the foreseeable future, to graduate sufficient numbers of veterin- 
ary medical scientists to meet this demand, 

It is most difficult for the Montana Livestock Sanitary Board to attract and main- 
tain the scientific, professional staff it must have in order to provide adequate 
safeguards for a healthy livestock industry and assure a safe product to Montana 
meat and milk consumers, when professional salaries are at least i5% to 30% lower 
than those offered by competing government agsncies, industry and private practice. 
The result has been that key positions have been vacant on the staff somewhere 
in the organization for 10 years. At the close of the fiscal year, two District 
Deputy State Veterinarian positions and one Veterinary Meat Inspector position 
were vacant. With only 6 District Deputy State Veterinarian positions on the 
entire state field-staff, vacancy of I '3 of these positions is dangerous. The 
organizational structure of the Livestock Sanitary Board is established and main- 
tained to have a minimum of trained, competent District Deputy State Veterinarians 
capable - at a moments notice - to recognize and establish emergency disease con- 
trol measures. This Is an absolute essential to the safety of the industry. The 
inability to attract competent veterinarians to a career in state public service, 
resulting in a reduction by 1/3 of a minimum staff, is a risk the industry and 
Montana should not have to take. This same situation exists with scientific per- 
sonnel required in the laboratory , in meat inspection and in milk inspection work. 



Administration Division Report PAGE 2 



Montana's livestock industry and food- producing capabilities are too precious to 
the state and nation to risk by not having the safeguard of competent veterinary 
medical scientists readily available on the Montana Livestock Sanitary Board 
staff. 

The valuable work that has been accomplished has been done by a dedicated few who 
have tried very hard to do their own work and also carry the additional load 
created by vacancies on the staff. They simply would not be abie to stretch 
their dedication and willingness to work, should we be faced with only a "small" 
emergency disease outbreak which can happen at any time. 

The accomplishments of these dedicated men and women this past fiscal year are 
presented to the Montana Livestock Sanitary Board with most sincere gratitude. 



Pi AGNOSTIC LABORATORY DIVISION 

The Diagnostic Laboratory and its work is essential to the operation of all Divi- 
sions in the Livestock Sanitary Board. The Disease Control Division could not 
carry out its functions without the assistance of accurate laboratory findings. 
The Milk and Dairy Inspection Division could not assure the people of Montana a 
safe, wholesome fluid-milk supply without the assistance of thousands of routine 
mflk tests. The Meat Inspection Division could not assure the people of Montana 
a safe, wholescme meat supply without laboratory assistance in the diagnosis of 
livestock diseases and the testing of meat products to determine their labeled 
content. 

Modern technological advances require that a laboratory have proper equipment, 
facilities and a properly trained staff. The Livestock Sanitary Board is to be 
commended for their efforts to maintain as good a state diagnostic laboratory as 
can be found anywhere. 

The review of the livestock diseases present in Montana emphasizes the great need 
for tmproving the capability of the laboratory in the diagnosis of virus diseases. 
It is recommended that additional personnel, trained in virus diagnostic tech- 
niques, be added to the staff and the necessary laboratory equipment be obtained 
to meet this important demand. 

In 1965 the Montana Horse Racing Commission requested the Montana Livestock Sani- 
tary Board to determine if the Diagnostic Laboratory could run drug-detection 
tests on race horses, thus avoiding to have the tests made In an out-of-state 
laboratory. Due to the lack of some laboratory equipment and personnel trained 
to perform the tests, the Board determined that the laboratory was unable to per- 
form the tests in the IS65/66 racing season. Trained personnel were available the 
following year and necessary equipment was obtained. The chemistry laboratory 
section of the Diagnostic Laboratory started to perform the tests in June, 1 966. 
The Montana Horse Racing Commission arranged payment for the running of the tests 
from the race tracks submitting the samples. The cost of the equipment and running 
of the tests will be amortized from the fees charged. This not only assists 
another state agency, by using an available laborator/ in Montana, but provides 
equipment that increases the capability of the laboratory to make toxicological 
examinations. It also helps provide an additional chemist who will be needed to 



Administration Dlvis ion Report PAGE 3 



perform the required gas chromatography analyses of meat and milk. Capital item 
funds became available at the end of the fiscal year to purchase the required gas 
chromatograph to detect pesticides in meat and milk. 

A review of the work performed by the Diagnostic Laboratory Division reveals ever- 
increasing demands for their exacting scientific work. There is every indication 
that these demands will continue to increase. 



DISEASE CONTROL DIVISION 

The reports of the Diagnostic Laboratory Division, the Disease Control Division 
and the Meat Inspection Division combined will reflect the over-all animal dis- 
ease picture in Montana for the fiscal year. An analysis of the livestock and 
poultry disease reports indicates that the health of Montana livestock has never 
been better. There was an absence, during the fiscal year, of outbreaks of such 
diseases as anthrax, bluetongue, hog cholera, Newcastle disease and scabies which 
have, in the past, required extraordinary control procedures. Previous costly 
diseases, such as brucellosis, tuberculosis and pullorum are at a very low level. 

Even though the livestock health record is good, there is always the "smoke and 
flames" of diseases that must be suppressed before they become conflagrations. In 
addition to the detailed reports of livestock diseases contained elsewhere in this 
report, it is believed the following diseases merit the continued attention of the 
Livestock Sanitary Board 

Brucel losis 

Progress was made during the fiscal year to eradicate brucellosis. More cattle 
were tested at slaughter, through continued Improvement of the market-cattle- 
testing program which is proving to be a tremendous asset in county recertifi- 
cation and early detection of newly infected herds. Cattle infection rate of 
0.311% and herd infection rate of 0.11°% at the end of the fiscal year were the 
lowest ever recorded. Thirty-eight counties, at the end of the fiscal year, had 
no known infected herds - an increase of one county. No case of human brucellosis 
was reported. 

Even though progress has been made, many problems arise in attempts to effect 
final eradication. The greatest problem Is general apathy. As a disease that 
once caused great economic loss and public health danger is reduced to a point 
where there is no over-all economic loss or public health danger, then the stimu- 
lus to persist in efforts for final eradication is greatly reduced. This must 
not happen. If the last persistent effort is not made, there is sufficient foci 
of infection remaining to reestablish brucellosis. 

Encephal it is 

The number of cases of Western Equine Encephalitis in August and September of 
1965 was the highest recorded since the pandemic in 1938, This indicated a simi- 
larity of increase of incidence which preceded the 1933 pandemic. Increased mos- 
quito activity in IS65 and a susceptible horse population were probably two 
factors contributing to the outbreak. 



Administration Division Report PAGE k 



Every effort was made to encourage horse owners to vaccinate their horses prior to 
the 1966 season and to carry out mosquito control in and around poultry premises. 

It would appear that response to these efforts has been good, leading us to be- 
lieve there will not be a repetition of the number of cases in 1 966 as occurred 
in 1965. 

Epididym? t is 

It was definitely established during the fiscal year that ram epididymitis Is 
widespread in Montana and is causing quite serious economic loss in flocks having 
the disease. 

In December, 1 965 a committee of the Montana Woolgrowers Association met with the 
Livestock Sanitary Board to explore ways and means to control the disease. Fol- 
lowing the meeting, members of the Livestock Sanitary Board and Montana Veterin- 
ary Research Laboratory staff assembled all available information on ram epididy- 
mitis for review with the Montana Woolgrowers committee. As the result of this 
study, the Montana Livestock Sanitary Board, in March, 1966, adopted regulations 
to provide for official vaccination of rams with REO bacterln and revised Regu- 
lation 1521, requiring specific clinical examination for ram epididymitis of rams 
to be Imported into Montana. They also made recommendations for vaccination of 
breeding rams and recommendations for inspection and rejection of rams with epi- 
didymitis being offered for sale at public markets. 

It Is recommended that the Board, with the cooperation of the Montana Woolgrowers 
Association, continue to observe and study ram epididymitis in order to Implement 
any action which will become necessary to assist in the control of this disease. 

Fluorosis 

Again this fiscal year, reports were received of cattle showing clinical signs of 
fluorosis. Again, all cases were located within a 15 mile radius of Garrison. 

It seems strange, in this era of technological advancement, that an industry would 
continue to throw out materials Into the environment which affects the health of 
animals of the most basic and important industry in our state. It is recommended 
that the Livestock Sanitary Board continue its efforts to seek appropriate mea- 
sures that would prevent the indiscriminate discharge of poisons. This can be 
done in such a way that both industries couid exist side by side. 

Hog Cholera 

Culminating about kO years of effort, hog cholera has been eradicated from Mon- 
tana. This fact was recognized In February, 1 966, by the presentation to Governor 
Babcock from the United States Department of Agriculture of a plaque declaring 
Montana a hog cholera-free state. Being free of hog cholera will mean much to 
Montana swine producers. It will be a little additional measure to assist in pro- 
viding adequate food to an expanding population. 

It will be most worthwhile to maintain this freedom from hog cholera. It is rec- 
commended that continued all-out efforts be made to prevent a refntroduction. It 
is recommended that should hog cholera reappear in Montana, immediate action be 



Administration Division Report page 5 



talon to confine the disease and properly dispose of all infected and exposed 
swine. This should be followed by careful, supervised cleaning and disinfection 
of premises and contaminated equipment before restocking. To effect such pro- 
cedure, it Is recommended that funds always be available to indemnify owners of 
swine that are ordered destroyed. Such action will assure continued freedom from 
hog cholera. 

Rabies 

This dreadful disease, during the fiscal year, posed a very real threat to live- 
stock and human health. The disease has made its entry into Montana in the skunk 
population in eastern Montana. It is apparent that skunk rabies has been gradu- 
ally spreading westward over a number of years. 

Fifteen laboratory-confirmed rabid skunks from December, 1965 through May, 1966 
established the seriousness of the threat. 

It seems inconceivable that Montana, for the first time in history, should have 
to live in fear of rabies endemic In its animal population. Definite steps were 
taken to establish an all-out-effort to carry out an Intensified skunk- suppress ion 
rabies-eradication program in eastern Montana. The objectives were to halt the 
western migration of skunk rabies and to eliminate all foci of infection in the 
skunk population. 

The cooperation of Montana County Commissioners, U. S. Bureau of Sport Fisheries 
and Wildlife, Montana Fish & Game Commission. Montana State Board of Health, Mon- 
tana Livestock Commission, Montana Cooperative Extension Service and the office 
of the Governor was solicited and willingly obtained. A committee, consisting of 
representatives of the Montana Livestock Sanitary Board, Montana Fish & Game Com- 
mission, U. S„ Bureau of Sport Fisheries and Wildlife, Montana Livestock Commis- 
sion, Montana State Board of Health and Montana Cooperative Extension Service, 
investigated proposed procedures for a skunk-suppression rabies-eradication pro- 
gram. The cooperative inter-agency recommended program was activated. 



m 



The willing cooperation of each of the above agencies for the common good of the 
people of Montana, lending their special talents and assistance, portends well 
that the program will be successful. 

Scabies 

In December, 1965, it was reported that Montana cattle were in a feedlot at Somis, 
California, containing about 10,^00 head of cattle found to be infected with 
_Psoroptic scabies. The feedlot contained 58I head of Montana cattle, consigned 
in 9 shipments. It was impossible to determine the origin of the outbreak and 
Montana cattle were suspect. 

It was determined that the Montana cattle originated from 151 ranches located in 
27 counties. It was imperative to maintain the health status of Montana's cattle 
industry and inspect the herds of origin of all the cattle in the feedlot. A 
total of 32,192 cattle was inspected and, where necessary, skin scrapings were 
submitted for laboratory examination. All cattle and laboratory examinations 
were negative, thus, again, avoiding a costly eradicacion program and an embargo 
against Montana cattle. 



Administration Division Report PAGE 6 



Tuberculos is 

Tuberculosis in chickens, caused by M ycobacterium avium , results in unprofitable 
poultry production. Even though good poultry husbandry and management practices 
can eliminate tuberculosis from poultry flocks, altogether too many flocks have 
tuberculosis in Montana, 

Swine tuberculosis almost always finds Its origin from Infected chickens. This 
results in large numbers of parts of swine, and even total carcasses, being con- 
demned on meat Inspection. 

Avian tuberculosis also results in sensitizing cattle to the tuberculin test and 
producing small mesenteric lesions In cattle. This greatly interferes with and 
complicates bovine tuberculosis eradication efforts. 

U Is recommended that the Montana Livestock Sanitary Board give serious consld^ 
eratlon to the adoption and enforcement of regulations that will effect the eli- 
mination of tuberculosis from Montana poultry flocks. 

Vibriosis 

Vibriosis In cattle In recent years posed a serious threat to economical produc- 
tion of beef cattle. The Trivalent Vibrio fetus bacterin developed by the Montana 
Veterinary Research Laboratory and extensively field-tested by the Ray Foundation 
of Montana was produced commercially and became available to the industry during 
the first part of 1966. 

The bacterin, from field-test results, promises to provide a means to control and 
prevent vibriosis. 

Distribution of Causes of Animal Diseases 

We wish to call particular attention to the distribution of animal diseases re- 
ported during the fiscal year and to their causes, as shown In the Disease Con- 
trol Division Report. (Page 48) 

Virus-caused diseases were responsible for over 50% of diseases reported in cat- 
tle. It clearly Indicates that these are serious disease threats and will have 
to be handled in the future. Such diseases as shipping fever, rhinotrachei tis, 
enzootic bovine abortion, mucosal-vi rus diarrhea, vulvovaginitis, rabies, encepha- 
litis, bluetongue, transmi ssable gastroenteritis and others predominate the dis- 
ease picture in livestock today. More research, Increased diagnostic capability, 
effective immunizing agents and Increased knowledge of the behavior of the dis- 
eases will have to be obtained to effectively deal with many of them. We recom- 
mend more emphasis be placed on the cause and control of the increasing viral 
diseases. 

Diseases caused by interna] and external parasites, this past fiscal year, were 
responsible for 81% of the sheep disease problems reported. External parasites, 
such as lice and sheep keds, and Internal parasites, such as round worms and 
tapeworms, are primarily responsible. These parasites can be effectively con- 
trolled through application of proper management and modern treatment. 



Administration Division Report PAGE 7 



The diseases for which the causes remain unknown were particularly significant in 
cattle, accounting for over 17% of the diseases reported. They have been and re- 
main costly to the industry. The diseases of "cancer eye", "pink eye", "asthma" 
and "water belly" take too great a toll. The hope for reduction of these dis- 
eases rests in finding the cause through research, early detection and proper 
treatment. 



MILK & DAIRY INSPECTION DIVISION 

Another year can be added to the many without a report of a milk-borne disease 
outbreak from the consumption of fluid milk. This demonstrates the effectiveness 
of the milk and dairy inspection work being carried out. This also demonstrates 
the wisdom of enforcing requirements that dairy herds be free of such diseases as 
brucellosis and tuberculosis. 

The Montana Livestock Sanitary Board Official Regulations pertaining to "Dairies, 
Milk Plants, Milk and Milk Products" were revised in September, 1 965, in consul- 
tation with dairy industry representatives, to conform with the requirements of 
the U. S. Public Health Service 1 965 recommended Grade "A" Pasteurized Milk Or- 
dinance . 

Plans have been formulated and equipment provided to start routine testing of 
milk samples for the detection of pesticides in the fall of 1 966. 

Meetings with industry representatives have launched procedures for the industry 
to conduct Wisconsin Mastitis Tests on producer-dairy milk samples to implement 
the milk plant's quality-control-program and to stimulate mastitis control at the 
dairy farm. 



MEAT INSPECTION DIVISION 

The availability of additional funds on July I, 1965, provided by the 39th Legis- 
lative Assembly, made it possible to establish meat processing and labeling in- 
spection In all establishments operating under the Montana Meat Inspection Act. 
Meat processing and labeling inspection has long been a requirement under Montana 
Laws and Regulations. The funds provided enabled the Livestock Sanitary Board to 
meet their responsibilities assigned to them by these Laws and Regulations. 

Meat processing and labeling inspection was Inaugurated In ^establishments dur- 
ing the fiscal year. The cooperation of the meat plants and Industry has been ex- 
cellent in establishing this, phase of the meat Inspection. All plants required 
to have meat Inspection have done so, with the exception of k small meat proces- 
sing establishments in Missoula. Every effort Is being made to obtain their com- 
pliance before resorting to required legal action. The establishment of proces- 
sing and labeling inspection required the obtaining and training of all new per- 
sonnel. Excellent progress has been made. 

It appears that meat Inspection demands will continue to increase. Eight addi- 
tional establishments were granted official meat inspection this fiscal year. It 



Administration Division Report PAGE 8 



is anticipated that at least k more will request meat inspection during the next 
fiscal year. 

The report of the Meat Inspection Division, showing that 1,571,005 pounds of meat 
and meat products were found totally unfit for human consumption and condemned, 
speaks more eloquently than words to justify this public health service. 



ARTI FICIAL INSEM I NATION 

In accordance with Chapter 37, Laws of 1953, 230 licenses were issued to in- 
dividuals during the fiscal year to practice artificial insemination in Montana. 

On behalf of the Montana Livestock Sanitary Board, the Animal and Range Sciences 
Department of Montana State University held two courses on artificial insemination 
and sanitation during the fiscal year to assist individuals in qualifying for a 
license. Duly appointed representatives of the Livestock Sanitary Board, who 
serve on the staff of Montana State University, conducted licensing examinations 
twice during the fiscal year to determine qualifications of license applicants. 



GR ANT TO THE VET ERINA RY RESEAR CH LABORATORY 

The Montana Livestock Sanitary Board approved a grant of $10,000 for the fiscal 
year to the Montana Veterinary Research Laboratory, specifying that the entire 
amount was to be used to assist in establishing and carrying out a research pro- 
ject on "calf scours". The following progress report was submitted by the Veter- 
inary Research Laboratory:

A Colostrum, amounts absorbed, antibody content. 

B Toxigenicity and serological characteristics of iso- 
lated bacteria. 

C Attempt to correlate resistance of calves with "A" 
and "B" above. 



Administration DIv i sion Report PAGE 9 



Results : 

1 Many bacteria have been Isolated from fecal samples of calves. 
Over 600 £. coU and C. p erf rinqens isolates have been obtained 
and are being processed for serological characteristics. It 
has been observed that "normal" newborn calves contain only E. 
col i t while all but one of the scouring calves contained large 
numbers of both IE. col i and C. perfringens , Types A and C. 
Anerobes were not isolated from a scouring calf that had re- 
ceived two treatments. 

II Studies on the effect of bacterial cultures or toxins are in- 
conclusive because we have not had enough animals on the ex- 
periment. This work will be carried to completion, and the 
data obtained will be used to design future experiments with 
larger groups of calves. 

Ill It is much too early to arrive at any conclusions from our 
laboratory investigations in which we are attempting to obtain 
some form of correlation between the quality and quantity of 
ingested colostrum and resistance to challenge. 

Attendance was made to the Western Regional Committee Meeting on Enteric 
Diseases of Newborn Calves. The Veterinary Research Laboratory is a 
member of this committee and participates in the annual meeting. Ten 
different Western Experiment Stations are investigating this problem on 
a regional basis. The meeting serves for the correlation and exchange 
of information on this subject of calf scours and to eliminate dupli- 
cation of effort. 

In summary, we feel that, although substantial progress has been achieved 
during the beginning studies and preliminary results are encouraging, 
much work remains to be accomplished before the causes of the disease 
syndrome are fully understood and the time when reliable methods of pre- 
vention^ treatment and control are established."

DISEASE CONTROL DIVISION REPORT PAGE 36 



CATTLE DISEASES 

Montana veterinarians reported kk cattle diseases involving 31,182 cattle on 5,893 
ranches. This is an increase of k diseases, k,kBk cattle and 115 ranches from the 
previous fiscal year. 

Anaplasmos is 

A total of 90 cases of anaplasmos is on 69 ranches was reported by Montana veterin- 
arians. This is a reduction of 179 cases and 61 ranches from the previous fiscal 
year. 

The Diagnostic Laboratory tested 715 blood samples from cattle for anaplasmosis, 
with the Complement-Fixation Test, and 46% showed positive or suspicious reactions. 
The Capillary Agglutination Tube Test for anaplasmosis was applied to 637 bovine 
blood samples, with 32% giving a positive reaction. The tests, again this fiscal 
year, confirm that the number of carrier animals in the Montana enzootic area is 
high. The potential remains for a recurrence of the heavy losses reported during 
the summer and fall of 1964. 

The capability of the anaplasmosis Infectious agent being carried over from year 
to year in ticks, deer and possibly other wildlife leaves only one practical way 

to attempt to control anaplasmosis In a range or semi-range area in Montana 

that way is through an effective Immunizing agent. 

Fort Dodge Laboratories, Fort Dodge, Iowa, started, during the year, to commer- 
cially manufacture the anaplasmosis vaccine "Anaplaz", developed by the College 
of Veterinary Medicine, University of Oklahoma. Reports received indicate that 
about 7,517 doses of the vaccine were used In Montana during the fiscal year. 

In order to evaluate the effectiveness of the vaccine in Montana, Fort Dodge Lab- 
oratories gave 600 doses to the Livestock Sanitary Board to be used In field- 
trials. The vaccine was administered to 248 cattle In three different herds in 
the enzootic area. An equal number of cattle was left unvaccinated In each herd. 
Deputy State Veterinarians will investigate all illnesses and death losses during 
the summer and fall and will obtain blood samples after the anaplasmosis season 
late In the fall of I966. 

Bruce 1 losls 

A total of 160,969 cattle was tested for brucellosis, revealing 602 reactors 
(0.31%) and 6,37*+ suspects (3.35%). Of the total tested, 51,886 were tested out- 
of-state and 62,909 were tested from samples collected in Montana on the market- 
cattle- testing program. The total number of cattle tested was 37,091 more than 
was tested during the I965 fiscal year. The percentage of reactors was 0.35% in 
the I965 fiscal year, compared with 0.31% in the 1966 fiscal year. 

There were 10,969 Brucellosis Ring Tests made on milk and cream samples - a de- 
crease of 2,442 from the previous year. Thirty-seven (0.34%) were suspicious to 
the test, compared with 0.32% in the I965 fiscal year. 

There was a reduction of brucellosis infected herds in Montana. With 37 herds 
from last year, 44 additional infected herds were found during the past fiscal 



Disease Control Division Report 



PAGE 37 



year. A total of 51 herds were able to eliminate brucellosis, leaving 30 herds 
still under brucellosis quarantine at the end of the fiscal year. 

Nineteen counties were recertified as Modif ied-Certif ied Brucellosis Areas during 
the fiscal year.

Fluoros is 

Montana veterinarians reported fluorosis in 21*+ cattle on six premises during the 
fiscal year. Again, as last year, all cases were reported in an area adjacent to 
a phosphate plant. 

P.hinotrachei tis 

Montana veterinarians reported 2,814 cases of rhi notracheitis on sixty-six ran- 
ches. They also reported 295 cases of vulvovaginitis on two ranches. The labora- 
tory was unable to attribute a bacteriological cause to 520 aborted feti. From 
recent studies, it can be assumed that the cause of the vulvovaginitis and a share 
of the bacteriological ly negative aborted feti were due to the infectious bovine 
rhi notracheitis virus,. 

Shipping Fever 

This disease was - by far - the most serious disease problem experienced by cat- 
tlemen this past fiscal year. Veterinarians reported 11,152 cases on four hundred 
thirty-five ranches. 

Tuberculosis 

The tuberculin test was applied to 2,836 dairy cattle and 11,547 beef cattle - a 
total of 14,383. Two cattle in 2 dairy herds and two cattle in 2 beef herds gave 
positive reaction and were under quarantine at the end of the fiscal year. 

A total of 114,795 cattle was slaughtered under backtag or brand identification. 
Seventy-four cattle (0.064%) were found to have lesions grossly resembling tuber- 
culosis lesions. 

A review of information received on investigation of gross lesions obtained at 
slaughter for the past four years reveals the following: 

1. 156 cattle were reported with gross lesions. 

2. Location of Lesions ; 

72% Mesenteric lymph nodes. 

10% Mediastinal lymph nodes. 

9% , Cervical lymph nodes. 

9% Bronchial lymph nodes, pleural and lungs. 

3. Histological Examination : 

35% , „ Suggestive of tuberculosis. 

11% Migrating parasites. 

27% Acid-fast bacilli demonstrated. 

27% , Acid-fast bacilli not demonstrated. 

4. Mycobacterium isolations : 

24. 7% Mycobacterium avium . 

3.2% Runyon Group IV. 

1.1% Mycobacterium bovis . 

71.0% No isolation made. 



Disease Control Division Repor t PAGE kO 



A total of 58 herds, containing 5>^32 cattle, was tested (from which cattle were 
found to have gross lesions at slaughter) in which histological examinations were 
suggestive of tuberculosis, or acid-fasts were demonstrated, or a Mycobacterium 
was isolated. Three reactors were found in one herd. Slight gross lesions were 
found In two of the reactors.., Myc obacter ium avium was isolated from one. We 
have yet to find bovine tuberculosis in a herd of origin of cattle from which 
slight mesenteric lymph node lesions or other lymph node lssions were found at 
slaughter. In some instances, chickens with tuberculosis were found to be asso- 
ciated with the cattle. 

Twelve counties were reaccredited Modi fied-Accredi ted Tuberculosis Areas during 
the fiscal year. 

Vibriosis 

Montana veterinarians reported 129 cases of vibriosis on twenty-four ranches. The 
laboratory Isolated Vlbrp-fe tus from 57 cattle specimens. 

Viru s Abortion 

The enzootic bovine abortion virus has been definitely isolated from a herd of 
105 cattle in which a 70% abortion rate had occurred. It is suspected this virus 
is more widespread than heretofore suspected. 



HORSE DISEASES 

A total of 11 diseases in 1,231 horses was reported on seven hundred sixty-two 
ranches. This Is an Increase of k diseases, 255 horses and 303 premises over 
last year. 

Encephal it Is 

Montana veterinarians reported 333 cases of equine encephalitis on two hundred 
eighty-five premises. This was a marked increase of 32k cases and 276 premises 
over the previous fiscal year. 

The Rocky Mountain Laboratory summarized their studies of the encephalitis out- 
break In the summer and fall of 1965 as follows: 

" Human Specimens 

Sera from 5^cases submitted and I7 (31.5%) were serologically confirmed 
for Western Equine Encephalitis. Thirty-six were negative; but from 7 
of these, only a single (acute) specimen was received. One was con- 
firmed for St. Louis Encephalitis. 

Horses 

Sera from 55 horses submitted and 20 (36.3%) were serologically con- 
firmed for VJestern Equine Encephalitis. 



Diseas e Co ntrol Division Report PAGE k) 



The Western Equine Encephalitis virus was active in August, 1965, These 
were confirmed clinical cases In man and horses. High infection rates 
were found in Culex tarsa l is mosquitos and in chickens. Evidence of in- 
fection in snakes lias not been found. This question will be investiga- 
ted further when snakes come out in the spring. After a season when 
there was so much activity of the virus, they should be positive if 
they play a role in the ecology of Western Equine Encephalitis." 



SHEEP DISEASES 

Eighteen sheep diseases were reported during the fiscal year by Montana veterin- 
arians on one hundred eighty-eight ranches in 12,883 sheep. This was the same 
number of diseases reported last year, but an Increase of eighty-seven ranches 
and 5,091 affected sheep. 

Epididymitis 

Montana veterinarians reported 79 cases of ram epididymitis on fifteen ranches. 
The laboratory tested 362 blood sera, using the REO Complement-f ixation Test and 
3*+% gave reactions to the test. 

Foot rot 

Infectious foot rot continued to remain a problem In four bands in Montana. Per- 
sistent efforts are continuing In order to achieve complete eradication. 

P ediculosis 

Due to complaints from buyers of lambs having lice, particularly from one part of 
the state, many flocks of sheep in that area were inspected. All bands Inspected 
in which lice were found ( Damalinla ovis) were placed under quarantine, In accord- 
ance with Regulation 110^. A total of kB bands, containing about 10,800 sheep, 
v-. -i~ quarantined. At the end of the fiscal year, 23 bands, containing 6,3 i0 sheep 4 
hod been dipped and released from quarantine.

S WINE DISEASES 

Montana veterinarians reported 12 swine diseases In 570 swine on seventy-four 

premises. 

Bruc e 1 losis 

No clinical evidence of brucellosis was reported, The laboratory did not isolate 
a Bruce 1 la organism from any swine, Serological tests made on 293 swine blood 
samples did not disclose any reactors. 

The following herds became validated or were revalidated Brucellosis-free Swine
