140 (b) Gross receipts per annum : Rs. As, Ps. 1. Price of ghee, produced out of milk; 5* maunds at 4* seers of ghee for every maund of milk; valued at Re. 1-0-0 per seer...........216 0 0 2. Price of dung, 8 cartloads at 8 annas per cartload........... 400 3. Value of the young one born..... 10 0 0 Total . 230 0 0 Thus the net profit in the case of a milking she-buffalo is Rs. 90 per annum. It is necessary to explain why in calculating the receipts we have converted milk into ghee and taken its price as though the income from milk was the same as from ghee. The reason is this. The majority of farmers of this village sell ghee for which there is a market in Bulsar. It is not possible to send milk to Bulsar, which is at a distance of nine miles, because the facilities of conveyance are inadequate. We may note that when dry, a she-buffalo is usually taken out to graze during the day. She is given grass and straw at night. In the rainy season she is allowed to graze green grass. No concentrated food is given to her. The cost of maintaining her when dry may be taken at Rs. 12 per annum. The only income received from her during this period is manure which may be reckoned at Rs. 2. This leaves a net loss of Rs. 10 when the she-buffalo is dry. Yet she is kept by the farmer because this loss is much more than compensated for, in the future, when she gives birth to a calf, by the value of the calf and the milk.
