Show 1 - COW UNDER TEST CONDITION Animal Produces Sixty Per Cent Mor Milk and Butterfat Than When With Herd. Why cows under test conditions produce pro-duce on lie average GO per cent more milk and butterfat than those kept under un-der ordinary herd conditions is a problem prob-lem the dairy division, United States Department of Agriculture, is still unable un-able to solve. In the recent annual report re-port of the bureau of animal Industry, It is stated that only 20 per cent of the Increase has been satisfactorily accounted ac-counted for. Five per cent was due to keeping cows in box stalls compared with stanchions. Other experiments conducted on the government farm at Beltsville, Md., show that with cows of average production pro-duction Irregular milking was not detrimental to milk nd butterfat production pro-duction and that the cost of production Is Increased when cows are exercised to the extent of being driven three miles a day. However, exercise was found to Increase slightly the fat content. con-tent. A considerable number of calves were fed with a nipple as compared with drinking from a pall. Results showed no advantage In using nipples. Pectin pulp, a by-product in the manufacture of pectin from apple pomace, was found to be less palatable, and less valuable as a dairy feed than beet pulp. The use of molasses in the dairy ration ra-tion is not justifiable, the government report shows, for a group of cows that were given molasses in addition to the regular ration produced slightly less than the group that received the regular regu-lar ration only. A 20-year experiment, now in progress prog-ress at Manhattan, Kan., will determine deter-mine to what extent milk production can be developed without sacrificing desirable beef type. The work was started in 1915 and Shorthorn cattle are being used. |
