Show SPRING PASTURE IS NOT HARMFUL North Carolina Finds Milk Is Richer in Butterfat. Tt's mostly tradition, and not facts, that loads' many dairymen to believe that tli,; quality of milk dc-preciates when the cows are turned from the dry feed of the stable to the succulent green feed of the pasture. "Yet we have a few dairymen and many consumers who believe this," says J)"ed M. Halg of the animal husbandry hus-bandry department at the North Car- . olina state college. "We have just completed a test with nine cows in the herd here at the college whi-2h shows that Instead of the animals giving giv-ing a lower quality of milk in the spring, it is materially richer in butterfat." but-terfat." Last winter, Professor Haig selected select-ed nine cows and fed them cottonseed cotton-seed bulls as the sole roughage for a period of ten weeks. No succulent feed was given during the period. The average daily milk production was 201.0 pounds testing 4 G4 per cent fat. The cows were then changed from the hulls to corn silage and hay and, after giving time to accustom themselves them-selves to the change, the same data was again collected. With this feed, each cow of the nine produced 209.1 pounds of milk per day testing 4.88 per cent fat. On May 4, the nine cows were turned on a rich pasture consisting of green wheat and crimson clover. Again they were allowed time to adjust ad-just themselves and the data again collected. The average dally production produc-tion in this case was 212.9 pounds of milk each day testing 5.37 per cent fat. Throughout each of these three tests, the grain ration remained con-. con-. stant and supplied a balanced ration. However, this shows that silage is better bet-ter than the dry feed and a good pasture pas-ture is better than silage. Professor Haig states that succulent feed is important im-portant in the da ivy business not only for the maintenance of healthy cows but also for the amount and quality of milk produced. |
