Show I EXPERIMENT IN COW FEEDING Result of Number of Tests Made by the North Carolina 8ution on Rations for Milk. The North Carolina agricultural experiment ex-periment station recently concluded a number of experiments to determine the relative efllciency of narrow and medium wide rations, for milk production, produc-tion, a report of which baa reached the department of agriculture. Eight cows from three to six weeks in lactation were fed three periods of twenty-eight days each. In the first and third periods the feed consisted five parts of cottonseed meal, four quarts wheat bran, three parts of corn-meal corn-meal and fifty pounds of corn sliago. The nutritive ratio, of this ration was about 1.4. During the second period the ration waa the same as the above except that 2.S pounds of cottonseed meal was replaced by 2.6 pounds of corn-meal, corn-meal, glvlnu this ration a nutritive ration of about 1 C7. The result of this test Indicates that the narrow ration produced 7.6 per cent, more milk fat. and Increased the fat test 0.24 per rent, and the live weight 30 pounds. The milk yield waa practically the same. |
