Show Dairy Herd Improvement Association Shows Result The well-rounded- program of the Dairy Improvement Associations, Associa-tions, begun in a small way 40 years ago, is each year now showing show-ing wider results. Effects of the use of proved sires are especially significant, resulting as they do in a healthy rise of the average milk production of all daughters of proved bulls instead of outstanding outstand-ing milk production records of just a few individuals. Last year the average production for all of the Nation's 26 million dairy cows was less than 4.600 pounds of milk, for the half million cows of the improvement im-provement association herds it was 8,300 pounds. With the increased interest in record keeping and the rapid development of artificial insemination, in-semination, we can look forward to continuing increases in dairy cow efficieny. At Bellsville, for example the USUA has some proved Hol-stein Hol-stein bulls all of whose daughters average over 20,000 pounds of milk and over 800 pounds of butterfat a year. |
