The Dairy Herd Improvement Association Program Classic Reprint

Excerpt from The Dairy-Herd-Improvement Association Program The supervisor visits each farm one day each month. Usually he arrives in the, afternoon. That evening he weighs the feed Of each cow, weighs the milk, and takes a sample Of the milk for testing. He records all figures in the barn book, from which he transfers them to the herd-record book. The barn book is the supervisor's record of the work, and the herd-record book remains in the possession Of the farmer as his record Of the work. The next morning the supervisor again weighs the feed, weighs the milk, and takes a sample Of the milk for testing. He mixes the two samples Of each cow's milk thor oughly and then tests the composite sample for percentage Of butter fat. The day the test is made is considered as the middle day of the testing period, and the record Of that day is multiplied by the number of days in the testing period. From the herd-record book the farmer can at any time get the record Of his herd and Of each cow for every month from the beginning of the testing year. He can also get totals for each cow. The herd records include feed cost and production Of milk and butterfat. The individual-cow records include all this and the number Of pounds Of each kind Of feed consumed. At the end of the testing year the farmer can get from the herd record book the yearly summary Of his herd and Of each cow. AS the years pass he can compare the yearly records and determine what progress his herd is making and what progress each cow is making. If the herd-record books are filled out completely and carefully, the farmer can get all this information quickly, and from this knowledge of the records Of his cows he can go forward, without guesswork, in the improvement of his herd. With a well-kept herd-record book, the farmer is able to build up his herd. Rapidly through careful selection, planned breeding, and proper feeding.

Excerpt from Dairy Herd Improvement Letter, Vol. 53 This year's increase in the production averages of 800 pounds of milk and 28 pounds of fat for cows on official test is unusual compared with the average increase over the previous 11 years of 150 pounds of milk and 5 pounds of fat. It is explained by the fact that (1) nine States had average milk production increases of 820 to pounds on cows, (2) seven States had average milk production increases of 700 to 775 pounds on cows, and (3) that almost all other States had increases in average milk production ranging up to 680 pounds. Fourteen States had increases in fat production of 28 to 58 pounds on cows, and 14 States had increases of 20 to 27 pounds on cows.

Excerpt from Dairy Herd Improvement Letter, Vol. 57: April 1981 Averages in tables 1 and 2_ are for all, active ai, inactive ai, and non-ai bulls. Previously there were -no separate averages for inactive AI bulls, but the averages except for pd% could have been computed from the other averages distributed with the active AI list. Active AI bulls were those designated as active by the controlling organization. Inactive AI bulls had a stud code and had entered the stud at least 3 months prior to the Summary date but were not in active service at the time of the Summary. All other bulls were given non-ai status. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

"Nearly 50 years ago a few progressive dairy farmers in Michigan organized the first cow-testing association in the United States. They wanted to improve the profitableness of their herds. They hired a tester to weigh and test the milk of each cow and keep a record of her food cost and income. They wanted that information so the could cull the low producers from their herds and feed the rest more economically. In the first 4 years of their pioneer effort these Michigan dairy farmers doubled the average profit per sow. since then thousands of other dairy farmers have followed their example with equally striking results. The cow-testing movement grew and eventually expanded into the present-day dairy-herd-improvement-association program. Members of these associations now use their records not only to test the cows but to prove the bulls. The improvement they have brought about in their herds is one of the outstanding 'success' stories in agriculture. No herd is so good that it cannot be made better by effective culling, good feeding, and the use of production-tested breeding stock. Breeding records and records of production, feed cost, and income are essential for carrying on such an improvement program. Membership in a dairy-herd improvement association is one of the best and most economical ways for any dairy farmer to obtain the necessary records."--Page ii.
