This book was released on 1966 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production records used were all converted to a comparable based, 305 day lactation period, two times a day milking, and mature equivalent (305 days-2-x-ME) of 71 cows from four Holstein bulls and 59 cows from four Jersey bulls were used for the study. The Equal Parent Index, Regression Index and Herd-Mate Average were calculated for each of eight bulls using five daughters and using all daughters. The study consisted of data collected from 1957 to 1965 in Oregon State University dairy herd. The use of records from five randomly selected daughters gave as good an estimate as was obtained when the records of all daughters were used for indexing dairy bulls. In comparison between the Regression Index and Herd-Mate Average, neither method gave a clear-cut estimate; the Regression Index tended to give an overestimate while the Herd-Mate Average tended to give an underestimate of a bull's transmitting ability. All indexes except the Herd-Mate Average for Holstein bulls failed to give an accurate estimate of the average actual production of the daughters. There was a significant difference between the Holsteins and Jerseys for both milk and butterfat production. Also, the three methods differed significantly from one another in the estimates of transmitting ability of sires.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Studies in Milk Secretion, Vol. 17: Relation Between Milk Yields and Butter-Fat Percentages of the 7-Day and 365-Day Tests of Holstein-Friesian Advanced Registry Cattle During the course Of their development two of our leading dairy breeds, the Jersey and. The holstein-friesian, have made extensive use Of the 7-day test. The Jersey breed has now prac tically discontinued the use Of the 7-day record advocating the 365-day record as the only measure Of the cow's worth as a milk producer. The discussion of the merits of the Short time test and the long time test has recently entered a highly controversial stage even among its chief adherents, the holstein-friesian breeders. Few, if any, Of the supporters Of either camp have actively asserted that the long time test was not desirable. The contest has centered on the validity. Of the 7-day test as a meas ure Of the cow's subsequent performance. This question is intricate. It is really one phase of the larger question of the normal fluctuating variability of milk yield. In fact, it is from this angle that the authors were led into this problem, for whatever Significance may be attached to this variability, a fairly comprehensive knowledge of its magni tude forms a necessary prelude to the further use Of such data for genetic studies.
