Book excerpt: Excerpt from List of Sires Proved in Dairy Herd Improvement Associations, 1938 In dairy herd-improvement association work a sire is termed a proved sire when the production records of at least five of his unselected daughters have been compared with the production records of their dams. Such comparisons may show that a s1re has transmitted high medium or low-producing ability to his daughters. To say that a sire is a proved s1re, therefore, does not necessarily mean that the sire is a valuable sire; it merely means that the production records of five or more of his unselected daughters and their dams have been compared on a uniform basis.

Book excerpt: Excerpt from List of Sires Proved in Dairy Herd Improvement Associations, 1942 Therefore, all information on each proved sire is sent to the owner Of the sire as rapidly as the data accumulate and are tabulated. Often, however, the information will also be Of interest and value to other dairymen, especially those whose herds carry related blood lines. Bringing together all proved-sire information annually, as is done in these lists, is expected not only to be currently useful to all dairymen in selecting promising herd Sires but also to assist materially in spreading and perpetuating the influence Of the outstanding sires. Although these lists emphasize the use Of proved sires to improve dairy herds, the importance Of using dams Of proved transmitting ability is not minimized.' The sire and dam contribute equally to the inheritance Of the progeny. In a broad dairy cattle improvement program, however, the sire is the most potent factor for improving the producing capacity Of our dairy cattle. The influence Of the Sire can be widely dispersed since the Sire may have great numbers Of progeny each year; whereas, the dam will have only a few progeny during her entire lifetime. Aside from the proved sire, the best prospect for improving production in dairy cattle is through the use Of the sons Of proved parents.

This book was released on 2018-09-14 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from List of Sires Proved in Dairy Herd Improvement Associations, 1935-37: Arranged by Breeds The proved-sire record as summarized here should be considered merely as an indication and not as conclusive evidence of the breeding value Of the sire in question. If the difference between the average butterfat production of the dams and that Of the daughters is less than 25 pounds, additional dam-and-daughter comparisons may con ceivably reverse the results Of the summary. In general, however, a proved-sire record that includes a large number of dam-and-daughter comparisons can be considered as better evidence Of the sire's breeding value than a record that includes only the minimum number Of comparisons permitted in sire-proving work. Also, the greater the number Of lactation records included in the average record Of each dam and daughter the more dependable the proved-sire record. To make the most intelligent selection of a sire, the dairyman Should use these proved - sire records to single out the most promising sire and then make every effort to supplement these data with additional information gathered from the herds in which the dams and daughters made their records. Particular attention should be given to the feeding practices and environmental conditions under which the records were made, in order to be assured that the records Of the daughters were not made under more favorable conditions than those Of the dams or vice versa. It is especially important to deter mine that there has been no selection Of daughters in making the comparison.

Book excerpt: Excerpt from List of Sires Proved in Dairy-Herd Improvement Associations, 1948 If the difference between the average butterfat production Of the dams and that Of the daughters is less than 25 pounds, the increase or decrease should not be considered as significant. If the daughters Of a sire have an average butterfat production Of 25 or more pounds above that Of their dams the sire may be considered as raising the production Of the herd in which he is used. If the daughters' average butterfat production is 25 pounds or more below that Of their dams the sire may be considered as lowering the production of the herd in which he is used, in which case he should be discarded from that particular herd. Such a sire may prove useful in a herd Of Iower-producing dams, however. TO make the most intelligent selection Of a sire, the dairyman should use these proved - sire records to single out the most promising Sire and then make every effort to supplement these data with additional in formation gathered from the herds in which the dams and daughters made their records.
