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.
