Michigan and Northeast dairy herds that produced young bulls for AI sampling from 1974 to 1981 and 1978 to 1981, respectively, and those involved in progeny testing were compared with their contemporary DHI herds. The 1985 lactation records of Michig

Characteristics of 6,013 first lactations by daughters of 12 Holstein artificial insemination sires were studied with analyses of variance to investigate interactions of sires with approach to age correction and manner of extending voluntary terminat

Sires were evaluated by daughter average and mean weighted difference of first lactation daughters. Herdmates were restricted to first lactation daughters of the other sires in a specific comparison. With large numbers of daughters per sire, the daug

Summary Records of milk and fat produced by each cow during a single day of test were obtained from 87 Holstein herds that had never been enrolled on any production-testing program. Each record was adjusted to its 305-day mature-equivalent, and the a

Simulated records of 1,556 2-yr-old dairy cows with dam information were used to test the accuracy of a modified method of Smith (4) for estimation of genetic and environmental trends in production. Of the total number of cows, 1,008 were daughters o
