The use of inbreeding for obtaining dairy bulls

, : The use of inbreeding for obtaining dairy bulls. Osobennosti plemennoi raboty s sel' skokhozyaistvennymi zhivotnymi: 51-54

For outbred and inbred progeny-tested bulls at a farm in the Moscow region of the former USSR in 1980-87, data are tabulated on body weight, body measurements, semen characters, CR achieved and milk yield. There were 15-24 and 232-335 bulls per trait in the 2 groups respectively.

Inbreeding intensities were studied in 17,796 young bulls of Black-Pied dairy breed (born between 1974 and 1985) from various bull raising stations. The results revealed that about 9% of the bulls were almost only moderately inbred, although the p...

Data on 17 795 young bulls born between 1974 and 1985 were analysed. 1564 (8.9%) were inbred: 278 (1.6%) had an inbreeding coefficient of 12.5%, 564 (3.2%) were 6.25% and 722 (4.1%) were 3.125% inbred. The overall av. coefficient was 0.53%, and in...
