Dairy progeny testing in Finland
1973
Ulf Lindström | Kalle Maijala | Mikko Varo
An account is given of the present method of progeny testing of dairy bulls. Correction factors used are presented and an example of their application given. It is noted that progeny tests for milk yield based on less than 30 daughters have a low repeatability. There were no significant changes in the ranking order of AI bulls in different geographical areas. In the Ostrobothnia area, however, the progeny tests seemed to be slightly less accurate than in other regions.
