Variability of milk production within the contemporary groups in prediction of breeding value

Popis výsledku v původním jazyce

Calving frequency within the year and variability of milk production within the herd-year-season (HYS) for cows in the 1st to 3rd lactation of the Czech Pied (C) and Holstein (H) cattle calved in 1996 to 1997 was determined. The herds were divided into seasons on the basis of the number of observations from 2 to 15. Systematic effects of the environment (HYS) and third degree polynominal regression for the age to at 1st calving, for the service period, and previous calving interval were taken into accouinto account. With the increasing number of individuals within HYS, the season was prolonged and resulted in the increase of residual variability. In dependence on the number of individuals within HYS and lactation number, in C cattle the systematic effeinto account. With the increasing number of individuals within HYS, the season was prolonged and resulted in the increase of residual variability.
