Popis:	The data consisted of 369 lactation records for calvings over a sixteen-year period (1972-1987) and included only cows that had normal milk records. The data were analysed using a linear model containing the fixed effects of parity, year of calving and season of calving. The least squares means ± S.E. were 1,273±58.4 kg for milk yield, and for postpartum body weight (kg) at 2, 3 and 4 months after calving were 343.40±3.96, 346.10±4.10 and 352.54±4.26 kg, respectively. With the exception of season of calving, the effects of parity and year of calving were significant (P
