Abstract
The purpose of this paper is to estimate the effects of systematic factors, primarily the degree of crossing, on the standard lactation lengths of 305 days in 6 different genotypes of cows (F-1, R-1, R-2, R-3, R-4, R-5) obtained by the upgrading of the Serbian Fleckvieh (SF) to the Holstein-Friesian (HF) breed of cattle. The systematic effects included in the general linear model (GLM) exerted a significant (P (lt) 0.05) influence on the milk yield, as well as the fat yield and content. During the upgrading process, statistically significant (P (lt) 0.05) differences were recorded between the traits of the genotypes examined. With an increase in the share of HF genes, the milk yield increased from 5020 kg (F-1) to 5801 kg (R-5) and the fat yield from 176.2 kg to 201.6 kg, whereas the fat content simultaneously decreased from 3.55 % (F-1) to 3.49 % (R-5). The F-1 cows had the highest heterosis realized (h(R)) regarding the milk yield (185.8 kg), while the R-1 and R-2 cows displayed nega...tive heterosis effects (-21.0 and -205.7 kg) and negative recombination effects (r(I)). The highest value of le (regarding the milk fat yield) was recorded in the F-1 cows (6.07 kg) in comparison with the R-2 cows, which had the negative h(R) (-3.79 kg), whereas the negative r(I) was recorded in the R-1 and R-2 genotypes. The positive r(I) (regarding the milk fat content) was recorded in the R-1, R-2 and R-3 genotypes accompanied by the positive h(R).
