Investigation of major fattening traits of male crosses F1 generation of German Fleckvieh breed and domestic Simmental breed

Abstract

Major fattening and growth traits of performance tested bulls from two groups are presented in this paper. Bulls obtained in pure breed Fleckvieh x Fleckvieh were investigated/evaluated in test stations in Germany, and male crosses with Domestic Simmental cows in domestic centers for AI (Krnjača and Velika Plana). In observing two groups of young bulls statistically significant differences were registered (p (lt) 0,01**) for following traits chest depth, chest girth, and daily gain, whereas for body mass at the end of test and height of withers differences were at level p> 0,05 ns. Group of young bulls F x F tested in Germany achieved in average greater chest depth and chest girth and realized higher daily gains during test period. Group of crosses tested in our conditions in domestic test stations realized higher values for length of carcass and almost identical body mass at the end of test period. In other words, improvement of production traits and correction of exterior characteristics of domestic population of cattle through import of breeding animals and their semen is justified only when positively tested breeding material is imported which is adequate for our purpose and breeding objective.

U radu su ispitane važnije osobine tovnosti i porasta kod dve grupe bikova testiranih performans testom. Bikovi dobijeni u čistoj rasi Fleckvieh x Fleckvieh ispitani su u testnim stanicama u Nemačkoj, a muški melezi sa kravama domaćeg simentalca ispitani su kod nas u centrima za VO (Krnjača i Velika Plana). Posmatrajući dve grupe mladih bikova, ustanovljene su statistički značajne razlike (p (lt) 0,01**) za osobine dubina grudi. obim grudi i bruto dnevni prirast, dok su za osobine telesne mase pri završetku testa i visine grebena razlike bile na nivou (p> 0,05 ns).
