Comparison of Gelbvieh and Limousin sires in a terminal crossbreeding system

The Gelbvieh and Limousin breeds were evaluated for use as terminal sires over a 4-yr period (1982 to 1985). A total of 778 calves from 28 bulls (seven per year) of each breed were produced from eight two-breed-cross cow groups. Calves were raised by their dams, without creep feed, on native and ber...

Zusammenfassung:The Gelbvieh and Limousin breeds were evaluated for use as terminal sires over a 4-yr period (1982 to 1985). A total of 778 calves from 28 bulls (seven per year) of each breed were produced from eight two-breed-cross cow groups. Calves were raised by their dams, without creep feed, on native and bermudagrass pastures until weaned at an average age of 205 d. Although calving difficulty was similar, Gelbvieh-sired calves were 1.0 kg heavier (P < .05) at birth and had 2.1% higher (P < .05) preweaning mortality. They also gained 56 g/d faster (P < .01) to weaning and were 12.0 kg heavier (P < .01) at weaning than Limousin-sired calves.
