Research Report on Weaning Weight of Angus and Its Crossbred Calves
摘要
Abstract
In order to investigate the growth rate of different beef cattle breeds during the lactation pe-riod in Dehong Yunnan,this study investigated a total of 125 F1 calves of 5 hybrid combinations were pro-duced by crossing Australian imported Black Angus at 2021 with Dulong cattle,Wenshan Peak cattle,Shorthorn cattle,Yunling cattle,and Japanese Wagyu bulls,meanwhile 189 purebred Angus calves used as the control group.All calves were carefully weaned at the age of 6 months for weighing and calculating average daily gain.The results showed that the weaning weight and growth rate of the 5 hybrid combina-tions and the calves were different from each other.The weaning weights of the calves crossed with Dulong cattle,Wenshan Peak cattle,Shorthorn cattle,Yunling,and Japanese Wagyu were(127.27±18.83),(146.69±25.40),(171.98±22.34),(160.54±26.62),and(158.44±26.62)kg,respectively,and the average daily gains were(0.69±0.10),(0.79±0.14),(0.93±0.12),(0.87±0.12),and(0.86±0.14)kg,respectively.The weaning weight and average daily gain of the control calves were(162.91±25.10)and(0.88±0.14)kg.Among the hybrid combinations,only the weaning weight and average daily gain of the Shorthorn cattle crossed with Angus were higher than the control,though differences were not statistically significant(P>0.05).In contrast,calves from Angus×Dulong and Angus×Wenshan Peak crosses showed significantly lower growth performance than controls(P≤0.05).These findings provide insights into optimizing breed combinations for beef production in the region.关键词
