不同饲养模式对新疆褐牛(肉用类型)生长性能与繁殖性能影响的研究进展OA

Xinjiang brown cattle(meat type)have strong adaptability,high intramuscular fat content and fast growth rate.Currently,their rearing mainly adopts three modes:grazing,stall feeding and semi-grazing semi-stall feeding.The grazing mode relies on natural pastures and has undergone technical optimization,but still faces ecological pressure,seasonal restrictions and insufficient management.The stall feeding mode has high fattening efficiency and outstanding growth and reproductive performance of beef cattle,but is constrained by feed costs,environmental control and meat quality and flavor.The semi-grazing semi-stall feeding mode combines the advantages of the former two,but has challenges such as complex management and stress during seasonal transitions.To address the current predicament,this paper reviews the overview and existing problems of the three rearing modes and their impact on the growth and reproductive perfor-mance of Xinjiang brown cattle(meat type),and looks forward to future research directions,which can provide practical ideas for improving the quality and efficiency of beef cattle breeding.
