摘　　要：[目的]通过试验探究科尔沁肉牛犊牛最佳的饲养模式,为后续科尔沁肉牛早期补饲的推广和普及提供理论支持。[方法]选取体型相近,初生体重在34~50 kg之间健康的科尔沁肉牛犊牛60头,分为对照组、补饲组1、补饲组2,每组20头,补饲组按试验方案进行早期补饲,对照组按传统饲养模式饲养,对比6月龄各项数据及试验牛母牛产后发情情况,进行分析总结。[结果]补饲组与对照组相比,犊牛生长发育效果差异显著,试验母牛产后恢复明显加快,产后90 d内发情母牛占比显著提高。[结论]科尔沁肉牛犊牛早期补饲更利于犊牛后期生长发育,促进母牛早发情提高繁殖能力,结合数据分析得出早期补饲至6月龄是更为适合科尔沁肉牛犊牛的饲养模式。[Objective] In order to explore the best feeding mode of Horqin beef calves, and provide theoretical reference for the promotion and popularization of early supplementary feeding of Horqin beef calves. [Method] 60 healthy Horqin calves with similar body shape and birth weight between 34 kg and 50 kg were selected and divided into control group, supplementary feeding group 1 and 2, with 20 calves in each group. The supplementary feeding groups were given early supplementary feeding according to the experimental scheme, while the control group was fed according to the traditional feeding mode. The data of 6 months old and the estrus situation of experimental cows were compared and analyzed. [Result] Compared with the control group, the growth and development of calves were significantly different, the recovery of experimental cows were significantly accelerated, and the proportion of estrous cows within 90 days after delivery was significantly increased. [Conclusion] Early supplementary feeding of Horqin beef calves was more conducive to the growth and development of calves at later stage, which promoted early estrus of cows and improved reproductive capacity. Combined with the data analysis, it was concluded that early supplementary feeding mode to 6 months old was more suitable for Horqin beef calves.
