摘要
[目的]为了探索早期补饲对规模养殖条件下平凉红牛犊牛体重发育的影响,[方法]选取分娩日期接近的妊娠母牛18头,分为试验组和对照组,早期补饲试验组犊牛,分析各月龄体重数据。[结果]结果表明在规模化养殖条件下,与传统养殖方式相比,对平凉红牛犊牛采取早期补饲,犊牛在3月龄到6月龄时体重差异显著(P<0.05)。[结论]因此,在实际生产中应重视犊牛早期的隔栏补饲工作,有利于提高肥牛生产效率和经济效益。
[Objective]In order to explore the effect of early supplementary feeding on the weight development of Pingliang Red Cattle calves under large-scale breeding conditions.[Methods]Eighteen pregnant cows with close delivery dates were selected and divided them into experimental group and control group,the weight data of each month after supplementary feeding of calves in the experimental group were analyzed.[Results]The results showed that under the conditions of large-scale breeding,the weight from 3 months to 6 months of age of Pingliang red calves,there was significant difference between traditional breeding methods and early supplementary feeding(P<0.05).[Conclusion]Therefore,in actual production,the early stall supplementary feeding of calves should be paid special attention to,which is beneficial to improve the production efficiency and economic benefits of beef cattle.
