摘要
[目的]提高藏绵羊哺乳期羔羊的补饲效果。[方法]采用单因子设计,探讨藏绵羊哺乳期羔羊的早期补饲培育模式。[结果]在放牧和补饲粗饲料相同的条件下,同时补饲代乳粉＋全价料对藏绵羊哺乳期羔羊的补饲效果明显好于单独补饲玉米或全价料,日增重差异显著（P〈0.05）或极显著（P〈0.01）。在有效补饲条件下藏绵羊羔羊生长发育迅速,早期平均日增重可达到140~160 g/d,羔羊成活率可达到93.75%。[结论]合理搭配羔羊代乳粉＋全价料是藏绵羊哺乳期羔羊早期补饲培育的优化模式。
[ Objective ] The research aimed to improve the supplementary feeding effects of Tibetan sheep Iambs in lactation period. [ Method ] Using single factor design, the early supplementary feeding model of Tibetan sheep lambs in lactation period was explored. [ Result ] Under the same conditions of grazing and supplementary feeding of roughage, the supplementary feeding effects of simultaneous supplementary feeding of milk replacer and complete feed on Tibetan sheep Iambs in lactation period were better than that of supplementary feeding of maize or complete feed singly, the differences of daily weight gain were significant（ P 〈 0.05 ） or extremely significant（ P 〈 0.05 ）. Under the condi- tions of effective supplementary feeding, Tibetan sheep lambs grew fast, the average daily weight gain in early period reached 140 - 160 g/d, and the survival rate of lambs reached 93.75%. [ Conclusion] The optimum model of early supplementary feeding of Tibetan sheep lambs in lactation period was appropriate proportion of milk replacer and complete feed of lambs.
