Study on the Early Supplementary Feeding Model of Tibetan Sheep Lambs in Lactation Period
[Objective] The research aimed to improve the supplementary feeding effects of Tibetan sheep lambs 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 lambs 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 conditions 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.
