Analysis On Concentrate Supplementary Feeding Effect Of Tibetan Sheep In Qinghai Province

Due to the change of season, temperature and pasture grass, the weight of Qinghai Tibetansheep grazing under natural conditions has dynamic changes one year.40only8-monthTibetan sheep lamb were selected randomly and divided into two groups: the natural grazinggroup as control and the natural grazing combined with natural grazing concentratesupplementary feeding as treated group. Each group had20sheeps. The experiment startedfrom August1to December31in2013. The weight of Tibetan sheep lamb in two groups weretested and at first day and15thday every month. Through determined experiment and dataanalysis, the determination of initial weight on August1in each group, natural grazing groupwas11.91±1.13kg, combined with the natural grazing concentrate feeding group was11.82±1.06kg, the difference was not significant (p>0.05). The final average weight wasmeasured on December31. The natural grazing group average terminal body weight was26.86±6.13kg. The natural grazing to concentrate supplementary feeding group averageterminal body weight was40.21±8.78kg. The sample average difference analysis, differenceis very significant (p <0.01). By analyzing the differences between average daily gain sampledifference is very significant (p﹤0.01). Our results showed Qinghai Tibetan sheep, in extraconcentrate supplementary feeding conditions, can play a better growth performance,especially under the condition of low temperature, won’t appear like natural grazing statusunder the weight of negative growth. Herdsmen make more156Yuan every sheep throughconcentrate supplementary feeding from August to December, compared with the naturalgrazing conditions. This has important guiding significance to solve the problem of the"return grazing land". As a result, it has great significance in the promotion of in livestockproduction.
