The Study On Performance Of Sheep Affected In The Condition Of Confinedness

In order to provide beneficial reference to the development of mutton sheep and cashmere goat in Jilin province, this paper incorporate with the practical development of sheep in Jilin province, difference of reproduction rate, daily gain, abatage rate , and the rate of meat are analysised in confinedness condition among the different cross combination, and the transmutation of performance between the condition of confinedness with the condition of grazing, is analysised by the determination of feeder category ,constitution , and fibres growth, et al.The results of experiment one that is the influence of performance of Liaoning cashmere goat in the condition of confinedness showed as follows:The feeder category in the condition of confinedness is fewer than that in the condition of grazing.There is increasing tendency that is the body weight of majoring ram and ewe, the body weight of ram increase 0.92%, and it of ewe increases 0.98%.There is increasing tendency that is the fibers length of majority ram and ewe, it increase 3.64% of ram and increase 6.20% of ewe.There is thickening tendency that is the fibers fineness of majority ram and ewe, it increase 2.53% of ram and increase 0.34% of ewe.There is increase tendency that is the fibers production of majority ram and ewe, it increase 0.03% of ram and increase 3.73% of ewe, but about pure fiber rate ,it increase 3.10% of ram and increase 2.04% of ewe.The results of experiment two that is the influence among different cross combination s performance in the condition of confinedness showed as follows:There is difference of breeding coefficient among different cross combination .The cross bombination of German mutton merino with Small tail han sheep >Texel with Small tail han sheep>Polled dorst with Small tail han sheep.There is difference of growth performance among different cross bombination ,the daily gain from birth to weaning , the cross bombination of German mutton merino × Small tail han sheep>Texel × Small tail han sheep > Polled dorst × Small tail han sheep , it means that the cross bombination of...
