The Production Experiments Demonstration And Kit Technique Generalization Of The Mutton Sheep In Jiuquan

The growth of the mutton sheep production was rapid,which gradually become the focus of the well-being of rural industries and the new economic growth of Jiuquan in recent years.This study was carried out on the weight gain contrast experiment,different fattening(pasture and yard feeding)quomodoes on lamb production capability under conditions and the different medicine of synchronization of estrus processing and theartificial insemination contrast experiment of F1 among Suffolk♂×Small-Tail Sheep♀,Poll Dorset♂×Small-Tail Sheep♀,Small-Tail Sheep and Tibet hoodwinks the blood sheep in Jiuquan City,and chooses the best one at last.The results showed that the daily gain and feed conversion rate of F1(Suffolk♂×Small-Tail Sheep♀,Poll Dorset♂×Small-Tail Sheep♀) was significantly higher than that of Small-Tail Sheep,as well as the the crossbreeding heterosis and economic benefits;The daily gain,carcass weight,yield of carcass,meat percentage and the quality of mutton were higher in yard feeding sheep than those of the pasture sheep and had higher economic effect;PMSG was effect well in synchronization of estrus processing and conception rate was high.Based on the above study,this technology had been extended to the main agricultural and husbandry places of Jiuquan City.Now there are many households breeding the pure Small-Tail ewe,some breeding the mutton ram in order to supply the artificial insemination technology for nearby hourseholds,and some cultivating the F1,F2 commercial lambs which crossbred by Suffolk and Poll Dorset with Small-Tail sheep using the fresh sperm insemination technology.These lambs were ablactated 3 month-old and fattening 90 days for slaughter appears on market,the average body midsection reaches to a 18 kgs above.Through the implementation of the project,it effectively showed the region's resource advantage,fostered the growth of the livestock industry and enhanced local sheep production and technology.The farmers there have a new concepts on this and play a good model.And the effects of economic,social,the ecological are more significant,which will supply the important experience for the future of rural Mutton Sheep Industry development of Jiuquan,and even Gansu Province.
