Abstract


Jiuquan City Sheep production momentum of rapid development in recent years , becoming the focus of Jiuquan City, a well-off construction industry and rural economy a new growth point . Poll Dorset sheep and Small Tail Han sheep hybrid generation , Han sheep and Tibetan Mongolian mestizo sheep as the research object , Suffolk Small Tailed Han hybrid generation hybrid sheep weight gain comparative experiments in Jiuquan City , feeding grazing mutton production performance under different fattening way different drugs estrus synchronization treatment temperature the fine granted with contrast test . The results show that : Sa cold hybrid generation Tao cold the hybrid generation ADG , feed conversion ratio were significantly higher than the Han sheep, obvious heterosis , significant economic benefits; yard feeding sheep ADG , carcass weight, dressing percentage , Jingrou were higher than put the shepherd , and high economic returns ; pregnant mare serum gonadotropin treatment Small Tailed Han sympathy estrus effect , high conception rate . On the basis of the above findings , under the jurisdiction of Suzhou , urn , Yumen , Anxi , Dunhuang , Jiuquan City , five agricultural counties and Subei , Aksay 2 the animal husbandry County 's 50 townships application supporting technology promotion . Small Tail Han sheep foundation ewes pure fan - based Small Tail Han sheep purebred breeding households ; ram mainly to the breeding of improved varieties of meat and radiation for the surrounding farmers to carry out the fresh semen grant sheep diluted semen breeding work with families ; Small Tailed Han breeding and F1 foundation ewes mainly through the diluted semen breeding technology , production Tao cold , and Bodhisattva cold F1 generation Crossbred lamb production of household commodities . The F1 generation commodity lambs weaned at 3 months of age , after 90 days of fattening in shed slaughter slaughter market, the average carcass weight of 18kg or more . Sheep hybrid test and supporting technologies to promote effectively play the advantage of the region 's resources , and fostering the growth of the livestock industry leading industries , make supporting local sheep production and technology , the sheep has been greatly improved , the concept of aquaculture farmers a larger change played a good demonstration and promotion , economic, social , ecological effectiveness are more significant for the future Jiuquan even rural Gansu Province sheep industry development experience .
