Xinjiang is one of China 's five major pastoral areas , put shepherd parasite disease a wide range of serious problems the development of the sheep industry in Xinjiang . Invasion of gastrointestinal parasites of sheep extensive and widespread, long-term invasion by the parasite , resulting in the adverse reaction of the animal body tissues , such as the consumption of nutrition and tissue injury led to the decline in animal performance , feed utilization decreased , the products reduce the number of , the quality is not high . Invasion of parasitic diseases also cause the young lambs reduced immunity , plus feeding mismanagement will cause the sheep and a large number of deaths , bring direct and indirect economic losses to livestock production is very serious . Put the shepherd 900 Bole investigation gastrointestinal parasite infections were detected in 20 stud gastrointestinal parasites , including 13 kinds of nematodes that Yip Shadbolt nematodes , sheep Yangkou nematodes , Gansu Oesophagostomum , the serpentine hair Park nematodes , Albright Ostertagia , Mongolia and Marshall nematode , Haemonchus nematodes thorns like the narrow neck nematodes , Dictyocaulus filaria the Korotkoff original park nematodes , sheep narrow neck nematodes , the first sheep wool The nematode Steinernema hair first nematode . Tapeworm four kinds , namely expansion Moniezia Bayesian Moniezia , narrow neck Cysticercus and Echinococcus granulosus . Flukes three kinds , that spear -shaped double-lumen flukes Fasciola , deer, front and rear disc flukes. The advantages of insect species detected the spear shaped double-lumen flukes , Albright Ostertagia , Haemonchus contortus and sheep the Yangkou nematode infection rate reached 29.1% , 27% ??, 26.4% and 25% , respectively . Bole put the findings of the shepherd gastrointestinal parasites infection , as well as the popular rule of sheep gastrointestinal nematodes , we change the deworming deworming will fall 8 to September each year changed to early December , before the advent of spring adult climax a winter's day deworming . Use of broad-spectrum the efficient biological deworming drugs worming , both the hindered type larvae can get rid of the body , they can get rid of infective larvae , resulting in an overall block 3 to May adults climax formation . Spring and lack of early winter deworming can effectively control the sheep died, reduce ewe abortion due to parasitic disease caused production ewe breeding survival rate , so as to achieve the purpose of improve discharge shepherd production performance and economic benefits . The test for the Bo the state to develop a reasonable , effective shepherd deworming program to provide a reliable scientific basis .
