摘要:

为了解规模化舍饲湖羊消化道寄生虫感染情况,本研究应用饱和蔗糖溶液漂浮法、饱和盐水漂浮法、卢戈氏碘液染色法、离心沉淀法和麦克马斯特氏计数法等对采自河南部分地区规模化全舍饲湖羊养殖场共计553份粪便样品进行了调查。调查结果显示:寄生虫总感染率高达97.47%,75.23%的样品混合感染,样品混合感染的寄生虫种类最多为5种;共查到球虫、隐孢子虫、贾第虫、阿米巴、鞭虫、圆线虫和绦虫7种寄生虫,感染率分别为90.42%、0.90%、4.88%、65.64%、12.48%、42.13%和4.88%;感染强度最大的为球虫,每克粪便的卵囊数(OPG)最高达652 000,其次为圆线虫,每克粪便的虫卵数(EPG)最高为7 000;湖羊消化道寄生虫感染无明显的年龄、性别差异(P>0.05);季节流行动态显示,春、夏、秋三季的寄生虫感染率与冬季相比有较大差异。以上结果说明,湖羊消化道寄生虫感染较为普遍,应采取有效的综合防控措施,以保障羊群的健康发展。

Abstract:

To know the prevalence of gastrointestinal parasites in Hu sheep from stall-feeding farms,a total of 553 fresh fecal samples from part stall-feeding farms in Henan were collected and examined the presence of eggs or oocysts using centrifugation method,saturated salt solution floatation technique,Sheather's sugar flotation technique,Lugol's iodine-solution staining method and McMaster's method.The results showed that the overall infection rate of gastrointestinal parasites was as high as 97.47%,and 75.23% of the samples were mixed infection,samples mixed infections with up to 5 species of parasites.A total of 7 species of parasites,Coccidia,Cryptosporidium,Giardia,Amoeba,Whipworm,Nematode and Moniezia were found to be 90.42%,0.90%,4.88%,65.64%,12.48%,42.13% and 4.88%,respectively.The highest infection intensity was Coccidia,and its highest number of oocysts per gram(OPG) of feces was 652 000,followed by Nematode,and the highest number of eggs per gram (EPG) of feces was 7 000.There was no significant age and gender difference in infection rate of gastrointestinal parasites in Hu sheep (P>0.05).The seasonal epidemic dynamics showed that the parasitic infection rates in spring,summer and autumn were different from those in winter.In conclusion,parasitic infections in the digestive tract of Hu sheep were more common,and effective comprehensive prevention and control measures should be taken to ensure the healthy development of the flock.
