【摘要】：为了了解林牧公司羊群寄生虫感染情况,并针对性地驱虫,提高羊群的健康度,本课题对林牧公司羊群的1200只山羊进行调查,健康羊有562只,不健康羊有638只。从1200只羊的粪便中,检出带线虫的粪便数为180份,线虫感染率为15%；检出带吸虫粪便数为36份,吸虫感染率为3%；检出带绦虫粪便数为24份,绦虫感染率为2%；蠕虫感染率总共为18%(216/1200)。检出带球虫粪便数为638份,球虫感染率为53%(638/1200)。抽取256只不健康羊,分为断奶羊组、育肥羊组、种母羊组、种公羊(公羊)组,每组64只,直肠取粪便256份,用直接涂片法、碘液染色法、饱和盐水漂浮法、离心沉淀法检查粪样。断奶羊组检出带球虫和线虫的粪样分别为61份和6份,球虫感染率、线虫感染分别为95.3%(61/64)和9.4%(6/64)；育肥羊组检出带球虫和线虫的粪样分别为58份和11份,球虫感染率、线虫感染分别为90.6%(58/64)和17.2%(11/64)；种母羊组检出带球虫和线虫的粪样分别为59份和8份,球虫感染率、线虫感染分别为92.2%(59/64)和12.5%(8/64)；种公羊(公羊)组检出带球虫和线虫的粪样分别为59份和11份,球虫感染率、线虫感染分别为92.2%(59/64)和17.2%(11/64)。从检查结果可以看出,林牧公司羊群球虫感染率比线虫感染率高。断奶羊组、育肥羊组、种母羊组、种公羊(公羊)组分别用痢宁溶液、痢宁溶液和伊力新注射液、磺胺喹嗯啉钠粉剂和痢宁溶液、磺胺喹嗯啉钠粉剂进行驱虫,驱虫后各组球虫感染率均降低,断奶羊组降低了17.2%,育肥羊组降低了1.5%,种母羊组降低了87.5%,种公羊(公羊)组降低了1.6%,驱球虫结果表明,磺胺喹嗯啉钠粉剂与痢宁溶液联合应用效果与痢宁溶液、伊力新注射液和痢宁溶液联合应用、磺胺喹嗯啉钠粉剂相比有显著差异(p0.01)。驱虫后各组线虫感染率变化无规律,断奶羊组为17.2%(驱虫前9.4%),育肥羊组为7.8%(驱虫前17.2%),种母羊组为10.9%(驱虫前12.5%),种公羊(公羊)组为9.4%(驱虫前17.2%)。
[Abstract]:In order to understand the infection of herding parasites in forestry and animal husbandry companies and to improve the health of sheep, 1200 goats were investigated in this paper. There were 562 healthy sheep and 638 unhealthy sheep. From the feces of 1200 sheep, 180 cases of nematodes were detected, the infection rate of nematode was 15; the number of feces with paragonimiasis was 36, the infection rate of paragonimiasis was 3; the number of faeces of Taenia solium was 24, the infection rate of tapeworm was 22.The total infection rate of worm was 1816 / 1200. The number of feces with coccidiosis was 638, and the infection rate of coccidia was 5338 / 1200. 256 unhealthy sheep were selected and divided into weaning group, fattening group, ewe group and male sheep (ram) group with 64 in each group. 256 feces were collected from rectum, followed by direct smear method, iodine staining method and saturated saline floating method. The feces were examined by centrifugal precipitation method. The fecal samples of coccidiosis and nematode were 61 and 6, respectively. The infection rate of coccidiosis and nematode were 95.31- / 64) and 9.4x / 64, respectively, and the feces samples of coccidiosis and nematode were 58 and 11, respectively, and the infection rate of coccidiosis was found in the fattening sheep group. The number of feces with coccidia and nematodes were 90.6% 58 / 64 and 17.2 / 64, respectively, and 59 and 8 feces with coccidiosis and nematodes were detected in ewe group, respectively. The number of feces with coccidia and nematode were 59 and 11, respectively. The infection rate of coccidiosis and nematode infection were 92. 2 / 59 / 64 and 92. 2% / 59 / 64 and 17. 2% / 64 respectively. The results showed that the infection rate of herd coccidiosis was higher than that of nematodes. Weaning sheep group, breeding fattening sheep group, breeding sheep group and breeding ram group (ram) group were treated with Lining solution, Lining solution and ilisin injection, sulfamethrin sodium powder, sulfaquinoline sodium powder, and sulfamethrin sodium powder, respectively. After deworming, the infection rate of coccidiosis in all groups decreased, the weaning group decreased 17.2%, the fattening sheep group decreased 1.5 and the breeding ewe group decreased 87.5%, and the breeding ram (ram) group decreased 1.6%. There was significant difference between sulfaquinoline sodium powder and sulfaquinoline sodium powder as compared with that of lixigenin solution, ilexin injection and triamcinol solution, compared with sulfaquine sodium powder (P 0.01). There was no regular change of nematode infection rate in each group after insect repellent. The infection rate of weaning sheep was 17.2 (before insect repellent 9.4%), that of fattening sheep was 7.8 (before insect repellent 17.2g), that of breeding ewe was 10.9 (first 12.5%) and that of male sheep (ram) was 9.4 (17.2g before insect repellent).
