【摘要】 鸡球虫病是由艾美尔属球虫引起的鸡的肠道疾病。该病在我国大多数的养鸡场都有分布,对养鸡业的危害很严重,由于衡阳地区湘黄鸡的养殖大多采用地面平养,极易导致球虫病的感染,给广大养鸡户带来了很大的经济损失。本文作者选取衡阳市湘黄鸡饲养较集中的沿湘江流域的衡东,衡山,衡南,衡阳县以及衡阳市郊区五个县区的采用地面散养方式的专业养鸡户,通过调查问卷和现场诊断、剖检及粪便虫卵检查等措施,调查了7个养鸡场的球虫感染率,结果显示衡阳地区湘黄鸡的鸡球虫感染率为100%,发病率10～85.5%。死亡率从1.5～22%不等,其中15～35日龄的雏鸡发病率和死亡率最高。为更好地防治湘黄鸡球虫病提供了重要的数据。通过将所调查鸡场的粪样分段采集,用琼脂薄板进行单卵囊的分离培养和球虫单卵囊感染试验后鉴定发现,衡阳地区湘黄鸡感染的主要鸡球虫种类有:巨型艾美尔球虫(E.maxima)、柔嫩艾美尔球虫(E.tenella)、堆型艾美尔球虫(E.acervulina)、早熟艾美尔球虫(E.praecox)和毒害艾美尔球虫(E.necatrix)五种。作者通过采用疫苗与中草药相结合防治鸡球虫的方法与单纯用疫苗、中药或西药的方法进行对比,发现疫苗加中药进行绿色防治人工感染鸡球虫病取得理想效果。疫苗与中草药相结合的方法能使鸡感染球虫后的成活率为100%,并且使鸡的成活率和相对增重率分别达到100%与99.8%,抗球虫指数为189.3。并随后在3个鸡场共7800羽进行了推广试验,也取得了明显效果。说明采用疫苗加中药的方法是目前防控鸡球虫的较为理想的方案。更多还原

【Abstract】 Chicken coccidiosis is a intestinal disease caused by the Eimeria coccidiosis.The disease has distributing at most of the farms in our country,it has very serious harmful to the poultry industry And as most of the farm dependent on the surface,easily infection of coccidiosis,for majority of Chicken farmers has led to great economic losses.Author selected the surface of free-range chicken farming households rearing more concentrated along the east、Hengshan、south、Hengyang County and Hengyang outskirts on the Xiang River basin,through the questionnaire diagnosis or autopsy and exam of worm’s egg in faeces,investigated the coccidia infection rate in 7 farm,the results show that the yellow chicken coccidia infection rate of 100%,the morbidity rate is 10～85%and the death rate is 1.5～22%,mainly 15 to 35-day-old chicks of morbidity and The highest mortality rates in Hengyang area.In order to better prevention and treatment Hunan chicken coccidiosis provide important data.Through investigated the sub-collecting fecal samples in the farm,one of oocysts isolation、culture and single-coccidia oocysts infection,found that Hengyang area of the main xianghuang chickens infected with coccidia have:E.maxima、E.tenella、E.acervulina、E.praecox and E.necatrix.The author through contrast of Chinese herbal medicines and vaccines combined with the simple use of vaccines,medicine or western medicine methods,found the vaccine and prevention and treatment of the population infected with green plot tenella Disease desired effect.The survival rate can achieve to 100%when coccidia infected chicken used the herbal medicine and vaccine combination to treated,and the survival rate of weight gain and relative rate of 100%and 99.8%,the anticoccidial index is 189.3.Use of the traditional Chinese medicine and vaccine can inhibit the coccidia growth of chicken.更多还原
