【摘要】：鸡球虫病使鸡的生产效率降低,对家禽业特别是规模化养禽业危害严重。鸡球虫卵囊的生长和繁殖需经过无性生殖和有性生殖两个阶段,鸡球虫病在我国普遍存在,并且给养鸡业带来较大的经济损失。有养鸡的地方都是鸡球虫病的流行区。岳阳地区白羽肉鸡和蛋鸡的养殖量逐年增加,鸡球虫病给白羽鸡的养殖造成了一定的损失,笔者在岳阳地区选择了岳阳县、岳阳楼区、泪罗市、平江县4个调查点,采用临床检查、病理解剖、粪便检查等方式调查岳阳地区白羽鸡球虫病的流行情况。结果显示：白羽肉鸡岳阳县、汨罗市、平江县三个调查点鸡球虫病的感染率为2.87%、2.88%、2.79%,蛋鸡岳阳楼区、泪罗市两个调查点鸡球虫病的感染率为12.0%、12.24%。白羽肉鸡15-42日龄、蛋鸡60-80日龄发病率较高,每年的第1季度和第4季度为本病的高发期。根据调查山字球虫粉、百球清、新球特、球新四种抗球虫药的治愈率分别为90%、90%、60%和60%,通过试验,经疫苗免疫后使用抗球虫药物治疗的治愈率为95%,未经疫苗免疫直接使用抗球虫药物治疗的治愈率为85%。笔者总结分析了,自2009年至今岳阳地区白羽鸡防控鸡球虫病的经历的无需防控、药物治疗和疫苗免疫结合药物治疗的三个阶段的防治效果,提出加强饲养管理、保证足够长的空栏期、加强季节性管理等综合防治鸡球虫病的基本思路。
[Abstract]:Coccidiosis reduces the efficiency of chicken production and harms the poultry industry, especially the scale poultry industry. The growth and reproduction of chicken coccidiosis oocysts need to go through two stages of asexual reproduction and sexual reproduction. Coccidiosis is prevalent in China and brings great economic losses to the chicken industry. Where chickens are raised, they are endemic areas for chicken coccidiosis. The breeding quantity of white feather broiler and laying hens in Yueyang area increased year by year, and coccidiosis caused certain losses to the breeding of white feather chickens. The author chose four investigation points in Yueyang County, Yueyang Lou District, Yiluo City, Pingjiang County. Clinical examination, pathological anatomy and fecal examination were used to investigate the prevalence of coccidiosis in Yueyang area. The results showed that the infection rate of coccidiosis was 2.87 and 2.88 in Yueyang County, Miluo City and Pingjiang County. The infection rate of coccidiosis was 12.0% and 12.24% in Yueyang Lou District and Yililuo City. The incidence rate of white broiler was 15-42 days old and that of laying hens 60-80 days was higher. The first and fourth quarter of each year was the high incidence period of the disease. According to the investigation, the cure rates of the four kinds of anticoccidists, such as the powder of coccidiosis, Baizhuqing, Xinzhoute and Buxingxin, were 90% and 60%, respectively, and passed the experiment. The cure rate of anticoccidial drug was 95% after vaccination, and 85% by direct anticoccidial drug therapy without vaccine immunization. The authors summarized and analyzed the effects of three stages of prevention and control of coccidiosis of white feather chickens in Yueyang area from 2009 to now, which included no prevention and control, drug therapy and vaccine immunotherapy combined with drug therapy, and proposed to strengthen the management of feeding. To ensure long enough empty period, strengthen seasonal management and other integrated control of chicken coccidiosis basic ideas.
