【摘要】：雞住白細(xì)胞蟲(chóng)病廣泛存在于雞產(chǎn)業(yè)化養(yǎng)殖中,危害非常大,發(fā)病率和死亡率居高不下,常給廣大的養(yǎng)殖戶帶來(lái)巨大的經(jīng)濟(jì)損失。本試驗(yàn)主要針對(duì)大田縣雞的養(yǎng)殖現(xiàn)狀,對(duì)大田縣雞住白細(xì)胞蟲(chóng)病進(jìn)行流行現(xiàn)狀調(diào)查。試驗(yàn)選取大田縣養(yǎng)雞比較集中6個(gè)鄉(xiāng)鎮(zhèn),根據(jù)不同的海拔高度和氣候;不同的飼養(yǎng)管理方式;不同的雞的品種等選取了 25戶養(yǎng)殖戶,每個(gè)養(yǎng)殖場(chǎng)隨機(jī)抽取20只雞進(jìn)行雞翅靜脈采血,制成血液涂片,觀察血液中的雞住白細(xì)胞蟲(chóng)的配子體。另外,每個(gè)場(chǎng)經(jīng)血涂片檢查確診的雞進(jìn)行解剖,臨床癥狀符合雞卡氏住白細(xì)胞蟲(chóng)病感染的基本特征。從而確診了大田縣雞住白細(xì)胞蟲(chóng)病是由卡氏雞住白細(xì)胞蟲(chóng)原蟲(chóng)引起的。根據(jù)調(diào)查顯示感染情況隨海拔由高到低呈遞減趨勢(shì);謝洋鄉(xiāng)和吳山鄉(xiāng)海拔較高,感染率分別為26.3%和19.2%,建設(shè)鎮(zhèn)海拔較低,感染率為12.5%。采用籠養(yǎng)的方式感染率低于散養(yǎng),籠養(yǎng)的感染率為5%,散養(yǎng)感染率為23.6%。本地雞的感染率低于外來(lái)雞品種,本地雞的感染率為15%,麻雞的感染率為24.7%。21-60日齡的雞屬于易感雞群,感染率為26.7%。本文立足于確保食品安全和減少藥物殘留為基本要求,夏秋季節(jié)到來(lái)時(shí),養(yǎng)殖戶要引起足夠的重視,采用預(yù)防為主,防治相結(jié)合的方針。產(chǎn)蛋雞盡量選用中草藥制劑,不用磺胺類藥進(jìn)行預(yù)防和治療。選擇養(yǎng)殖場(chǎng)盡量選擇地勢(shì)平坦,排水順暢的低海波地區(qū)養(yǎng)殖,如果條件允許的話,盡量采用籠養(yǎng)的方式。對(duì)雞舍周圍的環(huán)境定期消毒,消滅蟲(chóng)媒昆蟲(chóng),減少感染。
[Abstract]:Leucocytophthora disease is widely used in the industrialized breeding of chickens, which causes great harm, high morbidity and mortality, and often brings huge economic losses to the majority of farmers. Based on the current situation of chicken breeding in Datian County, the epidemic status of Leukocystis in Datian County was investigated in this experiment. According to different altitude and climate, different ways of breeding and management, different breeds of chicken, 25 households were selected in the experiment. Twenty chickens were randomly selected from each farm to collect blood from their wings, and blood smears were made to observe the gametophyte of white blood worms in the blood. In addition, the clinical symptoms of chicken confirmed by blood smear in each field were in accordance with the basic characteristics of Leukocystis infection in chickens. It was confirmed that Leukocystis disease in Datian County was caused by Leucocystis carinii. According to the investigation, the incidence of infection decreased with the elevation from high to low, the infection rate of Xie Yangxiang and Wushan Township was higher, the infection rate was 26.3% and 19.22.The altitude of Jianzhen town was lower, and the infection rate was 12.5%. The infection rate of cage culture was lower than that of rest culture. The infection rate of cage culture was 5 and 23. 6 percent respectively. The infection rate of local chickens was lower than that of exotic chickens. The infection rate of local chickens was 15. The infection rate of hens was 24.70.21-60 days old, and the infection rate was 26.7. This paper is based on the basic requirements of ensuring food safety and reducing drug residues. When the summer and autumn season comes, farmers should pay enough attention to it and adopt the policy of combining prevention with prevention. Laying hens choose Chinese herbal medicine as far as possible, do not use sulfanilamide for prevention and treatment. Select breeding farm as far as possible, flat terrain, smooth drainage of low sea wave breeding, if conditions permit, try to use cage culture. Periodically disinfect the surrounding environment of the chicken house, eliminate insect-borne insects and reduce infection.
