Coccidiosis is an important enteric parasitic disease of poultry associated with significant economic losses to poultry farmers worldwide. This survey was conducted from June 2014 through July 2015 with the main goal of investigating the prevalence and associated risk factors of coccidiosis among village and exotic breeds of chickens in Maiduguri, Northeastern Nigeria.
A total of 600 fecal samples from live and slaughtered birds comprising 284 young, 141, growers and 175 adult birds; 379 male and 221 female birds; 450 exotic and 150 local breeds of birds were randomly collected either as bird's fresh droppings or cutting open an eviscerated intestine of slaughtered birds, while noting their age, sex, and breeds. Samples were analyzed using standard parasitological methods and techniques.
An overall prevalence rate of 31.8% (95% confidence interval: 28.07-35.52) was obtained. Higher prevalence rates were recorded in growing birds 58.9% (50.78-67.02), female birds 35.3% (29.00-41.60), exotic birds 42.4% (37.83-46.97), and broiler birds 68.7% (61.28-76.12). Similarly, higher infection rates were also observed among birds sampled from Mairi ward 66.7% (56.03-77.37), intensive management system 46.5% (41.61-51.39), and constructed local cages 54.0% (46.02-61.98). The difference in prevalence of coccidiosis among age groups, breeds, among exotic breeds, sampling sites, husbandry management systems, and litter management systems was statistically significant (<0.0001). However, no significant difference (p>0.05) of infection rates was observed in sex.
Coccidiosis is endemic in both commercial and backyard poultry farms in Maiduguri due to poor management practices encouraging Eimeria oocysts build-up. It is therefore, recommended that poultry farmers should practice strict biosecurity measures on their farms, creating awareness on the prevalence of coccidiosis, routine vaccination against coccidiosis and educating poultry farmers on the need for maintaining good hygienic standards and good flock health management.
球虫病是家禽重要的肠道寄生虫病,给全球家禽养殖户造成重大经济损失。本次调查于2014年6月至2015年7月进行,主要目的是调查尼日利亚东北部迈杜古里乡村鸡和外来品种鸡的球虫病患病率及相关风险因素。
共随机采集600份来自活禽和屠宰禽的粪便样本,其中包括284只幼禽、141只育成禽和175只成年禽;379只雄禽和221只雌禽;450只外来品种禽和150只本地品种禽,样本采集方式为收集禽新鲜粪便或切开屠宰禽的内脏肠道,同时记录其年龄、性别和品种。样本采用标准寄生虫学方法和技术进行分析。
总体患病率为31.8%(95%置信区间:28.07 - 35.52)。育成禽患病率较高,为58.9%(50.78 - 67.02);雌禽为35.3%(29.00 - 41.60);外来品种禽为 42.4%(37.83 - 46.97);肉鸡为68.7%(61.28 - 76.12)。同样,从迈里区采集的禽样本感染率较高,为66.7%(56.03 - 77.37);集约化养殖系统中的禽为46.5%(41.61 - 51.39);建造的本地鸡笼中的禽为54.0%(46.02 - 61.98)。球虫病在不同年龄组、品种、外来品种之间、采样地点、饲养管理系统和垫料管理系统中的患病率差异具有统计学意义(<0.0001)。然而,性别间感染率无显著差异(p>0.05)。
由于管理不善导致艾美耳球虫卵囊积聚,球虫病在迈杜古里的商业和家庭养禽场中均为地方病。因此,建议家禽养殖户在其养殖场实施严格的生物安全措施,提高对球虫病患病率的认识,进行球虫病常规疫苗接种,并教育家禽养殖户保持良好卫生标准和良好禽群健康管理的必要性。
