Abstract

Backyard poultry production are considered as sources of meat and egg production. However, Parasites are among the main pathogenic agents, threatening the health of poultry and poultry products. The current study was conducted to investigate the prevalence of ectoparasite of poultry managed under backyard system started from November 2019 to April 2020 in Bishoftu town, surroundings of four kebeles; Babogaya, Danbi, 01kebele and 05 kebele in Oromia region South east of Finfinnee. 384 chickens of different age groups, both sexes and breeds were examined. Overall, 228/384 (59.4%) of chickens were infested with species of ectoparasites that mainly grouped into lice 141(36.7%), flea 79 (20.6%), and mite 8(2.1%). The prevalence of ectoparasite infection was 56(14.6%), 51(13.3%), 58(15.1%) and 63(16.4)% in Bishoftu town, Babogaya, Danbi, 01kebele and 05 kebele respectively, the difference in the prevalence of the parasites among difference kebeles were not statistically significant (P>0.05). The prevalence of ectoparasites infestation was higher in male 128(33.33%) chickens than females 100(26.04%) and higher in adult 150 (39.1%) than young chicken 78 (20.3%), high in local breeds 129(33.6%) than exotic breed 99 (25.8%). Seven species were identified with their attachments site, namely; menacanthus stremineus(13.3%) was found on skin, menopon gallinae(12.5%) was found on skin, thigh, feather and breast, goniodes gigas(5.5%) was found on skin and body feather, gonicotes gallinae (2.9%) was found on feather, lipeurus caponus(2.6%) was found on wing, skin, tail feather and a single species of flea(Echidnophaga gallinacae) 20.6% was found on eye, comb and wattle. while a single species of mite (ornithonyssus sylviarum) 2.1% was found on base of feather particularly, the vent area. In conclusion, infestation of chicken with ectoparasites was important constraint in poultry production sector. Associated with lack of attention with respect to hygienic system, treatment and control practices. Based on the results it could be suggested that, good management, biosecurity and the education of farmers could be a vital measure to keep free from ectoparasites and improve the productivity of the chicken.
埃塞俄比亚Bishoftu镇影响后院鸡的主要Ecto寄生虫调查
后院家禽生产被认为是肉和蛋生产的来源。然而,寄生虫是主要病原体之一,威胁着家禽和家禽产品的健康。本研究调查了2019年11月至2020年4月在比绍图镇4个鸡舍周围的后院系统管理的家禽外寄生虫的流行情况;选取芬兰东南部奥罗米亚地区的Babogaya、Danbi、01kebele和05 kebele,共384只不同年龄、性别和品种的鸡。总共有228/384只(59.4%)鸡被体外寄生虫感染,主要有虱141种(36.7%)、蚤79种(20.6%)、螨8种(2.1%)。毕肖图镇、巴布加亚、丹比、01kebele和05 kebele的体外寄生虫感染率分别为56(14.6%)、51(13.3%)、58(15.1%)和63(16.4%)%,不同kebele间寄生虫感染率差异无统计学意义(P < 0.05)。雄鸡128(33.33%)比雌鸡100(26.04%)高,成鸡150(39.1%)比雏鸡78(20.3%)高,地方品种129(33.6%)比外来品种99(25.8%)高。鉴定出附着物位置的有7种,分别为;在皮肤、大腿、羽毛和乳房上发现了鸡翅翅螨(13.3%),在皮肤和体毛上发现了鸡翅翅螨(12.5%),在羽毛上发现了鸡翅翅螨(2.9%),在翅膀、皮肤和尾羽上发现了鸡翅翅螨(2.6%),在眼睛、梳子和鸡冠上发现了鸡翅翅蚤(20.6%)。鸟类螨(ornithonyssus sylviarum) 1种,占2.1%,主要分布在羽毛基部,尤其是气孔区。综上所述,鸡体外寄生虫感染是制约家禽生产的重要因素。与缺乏对卫生系统、治疗和控制措施的重视有关。结果表明,良好的管理、生物安全措施和对养殖户的教育是防治鸡体外寄生虫和提高鸡产量的重要措施。
