中文摘要:

      [目的]为调查云岭牛肠道寄生虫的感染情况,以其提供有效的防治措施。[方法]从小哨云岭牛核心育种场和楚雄锦达牧业扩繁场采集382份新鲜粪便样品,采用饱和盐水漂浮法和自然沉淀法检测寄生虫感染情况。[结果]共检测出89份样品存在寄生虫感染,平均感染率为23.30%。分别检出了线虫、球虫和吸虫的感染,其感染率分别为17.28%、7.07%、0.26%,混合感染率为1.31%。云岭牛核心育种场寄生虫感染率为31.25%,楚雄锦达牧业扩繁场为15.26%；自由放牧云岭牛寄生虫感染率为36.05%,圈养云岭牛为19.59%；不同养殖场、不同养殖方式的云岭牛之间寄生虫感染存在极显著差异(P<0.01),而不同性别和年龄的云岭牛之间无显著性差异(P>0.05)。[结论]云岭牛寄生线虫感染较为突出,应加强综合防治以促进肉牛养殖业的健康可持续发展。

英文摘要:

      【Objective】The aim of this study was to investigate the infection of intestinal parasites in Yunling cattle for providing effective control measurements.【Methods】382 fresh feces samples were collected from Nucleus Herd on Xiaoshao Farm and Jinda Muye Multiplier Herd in Chuxiong city to investigate the parasite infection by the saturated salt water floating method and natural precipitation method .【Result】89 samples were detected to infect parasite, with an average infection rate of 23.30%. Nematode, coccidia and fluke were detected, with an infection rate of 17.28%, 7.07%, and 0.26%, respectively; the mixed infection rate was 1.31%. There was a parasite infection rate of 31.25% in Yunling Nucleus Herd, 15.26% in Jinda Muye Multiplier Herd, 19.59% in penning and 36.05% in freely grazing for Yunling cattle. There were significant differences from parasite infections in the different farms and feeding system (P<0.01), but there was no significant difference from the different genders and ages in Yunling cattle (P>0.05). 【Conclusion】The results showed that the parasitic nematode infection in Yunling cattle was serious. Therefore, some comprehensive prevention and control measurements should be strengthened to promote further healthy and sustainable development for beef industry.
