摘要
以饲料和土壤低磷、高氟、低硒为线索,检测跛行黄牛血清中碱性磷酸酶(ALP)、羟脯氨酸(HYPRO)、维生素D以及甲状旁腺素(PTH)等钙、磷代谢的相关指标的动态变化,探讨低磷、高氟、低硒对黄牛骨骼和肌肉的影响,以及这些致病因素之间的相互关系,为黄牛跛行病的病因学诊断和防治提供依据。结果显示:(1)土壤和饲料低磷,导致黄牛血清低磷及钙磷比例失调是引起黄牛跛行的直接因素。(2)土壤、饲料高氟是加重钙磷代谢障碍引发跛行的主要因素。(3)黄牛硒缺乏导致的肌肉损伤,是引发跛行的并发因素。
Lameness in yellow cattle occurred at a farm in Jilin province was investigated by detecting the concentrations of P ,F and Se in soil and forage from the diseased farm and the serum concentrations of Ca ,P ,F ,Se ,PTH ,CT ,Hypro, ALP ,VD, DHCC in lameness cattle. The results showed： （1）The low-level phosphorum in feed and soil may be the immediate etiological factor of cattle lameness; （2）High level F in feed and soil was the main pathogenic factor of it. （3）Muscular iniury caused by selenium deficiency was the complicated factor.
