Two outbreaks of parasitic gastroenteritis were observed in a group of 10 first-season grazing calves, one in mid-July and one in mid-September. In both cases emergency anthelmintic treatment was needed to prevent further damage. Severe clinical signs were observed together with high faecal egg counts and high serum pepsinogen and gastrin concentrations. Low total protein and albumin concentrations were also observed, especially during the second outbreak. The ostertagia antibody levels followed a similar pattern to the serum pepsinogen and gastrin concentrations. At the end of the housing period a mild type II ostertagiasis was observed. In the second grazing season the heifers did not show any signs of parasitic gastroenteritis, but there was a serious outbreak of husk which required treatment.
在一组10头首季放牧的犊牛中观察到两起寄生虫性肠胃炎疫情，一起发生在7月中旬，另一起在9月中旬。在这两起疫情中，都需要进行紧急驱虫治疗以防止进一步损害。观察到严重的临床症状，同时粪便虫卵计数高，血清胃蛋白酶原和胃泌素浓度高。还观察到总蛋白和白蛋白浓度低，尤其是在第二次疫情期间。奥斯特他线虫抗体水平与血清胃蛋白酶原和胃泌素浓度呈现相似模式。在圈养期结束时，观察到轻度II型奥斯特他线虫病。在第二个放牧季节，小母牛未表现出任何寄生虫性肠胃炎迹象，但发生了一次严重的牛肺线虫病疫情，需要进行治疗。
