Serum pepsinogen estimations from serially bled lambs grazing on pasture from spring to autumn showed correlations with the availability of Ostertagia larvae on pasture, with faecal egg counts of O circumcincta, and with Ostertagia worm counts in similar lambs slaughtered fort-nightly from the same pasture. In the slaughtered lambs correlations were recorded between worm count, serum pepsinogen level and abomasal pH. The value of serum pepsinogen estimations as a diagnostic test is discussed with reference to these findings.
对从春季到秋季在牧场放牧的羔羊进行连续采血并测定血清胃蛋白酶原，结果显示其与牧场上奥斯特他线虫幼虫的可获得性、环形奥斯特他线虫的粪便虫卵计数以及从同一牧场每两周宰杀的相似羔羊体内奥斯特他线虫的虫体计数相关。在宰杀的羔羊中，记录到虫体计数、血清胃蛋白酶原水平与皱胃pH值之间的相关性。参照这些研究结果，对血清胃蛋白酶原测定作为一种诊断检测方法的价值进行了讨论。
