Protein supplementation improves the resistance of sheep to haemonchosis. This experiment investigated the Scottish blackface breed to establish whether dietary protein supplementation is still beneficial in a genetically resistant breed. Lambs were given either a basal diet or a diet supplemented with soyabean meal to give an additional 80 g crude protein kg dry matter-1. The lambs were given an initial loading dose of Haemonchus contortus, followed by a trickle infection for 10 weeks. The weight gains of the lambs given the supplemented diet were greater and their carcases were leaner, irrespective of infection status. Infected animals on the basal diet were more anaemic and hypoalbuminaemic than animals receiving the supplemented diet, although there were no statistically significant differences in mean worm burdens or faecal egg counts.
补充蛋白质可提高绵羊对血矛线虫病的抵抗力。本实验以苏格兰黑脸羊品种进行研究，以确定在具有遗传抗性的品种中，补充膳食蛋白质是否仍然有益。给羔羊分别提供基础日粮或补充豆粕的日粮，以使每千克干物质额外含有80克粗蛋白。给羔羊最初接种一定剂量的捻转血矛线虫，随后进行为期10周的持续感染。无论感染状况如何，补充日粮的羔羊体重增加更多，其胴体更瘦。基础日粮组的感染动物比补充日粮组的动物贫血更严重且白蛋白水平更低，尽管平均虫负荷或粪便虫卵计数没有统计学上的显著差异。
