The general practice of sheep farmers in gastrointestinal helminth control is based on the use of commercial drugs, making chemoresistance very common. Considering this, our study focused on the biological control of gastrointestinal parasitism using high-tannin plant hay. Three groups of 30 animals each were formed. The control group was additionally fed meadow hay, while the other two groups received chicory (group 2) and bird's foot trefoil hay (group 3). The number of gastrointestinal strongyle eggs, shed through faeces (EPG), was surveyed for 28 days for all animals. The amounts of total tannins for meadow, chicory, and hay supplements were 13.92 mg/g, 78.59 mg/g, and 94.43 mg/g, while their condensed tannin contents were 2.58 mg/g, 29.84 mg/g, and 15.94 mg/g, respectively. Compared to experimental day 0, there was an increase in EPG of 80.83% in the control group, a decrease of 24.72% in group 2, and a 20% decrease in group 3, by day 28. The -value was <0.05 between group 1 and the other groups, showing significant differences between the control and experimental groups. The decrease in EPG rates in the experimental groups compared to the control group demonstrates an antiparasitic effect of and chicory.
养羊户控制胃肠道蠕虫的一般做法是使用商业药物，这使得化学抗性非常普遍。考虑到这一点，我们的研究重点是使用高单宁植物干草对胃肠道寄生虫进行生物防治。每组30只动物，共分为三组。对照组额外喂食草地干草，而其他两组分别喂食菊苣（第2组）和鸟足三叶草干草（第3组）。对所有动物的粪便中排出的胃肠道圆线虫卵数量（每克粪便虫卵数，EPG）进行了28天的监测。草地、菊苣和干草补充剂中的总单宁含量分别为13.92毫克/克、78.59毫克/克和94.43毫克/克，其缩合单宁含量分别为2.58毫克/克、29.84毫克/克和15.94毫克/克。到第28天，与实验第0天相比，对照组的EPG增加了80.83%，第2组减少了24.72%，第3组减少了20%。第1组与其他组之间的P值<0.05，表明对照组和实验组之间存在显著差异。与对照组相比，实验组EPG率的降低证明了 和菊苣具有抗寄生虫作用。
