Mixed grazing of breeding goats and cattle (goats to cattle ratio: about 50 %, based on metabolic weight) was monitored for 2 years on a rotational pasture with the two species grazing together, then for 5 years with cattle grazing immediately after goats. For both modalities, the level of goat parasite infection was not significantly different from that of the control groups. Nevertheless, the association allowed a slight improvement in kid growth and goat productivity, probably in relation to a better food quality. The response of adult goats to mixed grazing is therefore very different from that previously obtained with kids post-weaning. The question of the relationship between heterogeneity of pastures, knowledge of their environment, grazing behaviour of adult goats and risk of infection with gastrointestinal nematodes requires further investigation.

成年山羊和牛的混合放牧：长期监测的教训。

在旋转牧场上对两种山羊一起放牧，监测了繁殖山羊和牛的混合放牧（山羊与牛的比率：约50％，基于代谢重量）约2年，然后在山羊之后立即放牧了5年。对于这两种方式，山羊寄生虫感染的水平与对照组均无显着差异。尽管如此，该协会还是使孩子的成长和山羊的生产力略有改善，这可能与更好的食品质量有关。因此，成年山羊对混合放牧的反应与断奶后孩子先前获得的反应非常不同。牧场异质性，环境知识，
