Six experiments were carried out in Western Australia to further investigate the effect of zinc supplementation on the reproductive performance of grazing Merino ewes. There was a small increase (7%,P=0.1) in the number of lambs produced by zinc-supplemented ewes in only one of the six experiments. Plasma zinc levels just prior to lambing were increased by zinc supplementation in two experiments. These results are discussed and compared to the previously published reproductive responses to zinc supplementation by grazing Merino ewes.
六项实验在西澳大利亚进行,旨在进一步研究补锌对放牧美利奴母羊繁殖性能的影响。仅在其中一项实验中,补锌母羊产羔数略有增加(7%,P=0.1)。在两项实验中,锌补充剂增加了分娩前的血浆锌水平。本文对这些结果进行了讨论,并与先前发表的放牧美利奴母羊对锌补充的繁殖反应进行了比较。
