豆科牧草尤其是三叶草属和紫花苜蓿含有丰富的植物雌激素。植物雌激素因化学结构与动物雌激素相似而发挥雌激素和抗雌激素的生物学功能。在畜牧生产中,适量的植物雌激素具有促进家畜生长以及提高机体免疫能力等作用,但家畜采食过多,则会引起家畜特别是反刍家畜繁殖功能的紊乱。然而,豆科牧草的植物雌激素含量在植物生育期变化幅度大,且受到许多因素影响,如植物、生态和栽培管理等,这些因素可能提高或降低豆科牧草的植物雌激素含量,因此了解这些因素对豆科牧草植物雌激素含量的影响,可以在畜牧生产中利用植物雌激素有利的作用和避免不利的作用。
Legumes, especially clover and alfalfa, are rich in phytoestrogens. Phytoestrogens exert the biological functions of estrogen and anti-estrogen due to their chemical structure similar to that of animal estrogens. In animal husbandry, the appropriate amount of phytoestrogens can promote the growth of livestock and enhance the immune function of the body. However, over-eating of livestock can cause the disturbance of reproductive function of livestock, especially ruminants. However, the phytoestrogen content of leguminous forages varies greatly during plant growth and is influenced by many factors, such as plant, ecology and crop management, which may increase or decrease the phytoestrogen content of leguminous pasture and therefore understand The effect of these factors on estrogen levels in leguminous pasture plants can take advantage of the beneficial effects of phytoestrogens in livestock production and avoid adverse effects.
