A poor hay, with a low proteic level, decreases the zinc availability in lambs. Increasing the sulfur level with methionine and sulfate, of such a diet, enhances zinc absorption. However, sulfur is not the only factor limiting zinc availability in a hypoproteic diet.
劣质干草蛋白质含量低，会降低羔羊体内锌的可利用性。在此类日粮中添加蛋氨酸和硫酸盐来提高硫含量，可增强锌的吸收。然而，硫并非低蛋白日粮中限制锌可利用性的唯一因素。
