摘 要:通过对河南省不同类型54个县(市)的饲料样品进行化验分析,并将7种元素的吸收率换算成有效含量。经用典型日粮配方计算,再与猪、鸡营养需要量比较,对我省猪、鸡饲料中微量元素的盈缺作出了判定。结果表明:蛋鸡饲料中钴超过42.04%,而铜、铁、锰、锌、碘、硒分别缺49.57%,55.62%,82.88%,91.12%,71.26%,70.15%;生长猪饲料中铜、铁、锌、碘、硒依次缺31.26%,58.21%,96.38%,32.34%,88.27%,而锰和钴则分别超过168.52%和43.76%。并具有区域性等特点。The contents and digestibilities of 7 trace elements in Henan feedstuffs were measured.The contents of trace elements in typical diets were changed into available contents.Through checking the available contents of trace elements in typical diets with the nutrient requirement of swine and chicken,whether the elements are surplus or deficient is discriminated.In the layer diets,cobalt exceed by 42.04%,whilst Copper,Iron,Manganese,Zinc,Iodine and Selenium are short of 49.57%,55.62%,82.88%,91.12%,71.26%,70.15%,respectively.In the diets of growing pigs,Copper,Iron,Zinc,Iodine and Selenium lack 31.26 %,58.21%,96.38%,32.34%,88.27%,respectively.Manganese and Cobalt surpass by 168.52% and 43.76% respectively.
