摘  要：
在猪饲料中最广泛使用的动物蛋白是肉骨粉和鱼粉,它们都含有相对含量较高的氨基酸,也是可消化钙、磷的良好来源。在鱼粉和肉骨粉中,磷的消化率和产品中灰分含量是呈负相关的。家禽产业的副产物包括鸡肉粉、家禽副产物和AV-E Digest都广泛用于饲喂断奶仔猪,因为这些产品有助于提高断奶仔猪的生长性能。水解羽毛粉是另一个家禽产业的副产物,可以用于生长育肥猪的饲料。水解小肠蛋白在近年来也已经允许用于断奶仔猪饲料的氨基酸来源。血液制品,无论是通过环形干燥、滚筒干燥或喷雾干燥的,都是有价值的氨基酸和磷的来源,喷雾干燥的血液制品具有非常好的氨基酸消化率。乳制品工业的副产品包括乳清粉和低蛋白乳清粉,不像其他动物源性饲料原料一样,乳清粉和低蛋白乳清粉氨基酸含量不丰富,主要是作为乳糖的来源饲喂断奶仔猪,并且乳清粉和低蛋白乳清粉的磷都具有很高的消化率。

摘  要：
The most commonly used animal proteins in the swine feed industry are meat and bone mealand fish meal, which have a relatively high concentration of amino acids(AA) and also excellent sourcesof digestible Ca and P. The concentration of bones in these products is reflected in the concentration ofash and the digestible of P in fish meal and meat and bone meal is negatively correlated with the con-centration of ash in the products. By-products of the poultry industry include chicken meal, poultry byproduct meal, and AV-E digest, which are often included in diets fed to weanling pigs, because these in-gredients contribute to an increase in performance of newly weaned pigs. Hydrolyzed feather meal is al-so a by-product of the poultry industry that may be used in diets fed to growing finishing pigs. Hydro-lyzed intestinal proteins have become available during recent years and are now often included as AAsources in dies fed to weanling pigs. Blood products, either ring dried, drum dried, or spray dried, are al-so valuable sources of AA, and the spray dried blood products have excellent digestibility values for AAand P. Co-products of the dairy industry includes dried whey powder and whey permeate. Unlike otherfeed ingredients of animal origin, whey powder and whey permeate are not rich in AA and they are pri-marily used in diets fed to weanling pigs as sources of lactose. However, whey powder and whey perme-ate also provide an excellent digestibility.
