Chemical composition of meat-and-bone meals (n = 22), poultry by-product meals (n = 12), blood meals (n = 6), bone meals (n = 4) and feather meals (n = 8) indicated a slight degree of overdrying. Crude fat and ash contents were within the acceptable limits. Mineral elements of bones were determinative in the element pattern of meat-and-bone meals as indicated by the significant correlations between Ca, P and Mg. Crude protein was in negative regression and correlation with crude ash content (r = -0.81; P less than 0.001). This was more pronounced when the data were expressed in fatless dry matter (r = -0.94; P less than 0.001). Crude protein also showed significant negative correlations with Ca, P and Mg contents, offering the possibility to predict their levels from nitrogen content. Meat-and-bone meals and poultry by-product meals were relatively rich sources of riboflavin, niacin, pantothenic acid and biotin, whereas their pyridoxine and thiamine contents were low. Blood meals, bone meals and feather meals were found to be negligible vitamin B sources. Vitamin B and crude protein content of abattoir by-product meals showed uncertain correlations.
肉骨粉（n = 22）、禽副产品粉（n = 12）、血粉（n = 6）、骨粉（n = 4）和羽毛粉（n = 8）的化学成分表明存在轻微程度的过度干燥。粗脂肪和灰分含量在可接受范围内。如钙、磷和镁之间的显著相关性所示，骨骼中的矿物质元素在肉骨粉的元素模式中起决定性作用。粗蛋白与粗灰分含量呈负回归和负相关（r = -0.81；P < 0.001）。当数据以无脂干物质表示时，这种情况更为明显（r = -0.94；P < 0.001）。粗蛋白与钙、磷和镁含量也呈显著负相关，这使得从氮含量预测它们的水平成为可能。肉骨粉和禽副产品粉是核黄素、烟酸、泛酸和生物素的相对丰富来源，而它们的吡哆醇和硫胺素含量较低。血粉、骨粉和羽毛粉被发现是可忽略不计的维生素B来源。屠宰场副产品粉的维生素B和粗蛋白含量显示出不确定的相关性。
