In continuation of our studies on the use of pig manure in ruminant feeding, the present paper is concerned with the investigation of the effects of solids from semi-liquid pig manure as ration components on the crude nutrient and amino-acid contents of the longissimus dorsi muscles of bulls, heifers and calves from experimental and control groups each including 6 animals. There was no difference in the crude protein, pure protein and crude ash contents between the control and the experimental groups. On the contrary, the data on dry matter and crude fat in the longissimus dorsi muscle were significantly lower in the experimental animals than in the control animals. This difference is explained by the fact that the energy content of the experimental ration (containing solids from semi-liquid pig manure) is lower than that of the standard ration. The results obtained from the analysis for 17 amino acids show that the change in amino-acid content of the muscle protein is not determined by the use of solids from semi-liquid pig manure.
作为我们关于猪粪用于反刍动物饲养研究的延续，本文关注半液体猪粪固体作为日粮成分对实验组和对照组公牛、小母牛及犊牛背最长肌粗养分和氨基酸含量的影响，每组各有6只动物。对照组和实验组之间的粗蛋白、纯蛋白和粗灰分含量没有差异。相反，实验组动物背最长肌中的干物质和粗脂肪数据显著低于对照组动物。这种差异可解释为实验日粮（含半液体猪粪固体）的能量含量低于标准日粮。对17种氨基酸的分析结果表明，肌肉蛋白氨基酸含量的变化并非由使用半液体猪粪固体所决定。
