【摘要】：试验旨在对半细毛羊常用饲料原料的营养价值进行评定。采集7种云南半细毛羊常用的饲料原料,采用概略养分分析法测定干物质、有机物、粗蛋白质、粗脂肪、粗纤维、中性洗涤纤维、酸性洗涤纤维等常规养分,并通过消化代谢试验测定各饲料原料的可消化粗蛋白、消化能和代谢能含量。在消化代谢试验中,粗饲料采用直接饲喂法,精饲料采用套算法。结果表明:由于所选7种原料在日粮中的使用目的不同,因此常规养分差异较大,其中干物质含量26.21%~91.13%,粗蛋白含量7.16%~44.73%,粗纤维含量3.71%~34.66%;这7种原料的可消化粗蛋白30.99~399.95 g/kg,消化能8.64~17.19 MJ/kg,代谢能7.07~15.81 MJ/kg,均以豆粕为最高值。通过比较分析,本试验测定的云南半细毛羊常用饲料原料的常规营养成分及可消化粗蛋白和有效能值均与中国饲料营养成分表有一定差异,从而为这7种原料在云南半细毛羊上的合理利用及中国饲料数据库的进一步完善提供一定的参考。
[Abstract]:The aim of the experiment was to evaluate the nutritional value of common feed materials of semi-wool sheep. Seven kinds of common feed materials of Yunnan semi-fine wool sheep were collected, and the routine nutrients, such as dry matter, organic matter, crude protein, crude fat, crude fiber, neutral washing fiber and acid washing fiber, were determined by the method of general nutrient analysis. Digestible crude protein, digestible energy and metabolic energy were determined by digestion and metabolism test. In digestion and metabolism test, roughage was fed directly and concentrate was fed with a set of algorithms. The results showed that the seven kinds of raw materials were used for different purposes in the diet, so there was a great difference in conventional nutrients. The dry matter content was 26.21%, the crude protein content was 7.16% and the crude fiber content was 3.71% and 34.66%. The digestible crude protein of these seven kinds of raw materials was 30.9999.95 g / kg, the digestibility energy was 8.64 ~ 17.19 MJ / kg, the metabolic energy was 7.0715.81 MJ / kg, and the highest value was soybean meal. By comparison and analysis, it was found that the nutritional composition, digestible crude protein and effective value of the commonly used feed raw materials of Yunnan semi-wool sheep were different from those of Chinese feed nutrient composition table. The results provided some references for the rational utilization of these seven kinds of raw materials on Yunnan semi-fine wool sheep and the further improvement of feed database in China.
