| 摘要: |
| 应用现代生化分析技术分别测定了西农莎能奶山羊乳样中的核糖核酸(RNA)、5-羟色胺(5-HT)、环腺苷酸(cAMP)和环鸟苷酸(cGMP),以及血样的血清乳酸脱氢酶(LDH)和碱性磷酸酶(AKP)等六项指标。借助M340型计算机构造了生化性状和泌乳性状的主成分,所构造的六个主成分包括泌乳性能、生化性状89.5％的信息。用反映泌乳性能的主成分对试验羊进行排序分类,结果与实际情况相符合,经判别分析和检验分类是合理的,证明主分量分析可以作为奶山羊质量评定的一种方法。 |

| Abstract: |
| The contents of Riboncules acid(RNA) 5-hydroxytrytamine(5-HT),cyclic adenosine monophosphate(cAMP), cyclic guanosine monophosphate (cGMP) in milk anb the activities of Alrine phosphese (AKP),lactic dehydrogemase(LDH) in serum in xinong Sannen goats were determined by the modern biochemical techniques respectively. The principal components of biochemcial traits and lecta tion performances were formed with the help of M340-type computer. The six formed components include 89.5% of information of lactation performances and biochemical traits. The principal components reflecting lactation performances were used to carry out sequencing and classification of experimental milk goats whose results are in agreement with the actual conditions. This classification is reasonable through discriminant analysis. It proves that the principal components can be used as an approach to assess the qualities of milk goats. |
