| 摘要: |
| 采用比色法和放射性免疫法测定了西农莎能奶山羊乳中RNA,S-HT,CAMP,CGMP和血清中LDH,AKP的含量为:0.432,0.408,0.405,0.473,0.194,0.405。其产奶量(300天)、产脂量、乳蛋白量、乳脂率、乳蛋白率的遗传力分别为0.297,0.323,0.313,0.387,0.401;遗传相关和表型相关分析表明生化性状与泌乳性能关系密切;通径分析表明RNA,S-HT,CAMP,CGMP之间对泌乳是正向协同作用。 |

| Abstract: |
| The contents of Riboncules acid(RNA), 5-hydroxyptamine (5-HT), Cyclic adenosine monophosphate (CAMP) , Cyclic guanosine monophosphate (CGMP) in milk; and the activites of Alkine phosphatese (AKP) , lactic dehydrogemase (LDH) in serum were determined by Chromometry and radioimmunoassay. The genetic parameters of determined traits were estimated. The heritabilities of RNA, 5-HT, CAMP, CGMP, AKP, LDH, milk yields (300 days) , fat yields, protein yields, fat percentage and protein percentage are 0.434/0.408/0.405/0.473/0.391/0.194/0.297/0.323/ 0.313/0.337/0.401/ respectively. The analysis of genetic and phenotypic correlation indicates that biochemical traits are closely related to milk production characters, path analysis also shows that RNA, 5-HT, CAMP CGMP have the positive effects of coordination with each other in milk production charaters or traits. |
