摘要
对辽宁关山种畜场5群150只东北细毛羊育成羊血液中13项生化指标的遗传标志与生产性能的相关性进行研究,结果表明,运铁蛋白遗传多态型是受TfA、TfB和TfC控制,基因频率分别为49.2366％、36.2595％和14.5038％。基因型AA的育成羊体重极显著地高于AB型,AB型育成羊毛量极显著地高于AA型。β-脂蛋白与碱性磷酸酶遗传力高,分别为0.7191、0.5102。β-脂蛋白和产毛量、体重间遗传相关分别为0.96、-0.5622;碱性磷酸酶与产毛量、体重间遗传相关分别为0.7677、-0.4353。本研究证明,运铁蛋白、β-脂蛋白和碱性磷酸酶可以作为选种的遗传标记。
Blood samples were collected from 150 hoggets of the Northeas Fine-wool sheep in 5 flocks in Guan Shan Stock Farm and used to study theinheritance of Transferrin(Tf),Lactic Dehydrogenase(LDH), Alkalin Phosphatase(ALP), Glutamate Pyruvate Transamidase(GPT), Total Protein(TP), Albumin(ALB), β-Lipoprotein (β-LIP),Urea Nitrogen (UN), Total Cholest erol (CHO), Triglyceride(TG), Glucose(GLU), Inorganic Phosphorus(Pi),Calcium(CA), their relationship with 2 major economic traits, wool weight and body and weight.The hoggets with AA Tf types weighed 4.5492Kg more than that of AB in body weight(p<0.01); and 1.467kg less in wool weight(p<0.01). The gene frequencies for TfA, TfB and TfC were 49.2366%, 36.2595% and 14.5038% respectively,and genotype frequencies for AA, AB, AC, BB, BC, and CC were 24.4275%,35.8779%, 13.7405%, 12.2137%, 12.2137% and 1.5267%, respectively .Heritabilities for β-LIP and ALP were 0.7191 and 0.5102,and much higher than those of LDH (0.1148), GPT(0.1034), TP(0.0986), ALB (0.4031),UN(0.2759),CHO(0.0994,TG(0.0345), GLU(0.3609), Pi (0.1279)and CA(0.1136).The genetic correlation of β-LIP with 2 economic traits mentio- ned above were 0.96 and-0.5622;and those of ALP were 0.7677 and-0.4353. It was advisable basically that the Tf,β-LIP,ALP could be consider- ed as genetic markers in animal breeding.
