摘  要：
采用微卫星技术及最小二乘拟合线性模型,利用崂山奶山羊、济宁青山羊、鲁北白山羊和莱芜黑山羊4个地方山羊品种中的10个多态性微卫星基因座,分析了微卫星基因座及其等位基因对山羊生长性状的关联效应。结果表明:与品种、性别和年龄等因子比较,标记因子对山羊体重和体尺性状的影响较小,但发现BM6404、BM1818、BM812和BM6444基因座对体重有显著影响(P<0.05或P<0.01),BM6404、BM1818、BMS12484、MAF70基因座对主要体尺性状有显著影响(P<0.05或P<0.01)。BM6404基因座的等位基因130可能对山羊的胸围、体高、尻宽均有正效应;120对胸围有较强的负效应,而对体高、尻长则有较强的正效应;168对尻长、尻宽均表现为负效应。MAF70基因座的等位基因142对体长有正效应,178对体长有负效应。BMS1248基因座的等位基因128对管围有正效应。

摘  要：
Ten polymorphic microsatellite loci among 4 local goat breeds(Laoshan dairy goat,Jining grey goat,Lubei white goat and Laiwu black goat) in China were used to analyse the relating effect between their alleles and growth traits,by using general linear model(GLM) and microsatellite analysis technique.The results showed that,compared with the breed,sex and age factors,microsatellite marker factor had less effect on body weight and body size traits,however,BM6404,BM1818,BM812 and BM6444 affected body weight significantly(P<0.05 or P<0.01),and BM6404,BM1818,BMS12484,MAF70 had significant effect on main body size traits(P<0.05 or P<0.01).We also found that,allele 130 of BM6404 had positive effect on heart girth,height at withers and thurl width,allele 120 had negative effect on heart girth,and positive effect on height at withers and rump length;allele 168 had negative effect on rump length and thurl width.For MAF70,allele 142 had positive effect and allele 178 had negative effect on body length respectively.For BMS1248,allele 128 had positive effect on circumference of cannon bone.
