摘要
本研究选用草原红牛、利木赞与草原红牛杂交后代共计40头作为试验牛群体,以体重、体尺作为衡量牛生长发育的指标,以肉牛线性体型评分方法中的肌肉度线性评分性状和屠宰肉用性状作为衡量牛肉用性能的指标,运用SPSS软件之GLM分析了40头牛21个性状与8个微卫星标记的关系。结果表明,IDVGA55等位基因C穴203bp雪对体高、十字部高和坐骨端高3个体尺性状有正效应;BM2113等位基因C穴142bp雪对腿围、净肉重和净肉率等性状有正面影响;ETH225等位基因A穴123bp雪对腰角宽具有正面影响;ID鄄VGA46等位基因C穴211bp雪对5个肌肉度评分性状耆甲、肩部、腰厚、大腿肌、臀部外形以及胴体重、屠宰率、净肉重和净肉率等屠宰肉用性状有负面影响;BM1824等位基因A穴171bp雪对十字部高、腰厚2个性状有正效应,等位基因C穴179bp雪对胸深性状有正效应;TGLA44等位基因E穴221bp雪对耆甲、腰厚、臀部外形等肌肉度评分性状和体重、胴体重以及净肉重等屠宰肉用性状有正面影响。
In this study, 40 individuals of grassland red cattle(GLRC) and its improved hybrid by Limousine(LM) were chosen as test population. The muscularity evaluation traits in the regulation of linear valuation and slaughtering meaty traits were used to evaluate their beef performance traits, and the body measurement traits and body weight were used to evaluate their growth and development. The relation of 21 traits in a population of 40 cattle and 8 microsatellite markers was analyzed using SPSS. The results showed that, for microsatellite loci IDVGA55, allele C(203 bp) had a positive correlation with body height, height at hip cross(HHC) and height at capitulum body measurement traits. For BM2113, allele C(142 bp) had a positive correlation with gam girth, net meat weight and net meat rate. For ETH225, allele A(123 bp) had a positive correlation with waist corner width. For IDVGA46, allele C(211 bp) had a negative correlation with the five muscularity evaluation and four slaughter meaty traits. For BM1824, allele A(171 bp) had a positive correlation with height at hip cross(HHC) and loin thickness, and allele C(179 bp) had a positive correlation with chest depth. For TGLA44, allele E(221 bp) had a positive correlation with withers, loin thickness, buttocks shape, body weight, carcass weight and net meat weight.
