猪血清β-及前β-脂蛋白含量与瘦肉率的相关研究

STUDIES ON THE CORRELATIVITY BETWEEN SERUM β-PLUS PRE β-LIPOPROTEIN CONTENT AND LEAN PERCENTAGE IN THE PIGS

本试验采用生化技术,对北京花猪(6头)和长花猪(长花猪×北京花猪;11头)血清中的β-及前β-脂蛋白等生化标记的含量进行了检验和相应的胴体部分品质分析。实验结果表明,血清中β-及前β-脂蛋白含量与瘦肉率呈显著负相关(北京花猪 r=-0.97,长花猪 r=-0.44),与脂肪率呈显著正相关(北京花猪 r=0.93,长花猪 r=0.55)。初探结果表明,血清中β-及前β-脂蛋白含量有可能作为瘦肉型猪的选种指标之一。

An experiment was exploited biochemical technologies to test serum β-plus pre β-Lipoprotein content of biochemical indicators in Beijing Spotted line Ⅰ (n=6)and Landrace×Bejiing Spotted(n=11)and carcass quality are analyzed. Results indicated that a remarkable negative correlationexists between β-plus pre β-Lipoprotein contens in the serum and carcass lean percentage(Beijing Spotted lineⅠ,r=-0.9677,landrace×Beijing Spotted line I,r=-0.4289)But β-plus pre β-Lipopr cotein content with fat percentage shows remarkable positive corrlation(Beijing Spotted line Ⅰ,r=0.9320,Landraee×Beijing Spotted lineⅠ,r=0.5534)。 preliminary results have elucidated that the content of β-plus pre β-Lipoprotein may become selecting indicators of the lean-type pigs。
