摘要：

为了研究性别和品种对猪血液生化指标的影响，以及血糖、血脂与脂肪沉积性状的相关性，本试验对莱芜猪及苏太猪血液生化指标和脂肪沉积性状进行了测定。采用全自动血液生化分析仪，检测了251 头莱芜猪和248 头苏太猪6 项血液生化指标。结果表明，性别间仅莱芜阉公猪的低密度脂蛋白胆固醇极显著高于母猪（P<0.01），其他血液生化指标差异不显著（P>0.05）；品种间莱芜猪血液葡萄糖、糖化血清蛋白、低密度脂蛋白胆固醇极显著高于苏太猪（P<0.01），而高密度脂蛋白胆固醇极显著低于苏太猪（P<0.01），其他两项血液生化指标品种间差异不显著；莱芜猪和苏太猪的血糖以及部分血脂指标与脂肪沉积性状有显著相关性，在莱芜猪中，总胆固醇、低密度脂蛋白胆固醇与胸部（6~7肋）背膘厚呈极显著正相关（P<0.01），低密度脂蛋白胆固醇与臀部背膘厚呈显著正相关（P<0.05）；在苏太猪中，血液葡萄糖、总胆固醇和高密度脂蛋白胆固醇与肩部背膘厚、胸部背膘厚、腰部背膘厚、臀部背膘厚呈显著或极显著正相关（P<0.05或P<0.01），糖化血清蛋白与臀部背膘厚呈显著正相关（P<0.05），甘油三酯含量与肩部背膘厚、腰部背膘厚呈显著正相关（P<0.05）。由此我们推测：性别对血液生化指标有一定影响，而品种间血液生化指标有显著差异，血糖、血脂与脂肪沉积性状存在显著相关性。

Abstract:

To study the effects of gender and breed on blood biochemical parameters and the correlations between blood glucose，blood lipids and fat deposition，we measured the blood physiological and biochemical parameters and fat deposition traits in Laiwu and Sutai pigs.Total 6 blood physiological and biochemical parameters were measured in both 251 Laiwu and 248 Sutai pigs by using automatic biochemical analyzer.The results showed that，compared to the gilts，the castrated male pigs had significantly higher LDL-C level (P<0.01)，but no significant difference was identified in other blood biochemical parameters between genders (P>0.05) in Laiwu pig.We further compared the phenotypic values of blood glucose and lipids between Laiwu and Sutai pigs，and found that GLU，GSP，LDL-C were significantly higher in Laiwu pigs than that in Sutai pigs (P<0.01).However，Laiwu pigs had significantly lower HDL-C than Sutai pigs (P<0.01).The other 2 blood biochemical parameters had no significant differences between Laiwu and Sutai pigs.Blood glucose and some blood lipid traits were significantly associated with fat deposition traits in Laiwu and Sutai pigs.Correlation analysis found that T-CHOL and LDL-C had extremely significant positive correlation with chest (6-7 ribs) backfat thickness (P<0.01)，LDL-C showed significantly positive correlation with hip backfat thickness in Laiwu pigs (P<0.05).In Sutai pigs，GLU，T-CHOL and HDL-C exhibited significantly (P<0.05) or extremely significant (P<0.01) positive correlations with shoulder backfat thickness，chest backfat thickness，waist backfat thickness and hip backfat thickness，GSP had significantly positive correlation with hip backfat thickness (P<0.05)，further，TG showed significantly positive correlation with shoulder backfat thickness and waist backfat thickness (P<0.05).In conclusion，we suggest that gender may have effect on porcine blood glucose and lipid levels，therefore，breed has significant effect on blood physiological and biochemical parameters.Blood glucose and lipids are significantly correlated with fat deposition traits in Laiwu and Sutai pigs.

Key words: Laiwu pigs, Sutai pigs, blood glucose, blood lipids, fat deposition traits
