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.
