Abstract:

In order to explore the correlation between adiponectin,leptin,visfatin in placenta and calf birth weight.56 naturally born healthy Chinese Holstein cows were used,in which,cows given birth to calf that were less than 40 kg were included in group A;between 40-45 kg were included in group B;more than 45 kg were included in group C.The placentas were surgically collected immediately after birth.RT-PCR and ELISA were used for evaluation of adiponectin,leptin,and visfatin in placenta,the correlation between adiponectin,leptin,visfatin in placenta and calf birth weight were analyzed.The results showed that,as the calf birth weight increased,the adiponectin and visfatin mRNA and protein expression levels increased,while leptin reduced first and then increased.The expression level of leptin mRNA of group C was significantly higher than that of group B (P<0.05). The difference among group A,B and C were not significant(P>0.05). Adiponectin and visfatin of group A,B and C were not significantly different (P>0.05). The expression level of adiponectin protein in group A and group B had no significant difference (P>0.05).The expression level of adiponectin in group C was significantly higher than that of group A and group B (P<0.05),the expression levels of leptin and visfatin in group A,B and C had no significant differences(P>0.05). The mRNA and protein level of adiponectin and leptin in placenta were positively correlated with calf birth weight(P<0.01).The mRNA and protein level of visfatin in placenta with calf birth weight had no significant correlation(P>0.05).The mRNA and protein expression level of adiponectin,leptin and visfatin in 3 groups had no significant correlation respectively(P>0.05).The results demonstrated that adiponectin,leptin and visfatin were expressed in placenta of cows,which played a role in promoting of calf intrauterine growth cooperatively,adiponectin and leptin had great influence on calf birth weight,visfatin had little influence on calf birth weight.The study provided reference for studying mechanism between adiponectin,leptin,visfatin in placenta of cow and calf birth weight in the future.
