静脉血内脂素和胰岛素样生长因子Ⅰ与犊牛初生重相关性研究
Relationship of Visfatin and IGF-Ⅰ in Venous Blood with Calf Birth Weight
摘要
Abstract
[Purpose] In order to explore the correlation between visfatin,IGF-Ⅰ in cow calf and cord venous blood and calf birth weight (CBW).[Method] 54 healthy Chinese Holstein cows,which experienced normal delivery,were used in the present study.The cows were grouped according to birth weight of their calves (group A:≤40 kg,n =9;group B:40-45 kg,n =25;group C:≥45 kg,n =20).Cow,calf and cord venous blood were collected respectively after delivery.ELISA was used to evaluate the level of visfatin and IGF-Ⅰ in serum,the correlation among them as well as correlation with CBW was analyzed.[Result] Visfatin and IGF-Ⅰ expressed in cow,calf and cord venous blood.With the increase in CBW,the visfatin in calf and cord venous blood of group A were significant higher those of group C (P ＜ 0.05),the IGF-Ⅰ in calf and cord venous blood of group A and group B were significant higher than those in group C (P ＜ 0.05),and the differences of other indexes were not significant in groups (P ＞ 0.05).The visfatin and IGF-Ⅰ in cow,calf and cord venous blood had highly significant positive correlation with each other (P ＜ 0.01).CBW had no significant correlation between the expression levels of visfatin and IGF-Ⅰ in cow venous blood (P ＞ 0.05),but had significant correlation between visfatin in calf venous blood (P ＜ 0.05) and had highly significant correlation with IGF-Ⅰ in calf and cord venous blood and visfatin in cord venous blood (P ＜ 0.01).There were no significant correlation between the expression levels of visfatin and IGF-Ⅰ in cow venous blood and those in calf and cord venous blood (P ＞ 0.05);while visfatin and IGF-Ⅰ in calf venous blood had highly significant positive correlation with those in cord blood venous (P ＜ 0.01).Visfatin and IGF-Ⅰ in cow,calf and cord in venous blood had no significant differences between the male and the female calf respectively (P ＞ 0.05).[Conclusion] There were visfatin and IGF-Ⅰ expressed in cow,calf and cord venous blood,visfatin and IGF-Ⅰ in calf and cord venous blood can affect CBW rather than those in cow venous blood;Visfatin and IGF-Ⅰ in cow,calf and cords venous blood had no significant differences between the male and the female calf respectively.关键词
