摘  要：
An experiment was conducted to determine the concentration variation of epidermal growth factors (EGF) include insulin-like growth factor - I (IGF- I), transforming growth factor-facta(TGF-β), and basic fibroblast growth factor (bFGF)in colostrum andnormal milk of sows within 35 days after parturition The results showed that the concentration of EGF, IGF- I, TGF-β, bFGF was significantly higher in colostrum than that in normal milk. The concentration of these growth factors in colostrum was significantly decreased with the stage lapse of lactation, and then they remained stable in normal milk. Parity had a slight effect on the concentration of these growth factors.
