摘要
An experiment was conducted to study the effects of dietary Semen Vaccariae (SV) on mammary development and lactation potential in rats. Forty-eight Sprague-Dawley female rats after parturition were selected and assigned to two groups randomly, with 24 rats each. Control rats were offered basal diets from the beginning to the end of the lactation period. A total of 1% SV was added to the basal diet to form an experimental diet. After parturition, the litter size was culled to eight pups per dam. Estimated milk yield was improved 29.82% (P<0.05) by feeding SV on day 18 of lactation. Serum growth hormone, insulin-like growth factor-1 and prolactin concentrations in dams were significantly higher (P<0.05) in the SV group than in the control group on day 18 of lactation. Dietary SV increased wet weight and DNA contents of dam mammary (P<0.05). The results suggest that dietary SV stimulates mammary development and promotes lactation in rats.
