Effects of Dietary Ginger Root, Star Anise and Dan-shen Root on Antioxidant Status and Reproductive Performance of Sows during Late Gestation and Lactation
The experiment was conducted to study the effects of diatary ginger root, star anise and dan-shen root on antioxidant status and reproductive performance of sows during late gestation and lactation.A total of 36 Laiwu Black pregnant sows with average weight of 164.28 kg ± 1.30 kg and similar parity were randomly divided into 4 treatments with 9 replicates per treatment.The control group was fed a basal diet,and the experimental groups were fed the basal diet supplemented with 10 g/kg ginger root,5 g/kg star anise and 10 g/kg dan-shen root,respectively (ie Cont., GIN, SA, DS groups).The results showed that the concentrations of glutathione in serum and milk protein in colostrum, activity of total antioxidant capacity in colostrum of GIN, SA and DS groups were significantly higher than that of Cont.group (P＜0.05).The concentration of milk fat in colostrum of GIN and DS groups were higher than that of Cont.group (P＜0.05).Comparing to Cont.group,the concentration of lactose in colostrum was significantly higher (P＜0.05) of SA and DS groups.All groups had similar number of born live,21 d survival rate,birth weight of born and 21 d weight of born (P＞0.05).In conclusion, dietary supplementation of 10 g/kg ginger root,5 g/kg star anise and 10 g/kg dan-shen root could increase antioxidant status of serum and colostrum of sows,improve the nutritional value of colostrum,but had no effect on reproductive performance.
