Effects of Camellia Oil Supplementation in Lactation Diets on Serum Hormone Levels,Antioxidant Indices and Reproductive Performance of Multiparous Sows
摘要
Abstract
This experiment was conducted to investigate the effects of camellia oil on the reproductive perfor-mance of multiparous sows.A total of 40 multiparous Landrace×Yorkshire crossbred sows with 5 to 6 pari-ties during lactation were randomly divided into four groups:the Control group,CO1 group,CO2 group and CO3 group,with 10 sows per group.Sows in each group were supplemented with 0,30,60 and 120 mL/(sow·d)of camellia oil in their diets,respectively,from parturition to weaning(21 d).The results showed that:① There was no significant difference in the weaning-to-estrus interval among the CO1,CO2,CO3 groups and the Control group(P>0.05).The estrus rate of the Control group was 80%,while that of the CO1,CO2 and CO3 groups was 100%.② The follicle-stimulating hormone(FSH)levels in the CO2 and CO3 groups were extremely significantly higher than those in the Control group(P<0.01);the luteinizing hormone(LH)levels in the CO1 and CO2 groups were extremely significantly higher than those in the Control group(P<0.01);the estradiol(E2)level in the CO2 group was extremely significantly higher than that in the Control group(P<0.01);the Anti-Müllerian hor-mone(AMH)levels in the CO1 and CO2 groups were extremely significantly higher than those in the Control group(P<0.01),and the AMH level in the CO3 group was significantly higher than that in the Control group(P<0.05).③ The reactive oxygen species(ROS)levels in the CO2 and CO3 groups were extremely significantly lower than those in the Control group(P<0.01);the malondialdehyde(MDA)level in the CO1 group was extremely significantly lower than that in the Control group(P<0.01),and the MDA level in the CO2 group was significantly lower than that in the Control group(P<0.05);the superoxide dismutase(SOD)activity in the CO1 group was extremely significantly higher than that in the Control group(P<0.01).The catalase(CAT)and glutathione(GSH)levels in the CO1,CO2 and CO3 groups were extremely signifi-cantly lower than those in the Control group(P<0.01).④ The average total litter size and average live litter size at birth in the CO3 group were significantly higher than those in the Control group(P<0.05);the average birth weight of piglets in the CO1 group was extremely significantly higher than that in the Control group(P<0.01).In conclusion,dietary supplementation of camellia oil for multiparous sows during lactation can improve serum hormone levels,antioxidant capacity and reproductive performance of sows.关键词
