饲粮添加抗生素和植物精油对母猪生产性能、免疫功能和乳成分的影响
Effects of Dietary Antibiotics and Plant Essential Oils on Performance, Immunity and Milk Composition of Sows
摘要
Abstract
The objective of present study was to investigate the effects of dietary tylvalosin tartrate (TT) and plant essential oils (PEO) on the performance,immunity and milk composition of sows during last period of pregnancy.A total of 24 Landrace×Yorkshire sows with the same body condition and 3 to 4 fetal times were used in arandom design,which consisted of 3 groups.Pigs in three groups were fed different diets:1) control group,basal diet;2) TT group,basal diet supplemented with 100 mg/kg TT;3) PEO group,basal diet supplemented with 200 mg/kg PEO.Each group had 8 replicates of 1 sow each.The experiment lasted from gestation for 96 days to weaning.The results showed that,dietary supplementation with TT and PEO could improve the production performance of breeding sows.In PEO group,the stillbirth rate was decreased by 71.43％ and 53.33％ (P＞0.05),and the survival rate was increased by 1.17％ and 1.60％ compared with control group and TT group (P＞0.05),respectively.Meanwhile,the mummy rate in PEO group was decreased by 50.00％ compared with the control group (P＞0.05).In addition,the serum immunoglobulin (Ig) A contents of sows in PEO group at the 1st,14th and 21st day after parturition and in TT group at the 21st day after parturition were significantly higher than that in control group (P＜0.05);the contents of whey IgG and IgM of sows in PEO group at the 14th day after parturition were significantly higher than those in the other two groups (P＜0.05),while the whey IgG content of sows in PEO group at the 21st day after parturition was also significantly higher than that in control group (P＜0.05).In conclusion,dietary TT and PEO can improve the performance and immune function of sows,but in contrast,the PEO is better.Thus,PEO has a potential to substitute TT in breeding sows' diets.关键词
