Abstract:

In order to study the effects of Ampelopsis grossedentata extract on growth performance,blood biochemical indexes and antioxidant activities in pigs at different weight stages,ninety crossbred (Duroc×Landrace×Yorkshire) castrated boars with an average initial body weight of 30 kg were randomly divided into three groups,CON group (fed with basal diet),group A (fed with basal diet adding 0.03% plant essential oil complex)and group B (fed with basal diet adding 0.03% Ampelopsis grossedentata extract),respectively.Pigs were fed with different basic diets according to body weight stages (30-50,50-75,75-100 kg and 100 kg-out).Pigs were weighted and blood samples were collected before and after each change of basic diets to analysis the effects of 0.03% Ampelopsis grossedentata extract on the growth performance,blood biochemical parameters and antioxidant activity of different weight stages pigs.The results showed that:Compared with the CON group,adding 0.03% Ampelopsis grossedentata extract significantly increased ADFI and ADG of the 30-75 kg pigs (P<0.05).The content of blood lactic acid (LA) was significantly decreased at 30-50 kg body weight (P<0.05).At 50-75 kg,the insulin (INS) concentration in blood was significantly increased (P<0.05),but there was no significant difference in blood glucose (GLU) concentration (P>0.05).At 75-100 kg,GLU concentration was significantly elevated (P<0.05),meanwhile there was an increased trend for INS concentration (P>0.05),and the content of lactate dehydrogenase (LDH) was significantly decreased (P<0.05).There was an increased trend for serum growth hormone (GH) content at each weight stage (P>0.05).Serum T-SOD activity,MDA content,GSH-Px activity,and TAOC were not significantly different compared with the CON group at any weight stage (P>0.05).Compared with the plant essential oil complex group,addition 0.03% Ampelopsis grossedentata extract significantly increased the ADFI of the pigs at 30-100 kg body weight stage (P<0.05),and significantly reduced the content of LA of 30-50 kg pigs (P<0.05),and significantly increased the GSH-Px activity at the weight of 50 kg or more (P<0.05).In conclusion,adding 0.03% Ampelopsis grossedentata extract could promote the growth and metabolism of pigs at 30-75 kg,and improve the carbohydrate metabolism of pigs at 50-100 kg body weight to some extent,and the effect of adding Ampelopsis grossedentata extract was superior to the plant essential oil complex at the same amount.
