摘要:

为研究日粮中添加藤茶提取物对不同体重阶段猪生长性能、血液生化指标、抗氧化活性的影响,本研究选用平均初始体重为30 kg的三元杂交(杜×长×大)去势公猪90头,随机分成3个处理,分别为对照组(CON组,饲喂基础日粮)、植物精油复合物组(A组,基础日粮中添加0.03%植物精油复合物)和藤茶提取物组(B组,基础日粮中添加0.03%藤茶提取物),根据不同体重阶段(30~50、50~75、75~100 kg及100 kg~出栏)饲喂不同阶段的基础日粮,每次换料前及试验结束时称重采血,分析不同体重阶段添加0.03%藤茶提取物对猪生长性能、血液生化指标、抗氧化活性的影响。结果表明:与CON组相比,添加0.03%藤茶提取物显著提高了30~75 kg猪的平均日采食量(ADFI)和平均日增重(ADG)(P<0.05);显著降低了30~50 kg猪血清乳酸(LA)含量(P<0.05);显著提高了50~75 kg猪血液胰岛素(INS)浓度(P<0.05),但对血糖(GLU)浓度无显著影响(P>0.05);显著提高了75~100 kg猪GLU浓度(P<0.05),INS浓度有升高趋势(P>0.05),乳酸脱氢酶(LDH)含量显著降低(P<0.05);各体重阶段血清生长激素(GH)含量均有升高趋势(P>0.05)。B组猪血清总超氧化物岐化酶(T-SOD)活力、丙二醛(MDA)含量、谷胱甘肽过氧化物酶(GSH-Px)活力、总抗氧化能力(TAOC)在各体重阶段与CON组相比均无显著差异(P>0.05)。与A组相比,添加0.03%藤茶提取物显著提高了30~100 kg猪的ADFI (P<0.05),显著降低了30~50 kg猪血清LA含量(P<0.05),且显著提高了50 kg以上体重阶段猪血清GSH-Px活力(P<0.05)。综合试验结果,添加0.03%藤茶提取物可促进30~75 kg猪生长代谢,在一定程度改善50~100 kg猪的血糖代谢,且添加藤茶提取物效果优于添加等量植物精油复合物。

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.
