摘要

本试验旨在研究饲粮中添加苜蓿草粉或发酵苜蓿草粉对鹅生长性能、血清抗氧化酶及消化酶活性的影响。选用162只狮头鹅,随机分为9组,每组3个重复,每重复6只鹅。对照组饲喂基础饲粮,试验组饲喂分别添加5%、10%、15%和20%的苜蓿草粉或发酵苜蓿草粉的试验饲粮。试验期35 d。结果表明:1)饲粮添加苜蓿草粉或发酵苜蓿草粉对鹅的平均日增重产生显著二次和交互影响(P<0.05),对平均日采食量的线性和交互无显著影响(P>0.05),对料重比无显著影响(P>0.05)。饲粮添加10%发酵苜蓿草粉组,鹅的平均日增重最高,较对照组提高了19.48%(P<0.05)。2)饲粮中添加苜蓿草粉对鹅血清谷胱甘肽过氧化物酶(GSH-Px)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)活性和丙二醛(MDA)含量有显著交互影响(P<0.05),5%、10%苜蓿草粉组及5%发酵苜蓿草粉组血清GSH-Px、SOD和CAT活性与对照组差异不显著(P>0.05),其他各组与对照组差异显著(P<0.05)。3)饲粮中添加苜蓿草粉对胃蛋白酶、胰脂肪酶、十二指肠蛋白酶和脂肪酶活性无显著影响(P>0.05)。饲粮中添加苜蓿草粉或发酵苜蓿草粉对胰蛋白酶、胰淀粉酶活性产生显著二次和交互影响(P<0.05)。10%苜蓿草粉组胃蛋白酶、胰淀粉酶、十二指肠淀粉酶活性显著高于对照组(P<0.05),但与5%苜蓿草粉组无显著差异(P>0.05)。由此可见,在鹅饲粮中添加一定量的苜蓿草粉或发酵苜蓿草粉可以促进其生长,提高血清抗氧化酶和消化酶活性,添加发酵苜蓿草粉效果更好。

Abstract

This experiment was conducted to study the effects of dietary alfalfa meals (AM) or fermented alfalfa meals (FAM) on growth performance, serum antioxidant enzyme and digestive enzyme activities of geese. A total of 162 Shitou geese were randomly assigned to 9 groups with 3 replicates per group and 6 geese per replicate. Geese in the control group were fed a basal diet, and the others were fed the experimental diets supplemented with 5%, 10%, 15% and 20% AM or FAM, respectively. The results showed as follows: 1) dietary AM or FAM had significant quadratic and interaction effects on average daily gain (ADG) of geese (P<0.05), but had no significant linear and interaction effects on average daily feed intake (P>0.05), also had no significant effect on feed/gain (P>0.05). Compared with the control group, the 10% FAM group had the best ADG, and increased by 16.49% (P<0.05). 2) Dietary AM had significant interaction effect on serum glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT) activities and malonaldehyde (MDA) content (P<0.05). The serum GSH-Px, SOD and CAT activities in 5%, 10% AM and 10% FAM groups had no significant difference compared with those in control group (P>0.05), but the other groups had significant difference compared with those in control group (P<0.05). 3) Dietary AM had no significant effect on the activities of trypsin in stomach, lipase in pancreas and trypsin and lipase in duodenum (P<0.05). Dietary AM or FAM had significant quadratic and interaction effect on the activity of trypsin and amylase in pancreas. The activities of trypsin in stomach, amylase in pancreas and amylase in duodenum in 10% AM group were significantly higher than those in control group (P<0.05), but had no significant difference compared with those in 5% AM group (P>0.05). In conclusion, dietary supplemented with AM or FAM can promote the growth of geese, and improve the serum antioxidant enzyme and digestive enzyme activities. Dietary supplemented FAM has the better effect.
