花椒渣营养价值评定及其对4～8周龄三穗鸭生长性能和血浆生化指标的影响OA
Nutritional Evaluation of Zanthoxylum bungeanum Residue and Its Effects on the Growth Performance and Plasma Biochemical Indices of Sanshui Ducks From 4 to 8 Weeks of Age
[目的]本研究旨在评价花椒渣营养价值,并探究饲粮中添加花椒渣对三穗鸭生长性能及血浆生化指标的影响,估测三穗鸭饲粮中花椒渣的适宜添加量.[方法]试验通过测定花椒渣粗蛋白质、氨基酸等营养成分,并采用强饲法测定鸭的表观代谢能.基于此进一步开展饲养试验,选取320只28日龄健康、体重相近的三穗鸭,随机分成5组,每组8个重复,每个重复8只鸭,分别饲喂添加不同水平(0(对照组)、2%、4%、6%、8%)花椒渣的基础饲粮,试验期28 d.试验结束后统计鸭终末体重(FBW)、平均日增重(ADG)、平均日采食量(ADFI)、料重比(F/G)等生长性能指标,并采集血液样品,测定血浆生化指标.[结果]花椒渣干物质、粗蛋白质、蛋氨酸、赖氨酸、苏氨酸含量分别为90.16%、14.74%、0.10%、0.49%和0.34%,鸭表观代谢能和真代谢能分别为9.49和11.87 MJ/kg.饲养试验结果显示,与对照组相比,饲粮中添加6%、8%花椒渣后三穗鸭FBW、ADG和ADFI显著降低(P<0.05),添加6%花椒渣后三穗鸭F/G显著增加(P<0.05);饲粮中添加2%、4%花椒渣后三穗鸭FBW和ADFI显著降低(P<0.05),但ADG和F/G均无显著变化(P>0.05).与对照组相比,饲粮中添加2%、4%、6%和8%花椒渣后三穗鸭血浆中天门冬氨酸氨基转移酶(AST)活性显著降低(P<0.05),血浆中尿酸(UA)含量显著升高(P<0.05).[结论]花椒渣可作为非常规饲料资源在鸭饲粮中有限使用.本试验条件下,4～8周龄三穗鸭饲粮中推荐添加量不超过2%.
[Objective]This study aimed to evaluate the nutritional value of Zanthoxylum bungeanum residue and investigate the effects of substituting soybean meal with Zanthoxylum bungeanum residue in the diet on the growth performance and plasma biochemical indices of Sansui ducks,in order to estimate the appropriate supplemental level of Zanthoxylum bungeanum residue in the diet.[Method]This study determined the crude protein and amino acid contents of Zanthoxylum bungeanum residue and evaluated its metabolizable energy in ducks using the forced-feeding method.Based on this,further feeding experiment was carried out.A total of 320 28-day-old healthy Sansui ducks with similar body weight were randomly assigned to 5 groups with 8 replicates of 8 ducks each.The ducks were respectively fed with basal diets supplemented with different levels(0(control group),2%,4%,6%,and 8%)of Zanthoxylum bungeanum residue.The experimental period was 28 days.After the experiment,the final body weight(FBW),average daily gain(ADG),and average daily feed intake(ADFI)of the ducks,as well as the feed-to-gain ratio(F/G),were statistically analyzed.Blood samples were also collected to determine the plasma biochemical indices.[Result]The contents of dry matter,crude protein,methionine,lysine,and threonine in Zanthoxylum bungeanum residue were 90.16%,14.74%,0.10%,0.49%,and 0.34%,respectively.The apparent metabolizable energy and true metabolizable energy for ducks were 9.49 and 11.87 MJ/kg,respectively.The results of the feeding experiment showed that,compared with control group,dietary supplementation with 6%and 8%Zanthoxylum bungeanum residue significantly decreased the FBW,ADG,and ADFI of Sansui ducks(P<0.05),and dietary supplementation with 6%Lanthoxylum bungeanum residue significantly increased the F/G(P<0.05).Supplementation with 2%and 4%Zanthoxylum bungeanum residue significantly decreased the FBW and ADFI of Sansui ducks(P<0.05),but had no significant effects on ADG and F/G(P>0.05).Compared with control group,dietary supplementation with Zanthoxylum bungeanum residue(2%,4%,6%,and 8%)significantly decreased plasma aspartate aminotransferase(AST)activity(P<0.05),and significantly increased plasma uric acid(UA)content(P<0.05)in Sansui ducks.[Conclusion]In conclusion,Zanthoxylum bungeanum residue could be used as an unconventional feed resource in duck feed rations in a limited manner.Under this experimental conditions,the recommended addition amount of Zanthoxylum bungeanum residue in the diet of Sansui ducks aged 4 to 8 weeks of age should not exceed 2%.
