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
摘要
Abstract
[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%.关键词
