Effects of dietary supplementation with co-culture probiotics and ferments and coated sodium butyrate on growth performance and economic efficiency in meat goslings
摘要
Abstract
To investigate the effects of co-culture probiotics and ferments and coated sodium butyrate on the production performance and economic benefits of meat goslings,this experiment adopted a 2x2 factorial design.A total of 1200 geese were randomly assigned to four dietary treatments(6 replicates per treatment)in a 35-day trial.Four trial group were:(1)control group(basal diet);(2)co-culture probiotics and ferments group(basal diet+500 mg/kg co-culture probiotics and ferments);(3)coated sodium butyrate group(basal diet+500 mg/kg coated sodium butyrate);and(4)combination group(basal diet+500 mg/kg co-culture probiotics and ferments+500 mg/kg coated sodium butyrate).Results showed that:Neither co-culture probiotics and ferments nor coated sodium butyrate significantly affected gosling body weight(P＞0.05),though numerical increases of 76 g(2.99％),112 g(4.41％),and 141 g(5.55％)were observed in the co-culture probiotics and ferments,coated sodium butyrate,and combination groups,respectively,compared with control group.Analysis revealed marginally significant interactive effects between co-culture probiotics and ferments and coated sodium butyrate for both feed intake(P=0.094)and feed conversion ratio(P=0.059).Specifically,the co-culture probiotics and ferments group showed significantly improved feed conversion ratio(P＜0.05;decreased by 0.25,12.25％)and a tendency for reduced feed intake(P=0.052;decreased by 518 g,10.03％)compared with control group.Additionally,both co-culture probiotics and ferments and combination treatments significantly enhanced survival rates(P＜0.05;increased by 0.90 percentage point and 0.92 percentage point respectively).Economic analysis revealed:Compared with control group,the co-culture probiotics and ferments,coated sodium butyrate,and combination groups showed increased gross profit per gosling(2.45,1.86,2.32 CNY),reduced production costs(0.63,0.24,0.29 CNY/kg),and improved European Production Efficiency Index(64,34,and 49 points),respectively.Dietary supplementation with either co-culture probiotics and ferments or coated sodium butyrate,individually or in combination,improved both production performance and economic returns in goslings.The combination treatment achieved optimal weight gain,while co-culture probiotics and ferments alone provided the best feed conversion efficiency and economic benefits.关键词
