Effects of Restricted Basal Diet and Supplemented with Hydroponic Barley Seedling on Growth Performance,Slaughter Traits,Viscera Indexes and Serum Biochemical Indexes of Zi Geese
This experiment was conducted to explore the effects of restricted basal diet and supplemented with hydroponic barley seedling on growth performance,slaughter traits,viscera indexes and serum biochemical in-dexes of Zi geese.One hundred and sixty Zi geese at 28 days of age were randomly divided into 4 groups with 4 replicates in each group and 10 geese in each replicate.Geese in group A were provided a basal diet ad libi-tum without hydroponic barley seedlings.Geese in groups B,C and D were fed 85.0％,72.5％and 60.0％of the basal diet fed in group A,respectively,and hydroponic barley seedlings were provided ad libitum.The ex-periment lasted for 42 days.The results showed as follows:1)Zi geese in groups A and B had significantly higher total gain(TG)and average daily gain(ADG)than those in groups C and D(P＜0.05).Zi geese in group B had significantly higher final body weight(FBW)than that in groups C and D(P＜0.05).The cost of weight gain per kilogram in group B was the lowest.2)Zi geese in groups A and B had significantly higher ab-dominal fat rate than that in group D(P＜0.05).Zi geese in group A had significantly higher carcass rate than that in groups C and D(P＜0.05),and had significantly higher half net carcass rate and lean meat rate than those in group C(P＜0.05).Zi geese in group B had significantly higher carcass rate and chest muscle rate than those in group D(P＜0.05),and had significantly higher lean meat rate than that in groups C and D(P＜0.05).3)Zi geese in group A had significantly higher liver index and lower gizzard index than those in group D(P＜0.05).4)The serum albumin(ALB)content of Zi geese in groups A and B were significantly higher than those in groups C and D(P＜0.05).Zi geese in group A had significantly higher serum alanine transami-nase(ALT)and creatine kinase(CK)activities than those in groups C and D(P＜0.05),had significantly higher serum glucose(GLU)content than that in groups B and D(P＜0.05),and had significantly lower ser-um total bilirubin(TB)content than that in groups C and D(P＜0.05).Zi geese in group B had significantly higher serum triglyceride(TG)and total protein(TP)contents than those in groups C and D(P＜0.05).It is concluded that,in growing period of Zi geese,feeding 85.0％basal diet with ad libitum feeding of hydroponic barley seedlings can obtain the better feeding effect.[Chinese Journal of Animal Nutrition,2024,36(1):332-339]
