Effect of Dietary Concentrate to Forage Ratios on Growth Performance and Blood Biochemical Indexes of Hainan Black Goat
摘要
Abstract
The experiment was conducted to investigate the effect of different dietary concentrate to forage ratios (C/F) on the growth performance,biochemical indexes and economic benefits of Hainan black goats.Thirty growing goats with 10 kg body weight were divided into 6 groups with 5 goats in each group and provided 6 different diets:control (concentrate and forage feeding separately),different C/F total mixed ration(TMR) group (40 ∶ 60,45 ∶ 55,50 ∶ 50,55 ∶ 45,60 ∶ 40) and the experiment lasted 30 d.The results showed as follows:TMR treatments significantly increased the ADG and TG,but decreased F/G (P＜0.05).Diet treatments did not affect ADFI of goats (P＞0.05).For 40 ∶ 60 C/F group,the highest was ADG and TG while the lowest F/G.There were no significant differences among ALB,ALT,AST and ALP in 6 groups (P＞0.05),but dietary treatments had different effects on TPROT,GLB,CHOL,TRIG,Urea and GLU (P＜0.05).TMR treatments improved the net profit and input-output ratio,the 40 ∶ 60 C/F group displayed the best economic benefit.Based on this experiment,considering the growth performance,biochemical indexes and economic benefits,TMR treatment was better than the control,and the appropriate C/F was 40 ∶ 60 to growing Hainan black goats.关键词
