Effects of dietary concentrate-to-roughage ratio under unconventional feed combination on growth performance,rumen fermentation,and economic benefits of fattening Hu sheep
摘要
Abstract
This experiment aimed to investigate the effects of different dietary concentrate-to-roughage ratios under unconventional feed combination on the growth performance,nutrient apparent digestibility,rumen fermentation parameters,and economic benefits of fattening Hu sheep.A total of 54 healthy male Hu lambs with a body weight of(19.31±0.55)kg were randomly divided into three groups,with three replicates per group and six sheep per replicate.Groups Ⅰ,Ⅱ,and Ⅲ were fed total mixed rations with concentrate-to-roughage ratios of 50∶50,60∶40,and 70∶30,respectively.The pre-test period was 10 days,and the formal test period was 60 days.The results showed that the final body weight and average daily feed intake in the groups Ⅱ and Ⅲ were significantly higher than those in the group Ⅰ(P<0.05).The average daily gain in the group Ⅲ was significantly higher than that in the group Ⅰ by 16.08%(P<0.05).The apparent digestibility of dry matter,crude protein,and crude fat in the group Ⅲ were significantly higher than that in the groups Ⅰ and Ⅱ(P<0.05).The apparent digestibility of neutral detergent fiber in the group Ⅲ was significantly higher than that in the group Ⅰ(P<0.05).The acetate/propionate in the group Ⅲ was significantly lower than that in group Ⅰ(P<0.05).The economic benefit in the group Ⅲ was higher than that in the groups Ⅰ and Ⅱ by 11.85%and 10.22%,respectively(P>0.05).The study shows that dietary concentrate-to-roughage ratio of 70∶30 can effectively improve the growth performance and economic benefits of fattening Hu sheep.关键词
