Effect of peanut seedling silage on growth performance,nutrient apparent digestibility,and economic benefit of mutton sheep
The study was to investigate the effect of peanut seedling silage on the growth performance,apparent nutrient digestibility,and economic benefit of mutton sheep.Sixty mutton sheep with similar body weight and good condition were randomly divided into four groups with 15 replicates per group and one sheep per replicate.The mutton sheep in the control group were fed a whole-plant maize silage diet,20%peanut silage was used instead of whole-plant maize silage in the experiment group 1,40%peanut silage was used instead of whole-plant maize silage in the experiment group 2,and 80%peanut silage was used instead of whole-plant maize silage in the experiment group 3.The experiment lasted for 60 days.The results showed that the feed to gain ratio of mutton sheep in each peanut seedling silage group was significantly lower than that in the control group(P<0.05),and the average daily gain was significantly higher than that in the control group(P<0.05).The apparent digestibility of crude protein and neutral detergent fiber in the experiment group 2 and experiment group 3 was significantly higher than that in the control group(P<0.05).The serum total protein level in the experiment group 2 and experiment group 3 was significantly higher than that in the control group(P<0.05),and the urea nitrogen and triglyceride levels,and the ALT activity were significantly lower than that in the control group(P<0.05).The profit of each peanut seedling silage group was higher than that of the control group,and showed an upward trend with the increase of peanut seedling silage dosage.The study indicates that peanut seedling silage can improve the growth performance and nutrient apparent digestibility of mutton sheep,improve serum biochemical indexes,and increase breeding profits.Considering comprehensively,it is more suitable to use 40%～80%peanut seedling silage in mutton sheep breeding.
