Effects of fermented flammulina mushroom bran on growth performance,meat quality,and breeding cost of mutton sheep
试验旨在探讨不同水平发酵金针菇菌糠对肉羊生长性能、肉品质及养殖成本的影响.研究选择体重相近的健康湖羊60只,随机分为5组,每组12个重复,每个重复1只湖羊.各组分别添加0、10％、20％、30％和40％的发酵金针菇菌糠,等量替代基础饲粮中的全株玉米青贮.预试期7d,正式试验期60 d.结果显示,与对照组相比,饲喂20％和30％的发酵金针菇菌糠可以显著提高肉羊的末重和平均日增重(P＜0.05),显著降低料重比(P＜0.05).与对照组相比,饲喂20％和30％的发酵金针菇菌糠可以显著增加肉羊的胴体重、屠宰率、净肉重和净肉率(P＜0.05),显著提高肉羊的肌肉红度、熟肉率(P＜0.05),显著增加肌肉pH24h值及肌纤维密度(P＜0.05);饲喂20％的发酵金针菇菌糠可以显著降低肉羊肌肉滴水损失(P＜0.05);饲喂10％～40％的发酵金针菇菌糠可显著增加肉羊肌纤维面积(P＜0.05).饲喂发酵金针菇菌糠可以增加肉羊的增重收入,提高养殖利润.各发酵金针菇菌糠添加组肉羊的养殖利润分别比对照组提高了16.23％、41.52％、31.64％和2.19％.研究表明,肉羊饲粮添加适量的发酵金针菇菌糠可以改善其生长性能和肉品质,提高屠宰性能,降低养殖成本,增加养殖利润,发酵金针菇菌糠的适宜添加水平为20％.
The experiment aimed to explore the effects of different levels of fermented flammulina mushroom bran on the growth performance,meat quality,and breeding cost of mutton sheep.A total of 60 healthy Hu sheep with similar body weight were randomly divided into five groups,with 12 replicates per group and one Hu sheep per replicate.The mutton sheep in each group were fed a basic diet supplemented with 0,10％,20％,30％,and 40％fermented flammulina mushroom bran,respectively,substituting an equivalent amount for the whole-plant corn silage in the basic diet.The preliminary trial period was 7 days,and the formal trial period was 60 days.The results showed that compared with the control group,feeding 20％and 30％fermented flammulina mushroom bran significantly increased the final weight and average daily weight gain of mutton sheep(P＜0.05),and significantly reduced the feed-to-gain ratio(P＜0.05).Compared with the control group,feeding 20％and 30％fermented flammulina mushroom bran significantly increased the carcass weight,slaughter rate,net meat weight,and net meat rate of mutton sheep(P＜0.05),significantly improved the muscle redness and cooked meat rate(P＜0.05),significantly increased the muscle pH value at 24 hours and muscle fiber density of mutton sheep(P＜0.05).Feeding 20％fermented flammulina mushroom bran significantly reduced the muscle drip loss of mutton sheep(P＜0.05).Feeding 10％to 40％fermented flammulina mushroom bran significantly increased the muscle fiber area of mutton sheep(P＜0.05).Feeding fermented flammulina mushroom bran can increase the weight gain income of mutton sheep,improve breeding profitability,and the breeding profit of Hu sheep in each fermented flammulina mushroom bran group increased by 16.23％,41.52％,31.64％,and 2.19％compared to the control group.The study indicates that adding an appropriate amount of fermented flammulina mushroom bran to the diet of mutton sheep can improve the growth performance and meat quality,enhance the slaughter performance,reduce the breeding costs,and increase the breeding profit,with an optimal addition level of 20％.
