摘要
为了研究白灵菇菌糠对肉牛适口性、生长性能、经济效益的影响,选择了40头日增重和体重接近的西门塔尔杂交二代牛,按体重配对原则分为对照组(CG)、试验Ⅰ、Ⅱ、Ⅲ组,分别用白灵菇菌糠代替日粮中0,20%,40%,60%的麦秸,进行70 d育肥试验。结果表明:试验组肉牛的日增重分别比对照组提高了1.59%,10.32%和2.38%,但差异不显著(P>0.05);采食速度分别比对照组提高了12.82%,7.69%(P>0.05),38.46%(P<0.01);料重比比对照组下降了1.56%,9.35%和2.33%;每千克增重的成本比对照组节约了2.33%,10.77%和4.61%;盈利分别比对照组提高了3.66%,16.92%和7.24%;其中均以40%组的效果最好。证明了白灵菇菌糠适口性好,可以做为反刍动物的饲料进行发开利用。
In order to research the influence of spent mushroom substrate of Pleurotus Nebrodensis on growth performance,palstability and profit on beef cow.Forty crossbred Simmental bulls were divided into four groups for 70 days finishing trial of different spent mushroom substrate（SMS） of Pleurotus Nebrodensis level replace wheat straw,control group,groupⅠ,Ⅱ and Ⅲ were fed with 0,20%,40%,60% SMS instead of wheat straw,respectively.The result showed that compare with control group the average daily gain in groupⅠ,Ⅱ and Ⅲ were slightly increased 1.59%,10.32%,2.38%（P〉0.05）,respectively;the speed of intake were also inhanced 12.82%,7.69%（P〉0.05）,38.46%（P〈0.01）,respectively;the ratio of feed and gain were reduced 1.56%,9.35% and 2.33% respectively;the cost of gain were declined 2.33%,10.77% and 4.61% respectively;the profit of weight gain were remarkable increased 3.66%,16.92% and 7.24% respectively.The result proved that SMS of Pleurotus Nebrodensis can be explored and used as ruminants feed.
