发酵玉米秸秆在山羊养殖应用及饲喂效果观测

Fermentation of corn stalk in the goat breeding and feeding in the application of the effect of observation

在南方农区开发玉米秸秆养羊是解决山羊圈养饲草问题,增加收入的有效办法。我县于近年在有条件的山羊户中应用推广了玉米秸秆微生物发酵养羊,并选择一个大户开展了EM原露发酵玉米秸秆饲喂效果观测。试验表明:试验组(发酵玉米秸秆+精料)比对照组(未发酵玉米秸秆+精料)日增重高34.8克,提高39%【差异极显著(p<0.01)],只平获利比对照组多28.8元,提高50%,效果十分显著。试验Ⅱ组(青料+精料)只平增重比对照组和试验Ⅰ组高,但增重成本比试验Ⅰ组高,只平获利比试验Ⅰ组约低。未发酵玉米秸秆单独喂羊利用率低,发酵玉米秸秆饲喂山羊适口性好,利用率可达90%以上。

The development of rural areas in the southern corn stalk captive sheep goats forage to solve the problem, an effective way to increase revenue,Our county in recent years in the conditional application of the promotion of goat farmers in the corn stalk fermentation sheep, and select a large EM carried out the original open fermentation observing the effect of feeding corn stalks. Experiments show that： Test Ⅰ group （fermented corn straw ＋ concentrate） than the control group （non fermented corn straw ＋ concentrate） 34.8 grams of high average daily gain, to increase 39% [significant difference （p 〈0.01）], only to be fiat Libby 28.8 yuan more than the control group, 50 percent raise, the effect is very remarkable. Test Ⅱ group （green feed ＋ concentrate） only ping weight than the control group and experimental group Ⅰ, but the cost of weight gain was higher than in Experiment Ⅰ, only the profit level than the test Ⅰ group about. Fermentation of corn stover is not alone a low utilization rate to feed the sheep, goat feeding fermented corn stalk palatability, and the utilization rate of up to 90%.
