不同类型玉米秸秆处理方式及饲喂肉牛效果观测

目的]为有效解决冬春季牛羊饲草料供给不足的问题,提高养殖综合效益。方法]本试验采用全株玉米戴穗青贮、鲜玉米秸秆青贮、干玉米秸秆微贮和干玉米秸秆黄贮等4种不同的玉米秸秆处理方式,并进行饲喂肉牛试验。试验结果]表明,经90d育肥,饲喂全株玉米戴穗青贮、鲜玉米秸秆青贮、微贮、黄贮的肉牛头均日增重分别为1 109.78g、1 010.89g、955.29g和955.74g,头均纯收益分别为1134.9元、1030.5元、1026.9元和1018.8元,分别较饲喂未处理干秸秆的肉牛多增收326.9元、222.3元、218.7元和210.6元,增重效果和经济效益十分显著。结论]全株玉米带穗青贮饲料可显著提高肉牛的增重速度和养殖效益,可全面推广普及。

Five Different Kinds of Corn Stover Treatments and Their Feeding Effects on Beef Cattle

Objective]To solve the shortage of cattle forage supply problems and to improve the com- prehensive benefit of farming. Method]This study used four methods to treat the corn stakles, namely, the whole plant corn taking ear ensiling storage, fresh corn stalks ensiling storage, dried corn stalks rub storage and dried corn stalks yellow storage. Then, they was used to take a test of feeding beeves. results]It showed that after 90 days cattle fattening, the cattle had got the daily gain weight for 1 109.78 g,1 010.89 g,955.29 g and 955.74 g,respectively and got the net income per head for 1134.9 yuan, 1030.5 yuan, 1026.9 yuan and 1,018.8 yuan by using above four methods and different storage methods. Compared with the untreated dried straw fedding beef, the four methods increased 326.9 yuan, 222.3 yuan, 218.7 yuan and 210.6 yuan, which significantly increased in gaining weight and economy benefit. Conclusion]Using the whole plant corn taking ear ensiling storage could significantly improve the speed of weight increasing and breeding income, which was suggested to widely use in the practice.
