利用皇竹草和抽穗期玉米秸秆青贮料作为能繁母牛、育肥牛的主要青粗饲料开展对比试验。通过120 d饲喂对比试验,饲喂2种不同饲料的能繁母牛受胎率分别为70.37%和76.92%,说明皇竹草和抽穗期玉米秸秆青贮料饲养能繁母牛对其受胎率无明显影响(P>0.05)；育肥牛的日增重分别为1294 g/d和1320 g/d,表明利用皇竹草和抽穗期玉米秸秆青贮料育肥肉牛,其生长速度无明显差异(P>0.05)。由于皇竹草在低海拔喀斯特山区易于种植,生长期长,产量高,易于加工和青贮,是低海拔喀斯特山区解决肉牛产业发展中青粗饲料来源的有效途径,适宜大面积推广应用。

In order to study the feeding effect of Pennisetum hydridum and corn straw mixed silage to breeding cattle, fattening cattle, the team con-ducted a comparative feeding experiment, a total of 120 days. The results showed that, two groups of experimental cattle conception rate were:72. 22%, 76. 92% (P>0. 05), that mixed silage can not affect conception rate of breeding cattle; two groups of fattening cattle daily gain are respectively:1 294 g/d, 1 320 g/d (P>0. 05), that mixed silage can not affect the growth of fattening cattle. Conclusion, Pennisetum hydridum long growth period, high yield, easy processing and silage, it is an important source of beef cattle feed low elevation mountains green and coarse fodder, suitable for large area popularization.
