Experiments were undertaken with Malawi zebu steers over three wet seasons to investigate the effects of feeding improved forages (zero grazed) and supplements on animal performance. The forages fed were Guinea grass and pearl millet and the supplements maize: madeya (maize bran) or maize: madeya: cottonweed cake. The daily allowance of supplement was, on a DM basis, liveweight equivalent to 0-6, 1-1 or 1-5 per cent of cattle (1973, 1974). In 1975 the supplementation treatments were nil, maize: madeya or leucaena fed at 0-6 per cent liveweight. Daily gains of steers were similar with both forages except in 1975 when those fed on pearl millet grew 19 per cent faster than those on Guinea grass. The performance of steers was increased with supplementation only where forage quality declined. The significance of the results are discussed.
在三个雨季期间，对马拉维瘤牛阉牛进行了试验，以研究饲喂改良牧草（零放牧）和补充饲料对动物生产性能的影响。所饲喂的牧草为几内亚草和珍珠粟，补充饲料为玉米：马德亚（玉米麸）或玉米：马德亚：棉籽饼。以干物质计，补充饲料的日供应量相当于牛体重的0 - 6%、1 - 1%或1 - 5%（1973年、1974年）。1975年，补充饲料处理为不补充、玉米：马德亚或银合欢，饲喂量为体重的0 - 6%。除1975年外，两种牧草喂养的阉牛日增重相似，1975年食用珍珠粟的阉牛比食用几内亚草的阉牛生长速度快19%。只有在牧草质量下降的情况下，补充饲料才会提高阉牛的生产性能。对结果的意义进行了讨论。
