Beef fattening experiments were undertaken on the Lilonge Plain with Malawi zebu (Mz) and Friesian X Malawi zebu (F X Mz) steers. Animals were fattened under various dietary regimes based on either green forage crops or crop residues supplemented with concentrate rations of local origin. Mz steers consumed less feed and liveweight gain was approximately 75 per cent that of the F X Mz. Measurement of the efficiency parameters of feed conversion, gain and carcass yield per unit of liveweight revealed no significant differences between the two breed types. Slaughter observations indicated better fat distribution in the F X Mz and a significantly higher proportion of hindquarter. The significance of the results is discussed.
在利隆圭平原对马拉维瘤牛（Mz）和弗里斯兰×马拉维瘤牛（F×Mz）阉牛进行了育肥试验。动物在不同的日粮制度下育肥，日粮要么是绿色饲料作物，要么是补充了当地来源精饲料的作物残渣。Mz阉牛消耗的饲料较少，活重增加量约为F×Mz阉牛的75%。对每单位活重的饲料转化率、增重和胴体产量等效率参数的测量表明，两种品种类型之间没有显著差异。屠宰观察表明，F×Mz阉牛的脂肪分布更好，后躯比例显著更高。讨论了结果的意义。
