在西非萨赫勒地区，绵羊育肥在作物-牲畜混合系统中具有重要的经济意义。由于投资少、周转快，它对包括妇女在内的贫穷农民特别有吸引力。通过为期56天的饲养试验，确定了花生秆和谷糠对绵羊育肥的适宜饲养水平。48只Peul Oudah公羊，购自牲畜市场，约12-15个月大，平均初始活重20.3公斤（标准差= 1.7）被随机分成6只动物的组，并被分配到8个处理组，所述处理组由花生杆的4个饲养水平的析因组合来定义（每只动物每天0、300、600和900 g）和两个水平的小麦麸（每只动物每天0和400 g）。以40 g/kg活重自由采食灌木干草作为基础饲料。总干物质摄入量和可消化有机物摄入量与花生秆和谷糠水平呈线性相关。绵羊平均日增重（ADG）分别为-27.5，10.4，30.8和35.7 g/d。在谷糠400 g/d的条件下，四种水平花生秆的日增重分别为40.3、59.5、91.7和63.4 g/d。补充600克/天的花生杆和400克/天的小麦麸得到了最高的净回报。
Sheep fattening is economically important in mixed crop-livestock systems in the West African Sahel. It is particularly attractive to poor farmers including women because of the low investment and rapid turnover. A feeding trial was conducted for 56 days to determine the optimal feeding levels of groundnut haulms and millet bran for profitable sheep fattening. Forty-eight Peul Oudah rams, bought from a livestock market, about 12-15 months old, with an average initial live weight of 20.3 kg (standard deviation = 1.7) were randomly divided into groups of six animals and allotted to eight treatment groups defined by a factorial combination of four feeding levels of groundnut haulms (0, 300, 600 and 900 g per animal per day) and two levels of millet bran (0 and 400 g per animal per day). Bush hay was offered ad libitum at 40 g/kg live weight as basal feed. Total dry matter intake and digestible organic matter intake were linearly related to the level of groundnut haulms and millet bran offered. Average daily gains (ADGs) of sheep offered 0, 300, 600 and 900 g/day of groundnut haulms without millet bran were -27.5, 10.4, 30.8 and 35.7 g/day, respectively. With 400 g millet bran per day, ADGs were 40.3, 59.5, 91.7 and 63.4 g/day, for the four levels of groundnut haulms, respectively. Supplementation with 600 g/day of groundnut haulms and 400 g/day of millet bran gave the highest net return.
