The effect of the replacement of corn with the liquid residue of cassava was evaluated at levels of 0, 25, 50, 75, and 100% in the diets of sheep on the intake and nutrient digestibility, weight gain, and carcass characteristics. Forty non-castrated crossbred Santa Ines sheep at 4 months of age and an initial body weight of 19.5 ± 2.5 kg were slaughtered after 90 days at the feedlot. A quadratic effect was found for intake of dry matter (DM), organic matter (OM), non-fiber carbohydrates (NFC), and digestible OM, with estimated values of 1130, 1080, 558, and 777 g/day at 11.2, 11.9, 30.8, and 2.18% of replacing corn with liquid residue of cassava, respectively. However, the intake of crude protein (CP) and neutral detergent fiber (NDF) decreased linearly around 105 to 45.3 g CP/day and 413 to 284 g NDF/day. The same effect was found for digestibility of DM (715 to 649 g/kg), OM (725 to 669 g/kg), CP (801 to 759 g/kg), and NDF (486 to 379 g/kg), which decreased linearly as the dietary liquid residue of cassava increased. The maximum average daily gain (174 g/day) was estimated with a 22.4% replacement level. Liquid residue of cassava can replace up to 25% of the corn in the diets of sheep, since it was possible to obtain a gain above 100 g/day, which is considered to be satisfactory.
在绵羊日粮中，用木薯液渣替代玉米，替代水平分别为0%、25%、50%、75%和100%，评估其对绵羊采食量、养分消化率、体重增加和胴体特性的影响。40只4月龄、初始体重为19.5±2.5 kg的非去势杂交圣伊内斯绵羊，在饲养场饲养90天后屠宰。发现干物质（DM）、有机物（OM）、非纤维碳水化合物（NFC）和可消化有机物的摄入量呈二次效应，用木薯液渣替代玉米的比例分别为11.2%、11.9%、30.8%和2.18%时，估计值分别为1130、1080、558和777 g/天。然而，粗蛋白（CP）和中性洗涤纤维（NDF）的摄入量呈线性下降，分别从约105 g CP/天降至45.3 g CP/天，从413 g NDF/天降至284 g NDF/天。DM（715至649 g/kg）、OM（725至669 g/kg）、CP（801至759 g/kg）和NDF（486至379 g/kg）的消化率也有同样的效应，随着日粮中木薯液渣的增加呈线性下降。替代水平为22.4%时，估计最大平均日增重为174 g/天。木薯液渣可替代绵羊日粮中高达25%的玉米，因为有可能获得高于100 g/天的增重，这被认为是令人满意的。
