A total of 768 female broiler chicks in two experiments was fed diets containing 0, 100, or 120 mg monensin/kg of diet with and without added animal fat, in a 2 X 3 factorial design. Chicks were grown in electrically heated battery brooders and supplied feed and water ad libitum for 21 days. Animal fat fed at 6.8% of the diet consistently improved body weight, daily feed intake, and feed conversion regardless of monensin level. Monensin at 100 and 120 mg/kg of diet, in general, decreased these performance criteria progressively. Daily monensin intake was related to the concentration of monensin in the diet. Intake per unit of body weight was increased by reducing fat or increasing monensin.
在两项试验中，共768只雌性肉鸡雏鸡被饲喂含有0、100或120毫克莫能菌素/千克日粮的日粮，日粮添加或不添加动物脂肪，采用2×3析因设计。雏鸡在电加热的育雏笼中饲养，自由采食和饮水21天。无论莫能菌素水平如何，以日粮的6.8%饲喂动物脂肪均能持续提高体重、日采食量和饲料转化率。日粮中添加100和120毫克/千克的莫能菌素通常会逐渐降低这些生产性能指标。每日莫能菌素摄入量与日粮中莫能菌素浓度有关。通过减少脂肪或增加莫能菌素可提高单位体重的摄入量。
