摘　　要：试验研究添加糖蜜的全价混合颗粒饲料对育肥肉羊生长性能、血清生化指标以及经济效益的影响。选择3月龄、体重约25 kg、健康无病的寒蒙杂交公羔40只,随机分为2组,每组5个重复,每个重复4只羊。Ⅰ组试验羊饲喂全价混合粉料;Ⅱ组试验羊饲喂使用2%糖蜜代替Ⅰ组配方中2%玉米籽粒的全价混合颗粒饲料。试验期100 d。结果显示:与饲喂粉料相比,饲喂含糖蜜颗粒饲料的育肥肉羊采食量显著提高(P<0.05),日增重提高16.32%,血清中尿素氮降低12.00%,经济效益显著提高。研究表明,使用添加糖蜜的颗粒饲料饲喂肉羊可以有效减小劳动强度,降低粉尘污染,提高饲料利用率,获得更好的经济效益。The experiment was to study the effect of self-made full price mixed pellet feed with molasses on growth performance,serum biochemical indexes and benefit of fattening mutton sheep.40 three-month-old healthy Han and Mongolian crossbred male lambs with an average body weight of about 25 kg were randomly divided into two groups,with five replicates in each group and four lambs in each replicate.The sheep in groupⅠwere fed with full price mixed powder.Sheep in groupⅡwere fed with a complete mixed pellet feed with 2%molasses instead of 2%corn grains in the formula of groupⅠ.The experiment lasted for 100 d.The results showed that compared with feeding powder,the feed intake of fattening sheep fed with molasses pellets significantly increased(P<0.05),the daily weight gain increased by 16.32%,the serum urea nitrogen decreased by 12.00%,and the sales benefit was significantly improved.The study indicates that feeding mutton sheep with molasses-added pellet feed can effectively reduce labor intensity,reduce dust pollution,improve feed utilization and obtain better benefits.
