摘　　要：试验旨在研究甘蔗尾梢颗粒饲料对育肥牛、羊生长性能的影响。选取15~18月龄健康、体重接近的西门塔尔杂交一代牛30头,随机分为2组(每组3个重复,每个重复5头),选取8~10月龄健康、体重接近的马山黑山羊60只,随机分为2组(每组3个重复,每个重复10只):对照组饲喂企业自配混合粉料+草料,试验组饲喂甘蔗尾梢颗粒饲料+草料,预试期为7 d,正试期为60 d。结果表明:(1)育肥牛、羊试验组的末重(FBW)、平均日增重(ADG)、总增重、毛利润均显著高于对照组(P<0.05),料重比(F/G)显著低于对照组(P<0.05)。(2)育肥牛、羊试验组的平均日采食量(ADFI)差异不显著(P>0.05)。(3)育肥牛试验组比对照组F/G降低了26.72%,毛利润提高了409.68元;育肥羊试验组比对照组F/G降低了32.96%,毛利润提高了27.06元。由此可见,在牛羊育肥过程中,饲喂甘蔗尾梢颗粒饲料能显著提高牛羊的生长性能,提高经济效益。The experiment was conducted to study the effects of sugarcane caudate lobe pellet feed on growth performance of fattening cattles and sheeps. A total of 30 healthy 15-18-month -old Simmen- tal hybrid cattles with the similar body weight were randomly divided into two groups, and each group had three replicates with five eattles in each replicate. And a total of 60 healthy 8-10-month -old Mashan black sheeps with the similar body weight were randomly divided into two groups, and each group had three replicates with ten sheeps in each replicate. Fattening cattles and sheeps in the con- trol groups were fed self-made feed ＋ hay, and the others in experimental groups were fed sugarcane caudate lobe pellet feed ＋ hay. The experiment was 7 days for adaptation and 60 days for trial period. The results showed as follows： ① the final body weight（FBW）, average daily gain（ADG）, total weight gain, gross profit of fattening eattles and sheeps in experimental groups were significantly higher than that in control group （P〈0.05）, and the feed-gain ratio（F/G） in experimental groups was significantly lower than that in control group （P〈0.05）.② The average daily ence between control group and experimental group（P〉0.05）. gain（ADFI） was not significant differ- ence between control group and experimental group（P〉0.05）. ③ The feed-gain ratio of fattening catties was decreased by 26.72%, and the average gross profit increased 409.68 yuan; The feed- gain ratio of fattening sheeps was decreased by 32.96%, and the average gross profit increased 27.06 yuan. It was concluded that feeding sugar- cane caudate lobe pellet feed was able to im- prove the economic benefit and the production performance of fattening cattles and sheeps.
