【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(P0.05),料重比(F/G)显著低于对照组(P0.05)。(2)育肥牛、羊试验组的平均日采食量(ADFI)差异不显著(P0.05)。(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。
[Abstract]:The purpose of the experiment was to study the effect of sugarcane tail pellet feed on the growth performance of finishing cattle and sheep. Thirty Simmental crossbred cows aged 15-18 months were randomly divided into two groups (3 replicas in each group, 5 in each), and 60 Mashan black goats aged 8-10 months were selected, whose weight was close to that of Maishan Black Goats, which were healthy from 8 to 10 months old, and were divided into two groups at random (3 replicas in each group, 5 in each). Two groups were randomly divided into two groups (each group of 3 replicas, each of 10): the control group was fed with enterprise-made mixed powder forage, and the test group was fed with sugarcane tail pellet forage for 7 days and 60 d for the positive test period and the pre-test period for 7 days and 60 d for the positive test period and the pre-test period for 7 days. The results were as follows: (1) the average daily gain of (FBW), and gross profit of finishing cattle and sheep test group were significantly higher than that of control group (P0.05), and the average daily gain of (ADG), was significantly higher than that of control group (P0.05). The feed-to-weight ratio (F / G) was significantly lower than that of the control group (P0.05). (2), and the average daily feed intake (ADFI) of the sheep test group was not significantly different (P0.05). (3). The average daily feed intake of the fattening cattle group was 26.72% lower than that of the control group (P 0.05). (3). Gross profit increased by 409.68 yuan; Compared with the control group, the fattening sheep in the test group decreased by 32.96% and the gross profit increased by 27.06 yuan. It can be seen that during the fattening process of cattle and sheep, the growth performance and economic benefit of cattle and sheep can be significantly improved by feeding the grain feed at the tail tip of sugarcane.
