With 9 rats in each group, each group of three repeated, each 3 ram, the selected 24 ewes unified breeding period by B ultrasonic detection has been pregnant ewes. Through the process of captive experiment, digestion and metabolism experiment, research off detoxicated castor bean meal on function of sheep give birth, breeding function, economic benefit and effect on the rate of digestion of dietary, notes 1. In sheep fine estimation in 5%, 10%, 15% detoxicated castor bean meal, to replace the protein feed, stop 60 days in captivity in the experiment, each sheep health state is superior. Among the groups of sheep daily feed intake and average weight differences were not obvious (P "0. 05), the daily gain has the tendency to decrease. The feed conversion rate of the 10% detoxification castor meal group was the best, and the feed cost was lowest. 2. Digestion and metabolism experiment annotations, feeding off the detoxicated castor bean meal to the diet of sheep dry material, inorganic, always, crude protein, acid washing fiber surface not Ya digestibility and contrast group, the difference was not obvious (P 0. 05) the apparent digestibility of crude fat in the contrast group was significantly higher than that in other groups (P 0. 05). With the dcbm adding increase, crude protein digestibility showed a growth trend, energy accumulation rate decreased trend. The digestive energy and metabolism energy of the 10% and 15% detoxification castor meal group were significantly different from that of the control group (P 0. 05). 3. Feeding off the detoxicated castor bean meal of Sheep Semen quingity, add 10%, 15% off detoxicated castor bean meal group sperm motility, sperm density, sperm deformity rate and contrast group compared obvious difference (P < 0. 01). Detoxicated castor bean meal off the effects on the performance of ewe breed is not big, the group of single lambs uniform birth weight and contrast group compare difference not obvious (P 0. 05). 4. Feeding off the detoxicated castor bean meal group sheep serum total protein and albumin content were in the normal range, serum alanine aminotransferase were lower than 30U/l and between groups difference not obvious (P 0. 05), explain the dcbm of sheep liver injury. Comprehensive analysis, in the estimation of the sheep in the detoxification of castor meal to add the amount of the best 10%, in the ram fine estimation of the added amount of castor meal to 5% for good. 目录: 摘要 5-6 前言 6-13 1 蓖麻饼粕的价值 6-7 2 蓖麻饼粕的脱毒 7-8 3 脱毒蓖麻饼粕在实际生产中的运用 8-11 3.1 白鼠毒性试验 8 3.2 家禽的饲喂试验 8-9 3.3 猪的饲喂试验 9-10 3.4 反刍动物的饲喂试验 10-11 3.5 其他动物的饲喂试验 11 4 本探讨的目的、意义和内容 11-13 4.1 探讨目的 11 4.2 探讨意义 11-12 4.3 探讨内容 12-13 材料与措施 13-17 1 试验时间与地点 13 2 试验材料 13 3 试验动物和分组 13 4 试验日粮 13-14 5 饲养试验：动物的饲养与管理 14-15 6 消化代谢试验：样品的收集和处理 15 7 评价指标与检测措施 15-16 7.1 生产性能 15 7.2 消化代谢 15 7.3 繁殖性能 15-16 7.4 血液指标 16 8 数据统计与处理 16-17 结果与略论 17-27 1 饲养试验结果 17-19 1.1 脱毒蓖麻粕适口性及对绵羊健康状况的作用 17 1.2 饲喂脱毒蓖麻粕对绵羊生产性能的作用 17-18 1.3 饲喂脱毒蓖麻粕对经济效益的作用 18-19 2 消化与代谢试验结果 19-23 2.1 饲喂脱毒蓖麻粕对绵羊采食量及养分表观消化率的作用 19-20 2.2 饲喂脱毒蓖麻粕对绵羊能量和蛋白质代谢的作用 20-23 3 饲喂脱毒蓖麻粕对绵羊繁殖性能的作用 23-26 4 饲喂脱毒蓖麻粕对绵羊血清成分的作用 26-27 讨论 27-31 1 饲喂脱毒蓖麻粕对绵羊生产性能及经济效益的作用 27-28 2 饲喂脱毒蓖麻粕绵羊对各种养分消化代谢的作用 28-29 3 饲喂脱毒蓖麻粕对绵羊繁殖性能的作用 29 4 饲喂脱毒蓖麻粕对绵羊血清成分的作用 29-31 结论 31-32 参考文献 32-35 英文摘要 35 致谢 36 |
