In order to investigate the effect of different levels of oral glucose supplementation and/or reproductive method on productive and reproductive performance of New Zealand White (NZW) doe rabbits in the tropic, 36 bucks and 120 doe NZW rabbits were equally divided among four treatment groups (n = 9 bucks + 30 does). The treatments consisted of supplementing drinking water with 0 (control), 2.5, 5 and 10 g glucose/l, respectively. To study the effect of reproduction method (natural v. artificial), each group was divided into two sub-groups (naturally mated and artificially inseminated) with the same bucks of the same treatment group. Glucose supplementation at 5 or 10 g/l of water increased (P < 0.01) litter weight at birth and at weaning, and litter weight gain during the 4 weeks. However, glucose supplementation at 2.5 or 5.0 g/l water decreased (P < 0.01) feed consumption from 7 to 14 days after delivery. Glucose supplementation at 2.5 g/l water did not affect productive and reproductive performance of rabbits. Artificially inseminated does had higher daily litter weight gain between 21 and 28 days post partum. Artificially inseminated group had better milk conversion during the 1st and 4th week as compared to naturally mated groups. Compared with the control group, the economic efficiency and performance index of NZW rabbits was significantly improved by 5 g glucose supplementation under tropic condition.
为了研究不同水平的口服葡萄糖补充和/或繁殖方法对热带新西兰白兔(NZW)母兔生产和繁殖性能的影响,36 只公兔和 120 只母兔 NZW 被平均分配到四个处理组(n = 9 只公兔+30 只母兔)。处理组分别在饮水中补充 0(对照)、2.5、5 和 10 g/L 葡萄糖。为了研究繁殖方法(自然交配与人工授精)的影响,每组又分为两个亚组(自然交配和人工授精),每个亚组使用相同处理组的相同公兔。在水中补充 5 或 10 g/L 葡萄糖增加了(P < 0.01)初生和断奶时的窝重以及 4 周内的窝重增长,但在水中补充 2.5 或 5.0 g/L 葡萄糖降低了(P < 0.01)从分娩后 7 天到 14 天的饲料消耗。在水中补充 2.5 g/L 葡萄糖对兔子的生产和繁殖性能没有影响。人工授精的母兔在产后 21 至 28 天的每日窝重增长更高。与自然交配组相比,人工授精组在第 1 周和第 4 周的牛奶转化率更高。与对照组相比,在热带条件下,每只母兔添加 5 g 葡萄糖可显著提高新西兰白兔的经济效益和生产性能指数。
