【摘要】：我国肉兔养殖正处于传统养殖向集约化工厂养殖转型的关键阶段。本研究依托肉兔生产现状,对肉兔商品生产中饲料营养,养殖模式,同期发情技术,断奶体重和饲喂方式进行了系统研究,旨在提高肉兔养殖的规模化,节约化,现代化养殖水平,最终获得最大经济效益。饲料营养试验表明:全进全出养殖模式下伊拉繁殖母兔,可促进高繁母兔泌乳力的饲料蛋白含量是17~18%,能量需求范围是10.5MJ/kg~11 MJ/kg,纤维水平是13%左右,赖氨酸水平是1%左右。养殖模式对比试验表明:全进全出模式35日龄断奶成活率,70日龄育肥成活率皆极显著高于普通养殖模式(P0.01)。同期发情试验表明:种母兔同期发情最优光照处理为:配种前6d加光,每天光照16h,配种后7天减光;在进行加光配种的前提下,不注射激素,发情率依然保持较高水平。断奶体重对比试验表明:断奶体重越高,出栏重越大,越有利于经济效益的提升。饲喂方式试验表明:自由采食组合出栏体重极显著高于限制饲喂组(p0.01),料重比限制饲喂组(3.09)极显著低于自由采食组(4.04)(p0.01);只均收益自由采食组合要极显著低于限制饲喂组合,每只育肥兔少收益3.86元。不同限料量对仔兔成活率影响差别不大;出栏体重随着限制饲喂用料的减少呈减小趋势,合理范围的限制饲喂对育肥兔养殖效益的提升十分明显,在不同地区,不同品种,不同季节我们应该遵循不同的饲料饲喂标准饲喂育肥兔。
[Abstract]:The meat rabbit breeding in China is in the key stage of the transition from traditional breeding to intensive factory breeding. Based on the present situation of meat rabbit production, the feed nutrition, breeding mode and estrus technology in the production of meat rabbit were studied. The weaning weight and feeding methods were systematically studied in order to improve the scale, economization and modernization of the breeding of meat rabbits. Finally, the maximum economic benefit was obtained. The results of feed nutrition test showed that the feed protein content, energy demand range of 10.5MJ / kg / kg 11 mg / kg and fiber level about 13% were 170.18%, 10.5MJ / kg ~ 11 MJ / kg and 13% ~ (th), respectively. The lysine level was about 1%. The contrast experiment of breeding model showed that the survival rate of weaning at 35 days old and 70 days old was significantly higher than that of common breeding model P0.01.The estrus experiment showed that the female rabbits were in the same period. The best light treatment for estrus was: adding light 6 days before mating, The estrus rate remained at a high level without the injection of hormone. The weaning weight comparison test showed that the higher the weaning weight, the greater the outfall weight, the higher the weaning weight, the higher the weaning weight, the higher the weaning weight, the higher the estrus rate was, the higher the weaning weight was, the higher the weaning weight was. The experiment of feeding mode showed that the body weight of free feed combination was significantly higher than that of restricted feed group (P 0.01), and the ratio of feed to weight was 3.09) which was significantly lower than that of free feed group (4.04%), and the average income of free feed group was only lower than that of free feed group (P < 0.05). The combination was significantly lower than the restricted feed combination. Each fattening rabbit had less income of 3.86 yuan. The effect of different feed restriction on the survival rate of fattening rabbits was not significant. The weight of fattening rabbits decreased with the decrease of the limited feeding materials, and the benefit of fattening rabbits was obviously improved by limiting feeding in a reasonable range. In different regions, varieties and seasons, we should follow different feed standards to feed fattening rabbits.
