青绿饲草饲喂母兔效果分析

Analysis of the effect of forage grass on feeding female rabbit

通过用青绿饲草和全价配合饲料饲喂母兔，以比较母兔的繁殖性能和经济效益。结果表明，以青绿饲草为主饲喂的试验组和用配合料饲喂的对照组，产仔数分别为７０和７３只；仔兔初生窝重分别为（３７７４±５３８）ｇ和（４０１８±７３８）ｇ；断奶个体重分别为（４３２７±１０５）ｇ和（４４２８±９３）ｇ。两组的产仔数、初生窝重和断奶个体重经ｔ检验差异均不显著（Ｐ＞００５）。试验组仔兔断奶成活率和产母仔数的比例比对照组提高５２和６２个百分点；饲料费用每只母兔节约８１６元。

This experiment was carried out to analyse the effect of forage grass on the reproductive capacity and economic profit for female rabbits as well as to compare the observed effect with that of the usually used complete formula feed. The results showed that litter size at birth in the tested group fed with forage grass was 7 while in the contrast group fed with complete formula feed was 73; weaning individual weight in the tested group averaged (4327105) g,slightly lower than (4428+93) g in the contrast group; birth weight of litter in the former come to (3774538) g on the average while it numbered (4018738) g in the latter. It was observed that there existed almost no significant diffence ( P >005) whether in litter size at birth or in birth weight of litter or in weaning individual weight. However both survival rate of weaning rabbits and female ratio at birth in the tested group were respectively 52 percentage and 62percentage higher than those in the contrast group, thus 861 yuan (RMB) being saved
