摘要
用齐卡新西兰兔、德国白兔与四川白兔的杂交兔 ,观测了不同料型 (颗粒料和粉料 )、不同规格 (直径 4mm和6mm)的颗粒料补饲仔兔的效果和对幼兔生长发育的影响 ,结果表明 :仔兔补饲及 70日龄前的幼兔宜饲喂直径 4mm的颗粒料。颗粒料补饲仔兔明显优于粉料 ,日增重 (30克 )显著 (P<0 0 5 )高于粉料组 (2 6克 ) ,饲料转化率亦高于粉料。 70日龄前的幼兔饲喂细颗粒料可明显提高增重 ,改进饲料报酬 ;而颗粒直径大小对 70日后的幼兔生长和饲料报酬已无明显影响 (P >0 0 5 )。不同料型和不同规格的颗粒料对仔兔成活率影响不显著 (P >0 0 5 )。
ZIKA New Zealand Rabbit and the crossing of German White Rabbit with Sichuan White Rabbit were used to survey the effcet of the shape of the feed (pellet and powder) and the size of the pellet(with the diameter of 4mm and 6mm) on the sucking rabbit which was supplemented with feed and the growing one.The results were as followed:(1)The pellet with the diameter of 4mm was the best for the sucking rabbits and the growing ones younger than 70-day.(2)Pellet was significantly better than powder for the sucking ones.There was significant difference between the ADGs(30g:26g)(P<0.05).And the feed efficiency of the pellet group was higher.(3)For the growing ones younger than 70-day,the small pellet improved the ADG and feed conversion rate significantly;while for those older than 70-day,.the effect of the size of pellet was not significant.(4)The effect of shape and size of feed on the survival rate of the sucking rabbits and growing ones was not significant(P>0.05).
