摘要: 肉种鸡通过三段制笼养与地面平养对比试验结果表明,0~6周龄成活率笼养比平养高3.12%(P<0.01),7~23周龄成活率笼养比平养高5.9(P<0.01),23周龄体重整齐度笼养比平养高17.2%(P<0.01),24~68周龄存活率笼养比平养高2.45%(P<0.05),0~68周龄耗料量笼养比平养少消耗5.0kg,68周龄产蛋量笼养比平养平均多产2.7枚/只(P<0.05),种蛋合格率笼养比平养高0.1%(P>0.05),种蛋受精率笼养比平养高8%。Abstract: By comparing the cage rearing of three-stage type with floor rearing,the results showed that the cage rearing survival rates of 0~6 week-old chicken,7~23 week-old chicken and 24~68 week-old chicken were 3. 12%(P<0. 01),5. 9%(P<0. 01),and 2. 45%(P<0. 05) higher than floor rearing respectively. The regularity of 23 week-old chicken body weight was 17. 2% higher than floor rearing (P<0. 01). The feed consumption of 68 week -old chicken was 5.0kg less than floor rearing. The laying amount of 68 week-old chicken was 2. 7 egg/hen (P<0. 05) and the rate of certified egg was 0.1% higher than floor rearing (P>0. 05). The fertility rate of the egg was 8% higher than floor rearing.
