【摘要】：为比较笼养模式与散养模式对地方鸡种产蛋性能和蛋品质的影响,以北京地区的绿壳蛋鸡为研究对象,将该鸡种雏鸡笼养至16周龄后分为笼养组和散养组两个群体进行饲养,除饲养模式外其他条件均相同。分别记录两个鸡群的产蛋性能,并于30、35、40周龄时检测两鸡群的蛋品质,对收集的数据进行比较分析。结果表明,散养方式降低了绿壳蛋鸡的产蛋性能,具体表现在:散养组平均产蛋率比笼养组低21.54%;笼养组料蛋比为2.69,散养组则高达7.48。在蛋品质方面,散养使脏蛋率上升、破蛋率下降,对蛋壳品质和化学组成指标影响不大,蛋黄颜色有所加深,而蛋白高度和哈夫单位有所下降。因此,养殖场在选择养殖模式时,应综合考虑产品特点、消费市场等各方面因素,根据需求选择相应的养殖方式。
[Abstract]:In order to compare the effects of cage rearing model and free-range rearing model on the performance and quality of eggs of local chickens, the green shell laying hens in Beijing area were selected as the research objects. The chicks were divided into two groups after caged to 16 weeks of age: caged group and free-range group. All the conditions were the same except for the feeding mode. The egg performance of two flocks was recorded and the egg quality of the two flocks was tested at the age of 30 ~ 35 ~ 40 weeks, and the collected data were compared and analyzed. The results showed that the laying performance of green shell laying hens was decreased by the way of loose rearing. The average laying rate of the group was 21.54 lower than that of the cage group, the ratio of feed to egg was 2.69, and that of the rest group was as high as 7.48. In the aspect of egg quality, the rate of egg break decreased and the rate of egg break increased, the egg yolk color deepened, and the protein height and Hafu unit decreased, but the egg shell quality and chemical composition index were not affected. Therefore, when selecting the breeding mode, the breeding farm should take into account the characteristics of the products, the consumption market and other factors, and select the corresponding breeding methods according to the demand.
