    摘要:

    为了满足新建蛋鸡场快速运转并减少投资成本,提高生产性能,本试验对不同饲养密度条件下蛋鸡成活率、体重和均匀度进行比较。试验选用966 750只蛋鸡,采用层叠笼养方式,分两个试验组,A组为低密度试验组,每笼养18只,B组为高密度试验组,每笼养28只,从成活率、体重、均匀度进行比较分析。结果表明:蛋鸡60日龄成活率和105日龄成活率,试验B组显著高于试验A组(P<0.05);第四周、第六周试验A组体重显著高于试验B组(P<0.05),第十四周试验B组体重显著高于试验A组(P<0.05),其余均差异不显著(P>0.05);各周均匀度均差异不显著(P>0.05)。本文通过比较不同饲养密度得知,蛋鸡的成活率、体重以及均匀度均受到影响,但高密度组可单一鸡舍一次性多育成39 000 只蛋鸡,从而实现了蛋鸡规模化养殖,达到减少成本提高利润的目的。

    Abstract:

    In order to meet the requirement of rapid operation of new laying hens farm, reduce investment cost and improve production performance, the survival rate, weight and evenness of laying hens under different stocking densities were compared. 966 750 laying hens were selected in the experiment, which were divided into two groups.Group A was low-density group with 18 hens per cage, and group B was high-density group with 28 hens per cage.The survival rate, weight and evenness were compared and analyzed. The results showed that the survival rate of laying hens at 60 days and 105 days in group B were significantly higher than that of group A(P < 0.05). The body weight of group A was significantly higher than that of group B at the fourth and sixth weeks(P < 0.05). The body weight of group B was significantly higher than that of group A at the 14 th week(P < 0.05). There was no significant difference in the evenness of each week(P > 0.05). By comparing different stocking densities, we found that the survival rate, weight and evenness of laying hens were all affected. However the high-density group can independently breed more than 39,000 layers, thus to realize the large-scale breeding of laying hens and reducing costs and increasing profits.
