1.对两种设计的鸡笼生产的鸡蛋的卫生性能进行了调查，并与两种标准的网箱设计进行了比较。在28周龄、37周龄、47周龄和58周龄时，其中一个网箱设计的脏蛋比例较高，而另一个网箱设计与标准网箱相似。在27、33和60周龄时，蛋壳上的细菌负荷(总需氧细菌和肠球菌)在配备笼子的设计中较高。观察到季节性效应，60周(冬季)的计数低于27周(夏季)。在巢外下蛋的鸡蛋中发现了更多的脏鸡蛋和更高的细菌负荷，这表明如果改进家具笼内的设备以加强下蛋，家具笼子中的鸡蛋卫生可以与标准笼子相似。
1. The hygienic properties of eggs produced in two designs of furnished cage were investigated and compared to two standard cage designs.2. At 28, 37, 47 and 58 weeks of age, the proportion of dirty eggs was higher in one of the furnished cage designs while, in the other, it was similar to standard cages.3. At 27, 33 and 60 weeks, the bacterial load on the eggshell ( total aerobic bacteria and enterococci) was higher in furnished cage designs. A seasonal effect was observed with lower counts at 60 weeks ( winter) than at 27 weeks ( summer).4. More dirty eggs and a higher bacterial load were observed in eggs laid outside the nests, which suggests egg hygiene in furnished cages could be similar to standard cages if the equipment in furnished cages was improved to enhance nest laying.
