Comparison of selected indices of internal environment and condition of laying hens kept in furnished cages and in aviaries

Popis výsledku v původním jazyce

Biochemical and hematological examination of blood and individual assessment of the birds were performed in Lohman Brown laying hens at 45 weeks of age housed in different systems. The biochemical examination revealed higher ( p &lt; .01) corticosterone levels, creatine kinase, and aspartate aminotransferase activity and lower (p &lt; .01) levels of lactate, triglycerides, albumin, calcium, and phosphorus in aviary hens compared to hens housed in furnished cages. Hematological examination of hens housed in aviaries revealed higher (p &lt; .05) hematocrit, leukocytes, heterophils, eosinophils, basophils, monocytes, and H/L ratio. Furthermore, hens housed in aviaries had lower (p &lt; .01) body weight than hens in furnished cages, they were worse feathered (p &lt; .001), had more damaged combs (p &lt; .05), and poorer physical condition (p &lt; .01). In contrast, caged hens showed worse (p &lt; .01) feather condition of the wings due to abrasion and claws due to overgrowth. The results have shown that the housing system has a significant impact on the internal environment and condition of birds and that housing in aviaries without taking into account the specifics of such housing may lead to significant stress and disturbance to the welfare of laying hens.
