Housing and Illumination of Laying Hens

Abstract

In the frame of the long time research work the indoors-microclimatic conditions were measured together with the general parameters of egg production (feed consumption and conversion, eggs production and quality, etc.) in experimental building. The main indoors parameters (air temperature and relative humidity, air velocity, carbon dioxide, oxygen and ammonia concentrations, illumination and noise level) were measured during the summer, autumn and winter periods. Attention was paid to the problems of laying nests and illumination in relation to the quantity and quality of egg production. The obtained results from the experiments increased the knowledge about microclimatic conditions in egg production and help us to choose the suitable system for the future farms.
