| Abstract | ||||
| The research aims to study the effect of different climatic factors (temperature, relative humidity, intensity of gases- NH3 & SO2) in layers hens houses, on the productive parameters for Hybird (Lohman). The research was carried out in a house for breeding layers parents in Deir Ezzour governorate in Syria from February 2007 to June 2008. The results of the research showed that the studied microclimatic parameters in houses of layers during the seasons of the year, a great effect in the productive characters, was reflected positively on the performance (production and quality) characters of layer birds, in spite of that the mean values surpassed the allowed limits as temperature in summer, which was over (30) C compared to the natural average (15 – 27) C, and the relative humidity in autumn and winter which reached a higher level than (60 – 70) %. Also the results of the research show that the quality of producing eggs is considered on the productive characters which is influenced greatly by microclimatic conditions, where as we find that the index of egg's shape is considered the least traits influenced by environment, and it's linked greater with the genotype than microclimate. While the sexual maturity and the eggs weight are influenced by a strong link between genotype – environment. | ||||
