Abstract
The study was conducted in 8 layer farms of Manikgong and 2 layer farms of Gazipur for two months to assess the environmental effect on layer performance. A significant inverse effect of high temperature on feed consumption egg productions as well as egg shell thickness was observed. However, there was not so significant effect of humidity on those parameters. On the other hand, at 3000ppm CO2 and 37ppm NH3, due to combined effect, feed c consumption and egg weight were decreases significantly but not such impact on egg shell thickness.
