Abstract

The main objective in brooding is to efficiently and economically provide a comfortable, healthy environment for growing birds. Bird's age is a governor factor to determine the heating load for broiler housing particularly during winter season. Forced air heating system should be put the broiler in thermal comfortable zone to obtain the higher production. Therefore, using perforated polyethylene duct to improve this heating system may cause better thermal conditions inside the broiler housing by reducing the temperature stratifications. So that the experiment was conducted out in private broiler house during winter season of 2011, under the climatic conditions of middle area of coastal Delta, Egypt (latitude and longitude angles are 30.67°N and 30.98°E, respectively). The obtained results showed that using perforated polyethylene duct increases the indoor air temperature throughout the bird's life, resulting in saved gas consumption by 32.6%, reduced litter moisture content from 41.5 to 32.8 %, reduced supplementary heatfrom 45.72 to 32.4 kWh and increased feed conversion efficiency from 60.4 to 62.2 at the end of birds life.
