육계의 계사 형태와 시설수준이 사육환경과 생산성에 미치는 영향

Three types of commercial broiler farms were surveyed to evaluate the effects of housing and production systems on environment and performances in broiler production. Environment condition of broiler house was better in windowless type than vinyl house. Ammonia, carbon dioxide and dust in vinyl house was 28ppm, 2,000ppm, 50.5CPM, respectively. Mortality was higher in vinyl house than that of widowless broiler house. Body weights at the age of 39 days were 1,551g, 1,607g and 1,620g of vinly house, open-sided broiler house and windowless broiler house, respectively. The incidence of abnormal carcass from the vinyl house was higher than those of the others.
