The Emission Factors Determination at Different Breeding Technology of Laying Hens

Abstract

The study deals with emission factor determination at diff erent breeding technology of lying hens. Concentration of ammonia and greenhouse gases were investigated under the laboratory condition for hens breeding of enriched cages, in comparison with conventional breeding technology with exhaust air cross fl ow (1), technology for layered straw on to dropping belt (2) and technology with exhaust air under the cage's grate (3).
