Reducing ammonia emissions from pig buildings - AW0131

Description
The MAFF Environment group have recently commissioned a research project with ADAS Terrington to identify the differences in levels of ammonia emmission which exist between current UK slurry-based housing systems and the potential to reduce these emissions through adaptations to the floor design (WA0720). The project will compare ammonia emissions from five different fully-slatted or part-slatted floor systems in a controlled replicated study.

This proposal aims to utilise this same project to study the effects of ammonia and flooring systems on the health and welfare of the pigs. It has been proposed in the Council of Europe that part-slatted, as opposed to fully-slatted systems, should be adopted throught the Union to reduce teh global emission of ammonia. However, there is the possibility that this change in flooring system could have a negative effect on the health and welfare of growing/finishing pigs in the UK due to the difference in ventilation systems that are used. The results of this proposed research will enable MAFF to enter into informed discussions concerning the relative merits of different slurry-based housing systems in terms of the health and welfare of pigs.
Objective
01: To determine the effects of ammonia concentration and floor design on the behaviour and consequent welfare of growing/finishing pigs.
02: To determine the effects of ammonia concentration and floor design on the health of growing/finishing pigs as measured by physical performance and level and incidence of respiratory disease.
03: To determine the effects of ammonia concentration and floor design on the health of growing/ finishing pigs as measured by the level of enteric disease.
