Abstract | The combined effects of a number of housing related parameters were evaluated in relation to the production efficiency of pigs under commercial farm conditions. These parameters included, air temperature, stocking rate, stocking density and the concentrations of different airborne pollutants. The commercial piggery buildings were divided into two separate compartments containing control and experimental groups of animals. The compartments containing the experimental groups were managed in order to reduce the airborne pollution load on the animals, while the other sections were managed according to normal farm procedures (control groups). The growth rate and environmental variables of both groups were monitored and compared. The statistical analysis (using general linear models) identified key factors contributing to improved production efficiency, including ammonia concentrations in the compartments, the quantity and size of airborne particles and stocking density. This efficiency improvement was achieved without the opportunity to see any perceivable change in clinical health of the animals. Thus improving housing conditions on farms may improve profitability even in cases where livestock are not affected by well-defined infectious diseases. |
