Sažetak
Intensive pig breeding facilities are associated with high levels of air pollutants that may have adverse effects on both animal and human health. Hygienic standards of air quality in pig housing are determined by physicochemical microclimate parameters and air microorganism content. The emission of ammonia and malodor from stock breeding facilities that exert unfavorable effects both within and beyond the facilities are generated during the process of manure degradation and animal metabolism. Additives are defined as agents added to feed or manure in order to reduce the emission of ammonia and malodor, and characterized by specific properties to improve both microclimate and liquid manure quality. The effect of a commercial food additive based on the Yucca schidigera palm extract in reducing air pollutants in pig fattening units was investigated.The addition of Dc Odorase to animal feed resulted in about 30% reduction in the ammonia and carbon dioxide concentrations and air microorganism count in the pig fattening unit. Standards for assessment and evaluation of additive efficiency including environmental requirements should be adopted in the near future.
