Sažetak
A number of biologic preparations added to feed, drinking water or litter are known to improve the housing microclimatic conditions, and consequently the health and productivity of animals. The animal health is specially affected by presence of ammonia, an irritant and poisonous gas in the housing air. Studies have demonstrated a detrimental effect of ammonia on the animal health. Ammonia causes direct irritation to the retinal and respiratory mucosa, resulting in conjuctivitis, respiratory disorders and reduced lung capacity. The possibility of intoxication increases with the duration of stay in the ammonia-satured atmosphere. The maximal allowed concentrations of ammonia vary from 10 ppm (DIN 1810) to the maximum of 50 ppm. In the present review the effect of two commercial food additives based on the sodium alginate obtained from brown seaweed Ascophillum nodosum and on the Yucca schidigera palm extract in reducing air pollutants in pig fattening units were investigated. The addition of Biopolym granulate to the fattening pig feed during three months produced about 50% reduction of the ammonia concentration in the housing air. The addition of De Odorase resulted in 30% reduction of ammonia air concentration. Also, the concentration of other air pollutants was decreased.. In addition, a promising gain increase and mortality decrease were recorded, stimulating further investigations.
