Extract

In the Netherlands ammonia emission should be reduced considerably to prevent detrimental effects on the environment. Ammonia is mainly formed by enzymatic conversion of urea and other N-compounds in urine. In traditional fattening pig houses approximately 13% of the N taken in by the feed is emitted as ammonia. Different nutritional factors are influencing ammonia emission. Of these the protein content, the acid-base balance and the carbohydrate composition are the most important. In different experiments the sole effects of these factors on ammonia emission have been investigated. The objective of this study was to determine whether the effects of these factors are additive.
