Onderzoek naar de ammoniak- en geuremissie van stallen LIX : welzijnsvriendelijk huisvestingssysteem voor dragende zeugen in kleine groepen
Ammonia emission from animal husbandry has to be reduced in the Netherlands by 70% in the year 2005, compared with the emission level in 1980. Moreover, new odour legislation requires measurements of the odour emissions of the main conventional and newly developed housing systems. Research was carried out into the emission of ammonia and odour from a naturally ventilated and animal friendly house for pregnant sows. The reducing principle of this house was based on separation of the dunging area by providing a comfortable and spacious lying area with straw bedding. The pens housed 8 sows and provided individual feeding boxes for each of them. The research was carried out during a summer and winter period. The emission of ammonia from the house amounted to 6.3 (summer period) and to 5.5 (winter period) kg/year per animal with 5% correction for under-occupation. The odour emission was 26.1 OUE /s per animal.
