Effect of floor type on the ammonia and odour emission from veal calves housing

Abstract

In dit rapport worden de resultaten gepresenteerd van metingen die in opdracht van Productschap Vlees en Vee (PVV) en ICE/Beerepoot op twee bedrijven voor vleeskalveren zijn uitgevoerd volgens de case-control benadering om het effect van verschillende roostervloeren op de emissies van ammoniak en geur te bepalen. Ammoniakemissies waren significant lager voor "Groene vlag" met kleppen, en niet significant verschillend voor "Groene vlag" zonder kleppen en voor "EasyFix", ten opzichte van de traditionele houten roostervloer die ook gemeten is op deze bedrijven (control-case benadering).Geuremissies waren niet significant verschillend voor "Groene vlag" met kleppen, "Groene vlag" zonder kleppen en "EasyFix" ten opzichte van de traditionele houten roostervloer die gemeten is op deze bedrijven (control-case benadering). Summary UKThis report presents the results of measurements performed at two animal facilities for veal calves using the control-case approach, to estimate the ammonia and odour emission reduction of a number of floors compared to the traditional wooden slatted floor. These measurements were commissioned by PVV (Productschap Vlees en Vee) and by ICE/Beerepoot. Ammonia emissions from the floor "Groene vlag" with valves were significantly lower, whereas from the floor "Groene vlag" without valves and from the floor "EasyFix" differences were not significant, when compared to the emission from the traditional floor measured simultaneously within the same farm (case-control approach).Odour emissions were not significant different for the floors "Groene vlag" with valves, "Groene vlag" without valves and "EasyFix" when compared to the emission from the traditional floor measured simultaneously within the same farm (case-control approach).This report can be downloaded for free at http://dx

Ammonia and odour emission from a veal calves housing system with V-shaped manure belt and ‘Groene Vlag’ slatted floor

“…Not all agronomic requirements in the case room were recorded (see Table 3) on room level. When necessary average data were calculated based on results from other rooms in the same production cycle that were measured simultaneously and reported in Mosquera et al (2017).…”

“…The calibration line used for the control room is based on measurements of four ventilators used in four different rooms during simultaneous emission measurements reported in Mosquera et al (2017). Figure 6) with an accuracy of respectively ± 1,0 °C en ± 2%.…”

“…Emission measurements reported here were done simultaneously with those reported by Mosquera et al (2017) and share the same reference (control) room. Ammonia emission reduction of the 'Groene Vlag' slatted floor without valves and traditional manure storage reported by Mosquera et al (2017) was 5.5% ± 2.6% (not significantly different from reference) and ammonia emission reduction of the 'Groene Vlag' slatted floor with valves was 22.3% ± 5.5% (significantly different from reference; p=0.03). Odour emission reductions were -11.1% ± 12.5% and 12.5% ± 14.7 for 'Groene Vlag' slatted floor without and with valves respectively (not significantly different from reference).…”

Monitoring van methaan-, ammoniak- en lachgasemissies uit stallen voor rosé vleeskalveren : Praktijkmetingen in de periode oktober 2018-oktober 2020

“…Wat betreft de ammoniakemissie zijn representatieve metingen op stalniveau voor vleeskalveren beperkt beschikbaar. Voor wit-/blankvlees zijn die gerapporteerd door Hol en Groenestein (1997), Ogink en Lens (2001), , Mosquera et al (2017a) en Monteny en van Hoof (2020). Voor rosé kalveren is dat gedaan door .…”
