Title:
Costs of New Housing Systems for Pigs with Low Ammoina Emission
Author(s): van Brakel, C.E.P., G.B.C. Backus and N. Verdoes
Publication Date: January 1, 1997
Reference: Ammonia and Odour Control from Animal Production Facilities. Proceedings of a Conference held in Vinkeloord, The Netherlands. 6 - 10 October 1997. p.691-697
Country: Netherlands

Summary:

For each production stage at least 6 different techniques or systems are suggested to meet the Green Label standard which are:
for non-lactating sows 2,5 kg NH3/pig-place per year compared to traditional housing where ammonia emissions are evaluated to 4,2 kg NH3/pig-place per year;
for farrowing sows 4,0 kg NH3/pen per year compared to traditional housing where ammonia emissions are evaluated to 8,3 kg NH3/pig-place per year;
for nurseries 0,3 kg NH3/piglet-place per year compared to traditional housing where ammonia emissions are evaluated to 0,6 kg NH3/piglet-place per year;
and finishers 1,5 kg NH3/pig-place per year compared to traditional housing where ammonia emissions are evaluated to 3,0 kg NH3/pig-place per year for fully slatted floor and 2,5 for partly slatted floor.
The cheapest systems suggested are the most cost effective as they also present the lower costs per kg NH3 reduction.
