La litt\u00e9rature a d\u00e9montr\u00e9 que la s\u00e9paration de l’urine et des f\u00e8ces sous les lattes et le retrait
\nfr\u00e9quent des deux fractions restreint les \u00e9missions de gaz et d’odeurs provenant du
\nb\u00e2timent, et ce, jusqu’\u00e0 50%. Le principal objectif \u00e9tait de comparer, dans un m\u00eame
\nmontage exp\u00e9rimental, diff\u00e9rents syst\u00e8mes de gestion des d\u00e9jections sur divers aspects
\nrelatifs \u00e0 la qualit\u00e9 de l\u2019air. Pour ce faire, le dispositif exp\u00e9rimental comprenait 5
\ntraitements, dont 3 syst\u00e8mes de s\u00e9paration distincts (gratte en \u00ab V \u00bb, filet, courroie). La
\nfr\u00e9quence de grattage et l’efficacit\u00e9 du proc\u00e9d\u00e9 de s\u00e9paration ont \u00e9t\u00e9 \u00e9tudi\u00e9es.
\nL’exp\u00e9rimentation s\u2019est d\u00e9roul\u00e9e dans 12 chambres identiques, compl\u00e8tement
\nind\u00e9pendantes et ayant chacune leur propre syst\u00e8me de gestion des d\u00e9jections. Chacune des
\nchambres accueillait quatre porcs \u00e9lev\u00e9s de 30 \u00e0 80 kg, et ce, sur une p\u00e9riode de huit
\nsemaines par \u00e9levage. Les r\u00e9sultats ont d\u00e9montr\u00e9 qu’il y a un effet significatif du traitement
\nsur les \u00e9missions d\u2019ammoniac (p=0,02). Sans le proc\u00e9d\u00e9 de s\u00e9paration, le retrait des
\nd\u00e9jections \u00e0 tous les 2-3 jours a r\u00e9duit de mani\u00e8re significative les \u00e9missions d\u2019ammoniac
\nde 46% (52,7 mg jour-1 kgporc
\n-1). Au cours d’une p\u00e9riode d\u2019entreposage de 2-3 jours, la
\ns\u00e9paration de l’urine et des f\u00e8ces directement sous des lattes a permis une r\u00e9duction
\nsignificative de 49% (50,0 mg jour-1 kgporc
\n-1) des \u00e9missions d\u2019ammoniac. Les diff\u00e9rents
\nsyst\u00e8mes de s\u00e9paration ont eu la m\u00eame capacit\u00e9 de r\u00e9duction d\u2019ammoniac. Les r\u00e9sultats
\nont r\u00e9v\u00e9l\u00e9 qu\u2019au cours d\u2019une semaine, il n’y a eu aucun avantage significatif \u00e0 augmenter la
\nfr\u00e9quence de vidange ou \u00e0 proc\u00e9der \u00e0 la s\u00e9paration solide-liquide pour r\u00e9duire les \u00e9missions
\nde gaz carbonique, de m\u00e9thane et d\u2019odeurs. Les diff\u00e9rents syst\u00e8mes de gestion des
\nd\u00e9jections n’ont pas eu d\u2019impact sur le caract\u00e8re h\u00e9donique.<\/p>\n","protected":false},"excerpt":{"rendered":"
