Context For sheep production systems, pasture plays important roles: - Lower feed costs Increased sustainability Objectives of the study: Comparison between two housing managements during winter, barn housing vs. pasturing. -Low stocking-densities -Expression of normal behaviour A good social image: Extension of pasturing periods in winter Impacts on sheep welfare Variation in nutrition Harsh and varied climate

Animals 1370 Non lactating Ewes: Observations In barn and … at pasture Plan of the survey 46 farms: - 26 farms in barn - 20 farms at pasture Normal pedoclimatic conditions: 4 6 3 1 1 1 1 2 3 2 4 3 5 1 3 3 2 Barn Pasture Survey’s period February and March 2015

In the context of our study, with pedoclimatic conditions not extreme, and with non-lactating ewes: PrincipleWhat about pasture compared to barn? Good feeding BCS: -No difference for low needs ewes -Risk for young ewes =-=- Good housing Good health Appropriate behaviour Conclusions: What about winter pasturing?

In the context of our study, with pedoclimatic conditions not extreme, and with non-lactating ewes: PrincipleWhat about pasture compared to barn? Good feeding BCS: -No difference for low needs ewes -Risk for young ewes =-=- Good housing Good health - No difference between systems - More frequent concerns in both systems: lameness and dirtiness of the rear end ==== Appropriate behaviour Conclusions: What about winter pasturing?

Good feeding BCS: -No difference for low needs ewes -Risk for young ewes =-=- Good housing Good health - No difference between systems - More frequent concerns in both systems: lameness and dirtiness of the rear end ==== Appropriate behaviour - No difference in response to handling in a race - Ewes appear more confident at pasture = ++ Conclusions: What about winter pasturing?

In the context of our study, with pedoclimatic conditions not extreme, and with non-lactating ewes: PrincipleWhat about pasture compared to barn? Good feeding BCS: -No difference for low needs ewes -Risk for young ewes =-=- Good housing Cleanliness of fleece (flanks): -No problem at pasture++ Good health - No difference between systems - More frequent concerns in both systems: lameness and dirtiness of the rear end ==== Appropriate behaviour - No difference in response to handling in a race - Ewes appear more confident at pasture = ++ Conclusions: What about winter pasturing?
13
From this preliminary study we got promising results for sustainable sheep production Need for larger survey considering: – Different types of animal : breed, physiological states – Including extreme conditions – Stockmanship – Impact on environment Conclusions: What about winter pasturing?
