Hazards related to prolonged hunger. Hazards written in bold are scientifically proven by more than one source, those in normal text were found in only one paper, those in italic have been mentioned by the experts invited to the technical hearing meeting

Hazard category	Hazard
Housing	Badly designed or managed (soiled) feeder leading to reduced access or increased competition for feed Poorly designed or managed drinker leading to low water intake
Ambient condition	Low (< 10°C) or high (> 30°) ambient temperature High humidity leading to a poor quality of the feeds
Genetics	High prolificacy lines
Nutrition and feeding	Breakdown of automatic feeding systems Underfeeding due to too high feed restriction Badly formulated feeds, inadequate for nutritional requirements
Management of biosecurity	Unhygienic feed through soiling
Management of reproduction	Intensive reproduction cycle length (35–38 days)
Other	No hazard identified
