Ad libitum feeding systems for lactating sows: effects on productivity and welfare of sows and piglets

Sarah C. Gorr, Christine Leeb, Werner Zollitsch, Christoph Winckler, Thomas D. Parsons

Published in 2024

Scientific article evaluating the effects of three ad libitum feeding systems on the productivity and welfare of suckling sows. Results show that sows fed ad libitum convert feed more efficiently for better piglet growth without additional weight loss. With these systems, sows spend more time feeding, which would meet the pigs' behavioral need to forage.

Welfare issues resulting from feed restriction in pregnant sows

EU Reference Centre for Animal Welfare Pigs (EURCAW-Pigs)

Published in 2024

This article, intended for inspectors in EU Member States, describes the effects of feed restriction on the welfare of pregnant sows. Indicators of hunger-related aggression and stereotypies are described, along with measures to help sows feel satiated by increasing the fibre content of their diet, and to mitigate these behaviors by modifying various aspects of the living environment.

Published in 2022

Scientific review identifying an increased risk to free-range hens of microbial and parasitic infections, heat stress and predation. They do, however, have better bone quality and show less evidence of pecking behaviors. The review sets out existing preventive strategies and identifies missed opportunities to use genetics and prenatal and nutritional factors to prevent these welfare issues in free-range systems.
