DOI: 10.1038/s41598-024-53039-7
Abstract: We hypothesised that resource choice during early life contributes to both current and longer-term beneficial effects on animal welfare. We investigated this hypothesis in a longitudinal cross-over experiment with laying hen pullets (Gallus gallus domesticus)… read more here.

DOI: 10.1080/00439339.2020.1789023
Abstract: SUMMARY Worldwide, commercial laying hens are frequently being used for only one production cycle mainly due to a decline in egg quality and/or egg quantity at 70–80 weeks of age. Extending the production cycle of… read more here.

DOI: 10.1109/access.2022.3141090
Abstract: The arrangement of temperature sensors in most existing large-scale laying hen houses is random or placed according to the experience of breeders. However, this can’t achieve accurate monitoring of the henhouse. The temperature in the… read more here.
