Digestible lysine levels for laying hens and their effects on egg quality

Acta Scientiarum: Animal Sciences, 2014
Egg quality of semi-heavy laying hens fed on low protein diets (14.0% CP) and on different lysine levels is evaluated, while maintaining the same ratio of digestible amino acids / digestible lysine.

Effect of Varying Levels of Dietary Tryptophan on Aggression and Abnormal Behavior in Growing Pigs

Frontiers in Veterinary Science, 2022
Body lesions, resulting from tail-biting and ear-biting, can result in decreased health and welfare in pigs. Tryptophan, an indispensable amino acid, is needed to support protein deposition, and the synthesis of the neurotransmitter serotonin, which is ...

Single-phase feeding and compensatory growth in growing and finishing pigs (OK-Net Ecofeed Practice Abstract) [PDF]

, 2020
• Limit the supply of essential amino acids during early growth and utilise the pigs’ capacity to fully compensate for the restriction by increased protein retention and faster growth during later growth phases.
