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.

Visible Volume: a Robust Measure for Protein Structure Characterization [PDF]

, 1997
We propose a new characterization of protein structure based on the natural tetrahedral geometry of the β carbon and a new geometric measure of structural similarity, called visible volume.
