Giới thiệu về tác giả
Dr Yves Nys is former Research Director for the Poultry Unit at INRAE, France. As a scientist, he studied calcium metabolism in hens (eggshell quality and fabric), mineral nutrition and egg quality (nutritional value and biological activity of egg proteins). With over 200 publications, Dr Nys is regarded as one of the world’s leading authorities on optimising the nutrition of laying hens. The recipient of a number of awards for his research, he has served as Vice-President of the WPSA, president of the European Federation and has coordinated two major EU research projects on egg quality.
