<i>In vitro</i> characterization of amino acid digestibility and fermentative properties of a specific hydrolyzed yeast, and its <i>in vivo</i> effects on growth performance and fecal microbiota in weanling piglets.

ABSTRACT: Weaning is a stressful event that is often accompanied by anorexia, risk of diarrhea, and development of intestinal disorders, making it crucial to provide highly digestible and palatable diets. Novel functional protein sources are being developed to be included in diets fed to weanling pigs. We evaluated in vitro and in vivo the properties of a recently developed hydrolyzed yeast protein source (Yela ProSecure; YPS; Lallemand SAS, Blagnac, France). The objectives were (1) to evaluate in vitro amino acids (AA) digestibility; (2) to assess, in vitro, the impact of the product's insoluble fraction (YPSi) on the fermentative activity of piglet fecal microbiota; and (3) to test the effects of two inclusion levels (2.5 and 6%) on growth performance and fecal microbio
