Proteomic Identification and Quantification of Basal Endogenous Proteins in the ileal Digesta of Growing Pigs

Variations in the estimation of basal endogenous losses (BEL) of amino acids in the ileum, as determined by different methods could affect the accuracy of estimating the nutritional value of dietary ingridients. This study used a quantitative proteomic approach to identify variations in BEL in the ileal digesta of growing pigs fed a nitrogen free diet (NFD) or a casein diet (CAS)
