Growth Performance, Meat Quality, Welfare and Behavior Indicators of Broilers Fed Diets Supplemented with Yarrowia lipolytica Yeast

This study investigated the dietary impact of dried Yarrowia lipolytica yeast (YLP) on growth performance, meat quality, welfare and behavior indicators broilers. It was performed in a commercial poultry farm using 108 13 day-old Ross 308 male The chicks were randomly equally divided into three groups CON, YLP3 YLP5, according to incorporation rate YLP feed (0%, 3%, 5%, respectively). A positive effect foot pad dermatitis (FPD) YLP-fed broilers observed without any adverse effects welfare, behavior, quality overall performance significantly decreased malondialdehyde (MDA) values breast thigh meat. birds presented superior nutrient meat, as indicated by increased concentration monounsaturated fatty acids (MUFAs) polyunsaturated (PUFAs), levels saturated (SFAs), better PUFA/SFA ratio improved health lipid indices. significant elevation n-3 PUFAs groups, compared CON groups. sensory acceptance detected YLP5 group. feeding, at seems be beneficial for improving nutrition quality.
