ABSTRACT The objective of this study was to determine the energy values and standardized ileal digestibility (SID) of amino acids of corn, corn protein meal (CPM), corn germ (CG), and dried distillers’ grains with solubles (DDGS) in broiler diets. In the first experiment, the apparent metabolizable energy (AME) and nitrogen-corrected apparent metabolizable energy (AMEn) values were determined using the total excreta collection method. A total of 240 14-day-old broiler chicks were randomly distributed in a completely randomized design with five […]

ABSTRACT This study aimed to evaluate the effect of including an emulsifier (soybean lecithin) and two lipid sources (soybean oil and chicken fat) on the performance and intestinal morphology of broiler chickens. A total of 576 one-day-old Cobb® 500 male chicks were housed in a completely randomized design, with treatments divided in a 2 × 2 factorial arrangement (with and without emulsifier and two lipid sources – soybean oil or chicken fat), totaling four treatments with eight replications and 18 […]
