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 […]

Chemical and amino acid composition and true digestibility coefficients of amino acids of feather and blood meals for birds from different suppliers were determined. Thirty cecectomized cocks were distributed in a completely randomized design, with 4 different feather and blood meals (meals 1, 2, 3 and 4) and one treatment in which the birds remained fasting, with six replications as the experimental unit composed of one rooster. The variations in the chemical composition of the feather and blood meals can […]

Chemical composition, energy values, digestibility coefficients and the values of true amino acid of by-products from slaughterhouses were determined by using the method of “forced feeding” with cecectomized roosters. It was used a complete random design, with two types of fish meal (FM1 and FM2), two types of meat and bone meal (MBM1 and MBM2) and one fasting diet, using six replications with one rooster per experimental unit. The values for apparent metabolizable energy (AME), nitrogen corrected AME (AMEn), true […]
