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 […]

This research aimed at generating and evaluating prediction equations to estimate metabolizable energy values in poultry offal meal. The used information refers to values of apparent and true metabolizable energy corrected for nitrogen balance (AMEn and TMEn) and for chemical composition of poultry offal meal. The literature review only included published papers on poultry offal meal developed in Brazil, and that had AMEn and TMEn values obtained by the total excreta collection method from growing broiler chickens and the chemical […]

With the objective of determine the apparent metabolizable energy (AME), corrected apparent (AMEn), true metabolizable energy (TMEn) and corrected true (TME) values of eight feedstuffs and their respective coefficient of metabolizability, 300 male broiler chickens, Ross, averaging 21 days old, were assigned to eight treatment (feeds) and one reference diet, in three blocks with two replications per block and five birds per experimental unit. The feedstuffs studied were: two sample of wheat grain (WG), two wheat bran (WB), two corn […]

The traditional method of total collection was used to determine the values of apparent metabolizable energy (AME), corrected apparent energy (AMEn), true metabolizable energy (TME) and corrected true energy (TMEn) of eleven feedstuffs and the respective coefficients of metabolizability of GE. The feedstuffs were as follows: three samples of poultry by-product (PBP), three of feather meal (FM), two of meat and bone meal (MBM), two of swine viscera meal (SVM) and one of viscera and feather meal (VFM) of different […]
