Prediction of metabolizable energy values in poultry offal meal for broiler chickens R. Bras. Zootec.
Silva,Edney Pereira da; Rabello,Carlos Bôa-Viagem; Albino,Luiz Fernando Teixeira; Ludke,Jorge Victor; Lima,Michele Bernardino de; Dutra Junior,Wilson Moreira.
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 composition in crude protein (CP), ether extract (EE), mineral matter (MM), gross energy (GE), calcium (Ca) and phosphorus (P). The general equation obtained to estimate AMEn values of poultry offal meal was: AMEn = -2315.69 +...

Metabolizable energy values of soybean meals and soybean oil for broilers at different ages Animal Sciences
Bertechini, Antônio Gilberto; Kato, Reinaldo Kanji; Freitas, Luís Filipe Villas-Bôas de; Castro, Robert Talles da Costa; Mazzuco, Helenice.
One trial with six analyses of different diets at different ages was carried out to determine the values of apparent (AME), corrected (AMEn), true (TME) and true corrected (TMEn) metabolizable energy of SBM and SBO for broiler chickens from 1 to 42 days of age. Three Brazilian SBM samples and one SBO were evaluated by replacing part of the basal diet with the test ingredient (300 g kg-1 for SBM and 100 g kg-1 for SBO). A total of 1.368 one-day-old male Ross 308 birds were assigned into 36 metabolic cages according to weight in a completely randomized experimental design with six replicates for each test ingredient and basal diet. Six more replicates of fasted birds were used for the determination of metabolic energy and N losses at each age. Four days of...
