The objective of this study was to analyze the effect of whole cassava root scrapings at different levels in diets for broilers in the period of 22 to 42 days of age in high-temperature environments on performance, as well as to evaluate the metabolizability of dry matter (DM), crude protein (CP) and gross energy (GE) and nitrogen balance. A total of 400 male Ross broilers were used for evaluation of performance and 80 birds of the same strain were used in the metabolism experiment. The design was of randomized block with five treatments and four replications. The experimental unit was represented by twenty birds on the performance evaluation and four birds were housed in metabolic cages for the metabolism evaluation. The treatments consisted of diets... |

Foram avaliados o desempenho e a composição muscular da carcaça de alevinos de tambatinga, com peso inicial de 6,521 ± 0,300 g, alimentados com dietas isoenergéticas, isocálcicas e isofosfóricas contendo 40, 37, 34, 31 ou 28% de proteína bruta. Os peixes foram mantidos durante 40 dias em tanques de polietileno, com sistema de recirculação de água. No início e final do experimento, os peixes foram pesados e os dados utilizados para avaliação do ganho de peso diário, consumo diário de ração, conversão alimentar aparente, índice de conversão alimentar, consumo diário de proteína, taxa de crescimento específico e taxa de eficiência proteica. No início e final do experimento, foram selecionadas amostras de peixes para análise da composição muscular, e os... |

Body composition analysis is relevant to characterize the nutritional requirements and finishing phase of fish. The aim of this study was to investigate the relationship between ichthyometric (weight, total and standard length, density and yields), bromatological (fat, protein, ash and water content) and bioelectrical-impedance-analysis (BIA) (resistance, reactance, phase angle and composition indexes) variables in the hybrid tambatinga (Colossoma macropomum × Piaractus brachypomus). In a non-fertilized vivarium, 520 juveniles were housed and fed commercial rations. Then, 136 days after hatching (DAH), 15 fish with an average weight of 37.69 g and average total length of 12.96 cm were randomly chosen, anesthetized (eugenol) and subjected to the first of... |
