| We evaluated the inclusion of peeled-mango waste meal as a source of carbohydrate in the protein:carbohydrate ratio (CP:CH) on performance and chemical composition of pacamã (Lophiosilurus alexandri) juveniles. One hundred and fifty fish (11.31±0.96g) were stocked in sixteen 500 L tanks, fed three times daily (10% of live weight), in a system with water recirculation with biofilter. The treatments consisted of four experimental diets with decreasing levels of the ratio between crude protein and carbohydrate (1.40, 0.94, 0.56 and 0.29), with four replications per treatment. At the end of 60 days, we evaluated animal performance (final average weight gain, specific growth rate, total apparent feed intake, carcass yield, survival) and physicochemical... |

| ABSTRACT The objective of this study was to evaluate the performance, carcass characteristics and ingestive behavior of feedlot steers fed with three maize hybrids: Maximus VIP3, Defender VIP and Feroz VIP. The experiment lasted 112 days, weighing animals four times, every 28 days. The experimental diets were formulated and constituted by maize silage and pelletized ration in a 50:50 ratio (dry basis). Regardless of the hybrid used, there was an increase in the intake of dry matter with the advance in feedlot evaluation period (9.15, 9.14, 9.35 and 9.59kg day-1, in the first, second, third and fourth weighing, respectively). The type of maize hybrid silage influenced weight gain of animals differently, with a final mean of 1.413kg for animals fed with... |

| Objetivou-se neste estudo verificar o melhor nível de inclusão entre proteína e carboidrato no desempenho e algumas respostas metabólicas em juvenis de pacamã (Lophiosilurus alexandri). Testaram-se quatro dietas com as relações proteína/carboidrato (PB:CHO) 1,24; 0,84; 0,51 e 0,33 durante 60 dias. Foram utilizados 240 juvenis de pacamã pesando inicialmente 1,90g, alimentados duas vezes ao dia (8% da biomassa). Avaliou-se o ganho de peso total, taxa de crescimento específico, consumo de ração aparente, conversão alimentar aparente, rendimento de carcaça e gordura visceral. Glicemia, aminoácidos totais livres no plasma e glicogênio hepático também foram avaliados. A relação PB:CHO influenciou (P<0,05) os parâmetros de desempenho e metabolismo, exceto o... |
