Resumo: | Dietary fatty acids may influence the development of the digestive tract and initial activation of digestive enzymes in fish. The objective of this study was to evaluate the effect of the diet lipid profile on ontogeny and activity of digestive enzymes in silver catfish post larvae fed practical diets. Five diets were tested, replacing broiler liver by soybean protein concentrate (SPC) or fish meal (FM): Standard, 15SPC, 30SPC, 15FM and 30FM. The enzymatic activity of fish was analyzed from 32 Hours after fertilization (Haf). Were analysed acid protease, trypsin, chymotrypsin, lipase, amylase and maltase. The development of the digestive system was analyzed from first feeding up to 28 days by histological techniques. The enzymatic activity presented peaks for the post-larvae fed with the 15SPC diet and fish fed with diet 15FM showed best growth. The development of the digestive system did not suffer damage from the diets offered. Post-larvae fed the 30SPC diet showed reduced development of the digestive tract. The diet 15FM provide good lipid profile for silver catfish post larvae. |

El objetivo de este estudio fue evaluar el efecto del perfil lipídico de la dieta sobre la ontogenia y la actividad de las enzimas digestivas en postlarvas de jundiá alimentadas con dietas prácticas. Se probaron cinco dietas, reemplazando el hígado de ave por concentrado de proteína de soja (CPS) o harina de pescado (FP): control, 15CPS, 30CPS, 15FP y 30FP. La actividad enzimática de los peces se analizó 32 horas después de la fertilización. Se analizaron proteasa, tripsina, quimotripsina, lipasa, amilasa y maltasa. Se analizó el desarrollo histológico desde el inicio de la alimentación hasta los 28 días. La actividad enzimática mostró picos para las postlarvas alimentadas con la dieta 15CPS y los peces alimentados con la dieta 15FP mostraron un mejor crecimiento. El desarrollo del sistema digestivo no sufrió daños por las dietas ofrecidas. Las postlarvas alimentadas con la dieta 30CPS mostraron un desarrollo reducido del tracto digestivo. La dieta 15FP proporciona un buen perfil lipídico para las postlarvas de jundiá.Os ácidos graxos da dieta podem influenciar o desenvolvimento do trato digestório e a ativação inicial das enzimas digestivas em peixes. O objetivo deste estudo foi avaliar o efeito do perfil lipídico da dieta na ontogenia e atividade de enzimas digestivas em pós-larvas de jundiá alimentadas com dietas práticas. Foram testadas cinco dietas, substituindo o fígado de aves por concentrado protéico de soja (CPS) ou farinha de peixe (FP): controle, 15CPS, 30CPS, 15FP e 30FP. A atividade enzimática dos peixes foi analisada a partir de 32 horas após a fertilização. Foram analisadas a protease, tripsina, quimiotripsina, lipase, amilase e maltase. O desenvolvimento histológico foi analisado desde o início da alimentação até 28 dias. A atividade enzimática apresentou picos para as pós-larvas alimentadas com a dieta 15CPS e os peixes alimentados com a dieta 15FP apresentaram melhor crescimento. O desenvolvimento do sistema digestório não sofreu danos das dietas ofertadas. Pós-larvas alimentadas com a dieta 30CPS mostraram redução do desenvolvimento do trato digestório.
