parí¢metros sanguíneos, histologia, vitamina lipossolúvel, peixes nativos, pisciculturaResumo
As vitaminas estão presentes em pequenas quantidades nos alimentos e são essenciais para o equilíbrio orgí¢nico dos peixes. As vitaminas lipossolúveis são armazenadas no fígado, podem apresentar sinais clínicos de hipovitaminose ou hipervitaminose, e que em ambos os casos podem trazer complicações a homeostase animal. O objetivo do presente trabalho foi avaliar a suplementação de vitamina A em dietas para alevinos de pacu (Piaractus mesopotamicus). Foram utilizados 240 alevinos com peso inicial médio de 17,55 ± 3,22, distribuídos aleatoriamente em 20 caixas circulares de 500 L. As dietas foram suplementadas com acetato de retinol (1,000,000 IU of vitamin A g-1), de forma a conter 0, 3.000, 6.000, 9.000 e 12.000 UI de vitamina A/kg de dieta. Foi observado efeito quadrático sobre os parí¢metros de ganho de peso e conversão alimentar aparente com níveis ótimos de 6.583 e 5.555 UI de vitamina A kg-1 de ração, respectivamente. Não foram observadas influencias da suplementação de vitamina A sobre sobrevivência, composição da carcaça, hematologia e histologia do fígado do pacu. Para obtenção de melhores resultados de ganho de peso e conversão alimentar indica-se a suplementação mínima de 5,555 UI de vitamina A kg-1 de ração para o pacu.
