Evaluación de dietas isoenergéticas con varios niveles de proteína y de harina de pescado en alevinos de bocachico (Prochilodus magdalenae)

To measure the effect of three protein levels (24, 28 and 32%) with and without the incorporation of fishmeal HP (7.5 and 0%), isoenergy diets (3100 Kcal / kg), with similar amounts of five essential amino acids (lysine, methionine + cystine, threonine and tryptophan) in the performance of bocachico (Prochilodus magdalenae) fries, in an experiment of 32 days was performed. For this purpose a completely randomized design with a factorial arrangement 3 * 2 (three levels of protein and two levels of HP) due to a difference in initial weights and standard lengths was employed. An ANACOVA, to assess the effect of the six diets in the final weight, weight gain expressed as percentage, specific growth rate and gain in standard length was executed. Finally, it was concluded that no significant difference (P> 0.05) among the different diets on these parameters was detected, so it can be stated that bocachico fries well tolerated diets devoid of fish meal as long as they have with a good balance of amino acids; furthermore, they can show also a good performance with diets with protein content of 24%.
