Summary

O objetivo deste trabalho foi avaliar a digestibilidade aparente de farelos vegetais, submetidos ou não a tratamento químico para extração de antinutrientes, em dietas para jundiá (Rhamdia quelen). Foram formuladas três dietas-teste com fontes proteicas na forma comercial sem tratamento - SNT, farelo de soja; CNT, farelo de canola; e GNT, farelo de girassol - e três dietas submetidas a tratamento para redução de ácido fítico, fenóis totais e taninos totais: ST, farelo de soja tratado; CT, farelo de canola tratado; e GT, farelo de girassol tratado. Os tratamentos CNT, CT, GNT e GT apresentaram menor digestibilidade aparente da matéria seca. O tratamento ST apresentou maior digestibilidade da proteína bruta que CT e CNT, mas não diferiu dos demais tratamentos. Os tratamentos GNT, GT e CNT apresentaram as menores digestibilidades da matéria orgânica. A remoção de antinutrientes não afeta a digestibilidade aparente de proteína bruta, matéria seca e matéria orgânica dos farelos de soja e girassol, mas melhora a digestibilidade da matéria seca do farelo de canola.

Summary translation

The objective of this work was to evaluate the apparent digestibility of plant-protein meals, subjected or not to antinutrient extraction chemical treatment, in diets for South American catfish (Rhamdia quelen). Three test diets were formulated with protein sources in commercial form without treatment - SNT, soybean meal; CNT, canola meal; and GNT, sunflower meal - and three diets were subjected to treatment for reduction of phytic acid, total phenols, and tannins: ST, treated soybean meal; CT, treated canola meal; and GT, treated sunflower meal. The treatments CNT, CT, GNT, and GT had lower dry matter apparent digestibility. The treatment ST had higher crude protein digestibility than CT and CNT, but it did not differ from the other treatments. GNT, GT, and CNT treatments showed the lowest organic matter digestibility. Antinutrient removal does not affect the apparent digestibility of crude protein, dry matter, and organic matter of soybean and sunflower meal, but improves the dry matter digestibility of canola meal
