Tratamento biológico do bagaço de maçã e adição em dietas para alevinos

Resumo

The biological treatment of the apple pomace by Gongronella butleri in solid state fermentation and the addition of this material in fish feeding (Nile tilapia) was the fundamental part of this study. The source of nitrogen, initial moisture and granulometry in the biological treatment were appraised. The best conditions being obtained with urea, initial moisture of 70% and granulometry from 0.85 to 1.68 mm, producing 19.63% of soluble protein. The fish submitted to the diet containing treated apple pomace (30% wb) presented an increase of 44% in the corporal mass presenting significant differences at the level of 0.05.
