“…Based on the results of the present study and on studies that analyzed supplementation of the grass carp diet with different protein sources and silages (Camargo et al, 2006;Costa et al, 2008;Nascimento et al, 2018;Sponchiado et al, 2018), we recommend including grass forage in IMTAs with grass carp. Feed supplementation with tifton grass silage for grass carp fed with extruded feed (30% CP) improved weight gain (23.1 g in 45 days) and apparent feed conversion (1.45) of this species (Nascimento et al, 2018). However, this management should be recommended with caution, because, when fed exclusively with forage, grass carp presented problems on nutrition and high mortality (Camargo et al, 2006;Satiro et al, 2021).…”
