“…There problems in the agro industrial origin were due to anti-nutrients contents such as lectins, polyphenol, anti-nutritional amino acid, saponins, cyanogen glycoside substances, protease inhibitors, and relatively oxalate (Anwar et al 2016). To reduce anti-nutritional factors there are several technique to increase digestibility using heat, chemicals, machineries, enzyme supplementation, or fermentation (Anwar et al 2016;(Najoan et al 2020a;Tien et al 2014). Compared to Sugiharto et al (2020) protein digestibility did not vary between banana meal treatment and control, this inference noticed better protein digestibility when feeding banana meal to poultry (Sugiharto et al 2020).…”
