The main effect of probiotic and enzyme supplementation on the kinetics of apparent digestibility coefficient (ADC) in Nile tilapia GIT. The ADC values represent the cumulative ADC from stomach to faeces passing through the proximal, middle and distal gut. The ADC of: crude protein (CP) (panel a,b); phosphorus (P) (panel c,d); calcium (Ca) (panel e,f); and magnesium (Mg) (panel g,h). In panel a, c, e and g (left side) the main effect of dietary probiotics mixture supplementation on ADC values is shown and in panel b, d, f and h (right side) the main effect of dietary enzyme supplementation on ADC values is shown. The ADC in the stomach, proximal, middle and distal were determined on collected digesta in current study. The faecal ADCs were determined on faeces collected by settling columns during the growth trail (published in⁵⁷). Error bars indicate standard error of means. CON-PRO, probiotics added; ENZ-CON, enzymes added; ENZ-PRO, enzymes and probiotics added. Symbols: ns, not significant, #P < 0.1, *P < 0.05, **P < 0.01; *** P < 0.001.
