1 Diets: CON = commercial chicken diet without red grape pomace; dGP = commercial chicken diet containing 100 g/kg untreated red grape pomace; dPEG = commercial chicken diet containing 100 g/kg red grape pomace pre-treated with polyethylene glycol (50 g/kg); ENZ = commercial chicken diet containing 100 g/kg red grape pomace pre-treated with Viscozyme®-L (1 g/kg); PENZ = commercial chicken diet containing 100 g/kg red grape pomace pre-treated with polyethylene glycol (50 g/kg) and Viscozyme®-L (1 g/kg). 2 Parameters: MCV = mean corpuscular volume; MCH = mean corpuscular haemoglobin; RDW = red cell distribution width; 3 SEM: Standard error of the mean. a,b,c In a row, dietary treatment means with common superscripts do not differ (p > 0.05).
