Digestibility of starch was examined in slow-growing cockerels of laying type (SG) and in fast-growing male chickens (FG) of broiler type fed ad libitum on a maize-type diet until Day 22 of age in one-day periods and from Day 22 to Day 100 in three-day periods. Digestibility was estimated using the chromic oxide indicator method. In SG chicks, starch digestibility rapidly increased within the first days of their lives and reached the value of 0.986 already on Day 4 of life. It was maintained on this level till the end of the experiment, which was finished at the age of 100 days. In FG chicks, which in comparison with SG birds consumed more than a double quantity of feed, high starch digestibility was observed as late as on Day 8. From Day 8 to Day 100 of age, starch digestibility slightly but highly significantly (P < 0.01) decreased. The average value of digestibility was lower by 0.008 in broiler type chickens than in SG chickens at this time; nevertheless, digestibility was never below 0.96. The difference was highly significant (P< 0.001).

Various food by-products were incorporated into rice grits and submitted to extrusion cooking to produce fortified extruded food products. The blends of various formulations of durum clear flour (8—20%), partially defatted hazelnut flour (PDHF) (5—15%), fruit waste blend (3—7%) and rice grits were extruded using single screw extruder. Response surface methodology was used to evaluate the effects of process variables, namely the feed moisture content (12—18%), barrel temperature (150—175 °C) and screw speed (200—280 rpm), and change in feed composition on total phenolic content, antioxidant activity, percent starch gelatinization and starch digestibility of the extrudates. Extrusion cooking process significantly increased the level of phenolic compounds and starch digestibility of extruded products. Increasing PDHF and fruit waste content caused increase in total phenolic content and antioxidant activity of the extruded samples, whereas percent starch gelatinization and digestibility values decreased. Moisture content and temperature significantly influenced the total phenolic content, antioxidant activity, percent starch gelatinization and starch digestibility values. In extruded samples, positive correlations were determined between antioxidant activity and total phenolic matter and percent starch gelatinization and the starch digestibility values, respectively.
