Nitrogen-corrected apparent metabolizable energy values of barley varies by treatment and species.
The aim of this study was to evaluate the effects of two species of poultry (cockerel and Japanese quail), two levels of enzyme (0 and 0.5 g/kg), and 6 processing methods (control (C), gamma irradiation 25 (GI25), and 50 kGy (GI50), autoclaving (AU), fermentation without lactobacillus (F), and fermentation with lactobacillus (FL)) on the nitrogen-corrected apparent metabolizable energy (AMEn) of barley. In this experiment, each processing method was tested at two levels of enzyme (0 and 0.5 g/kg) in six replications with two cockerels or four quails per replication. The results showed that the AMEn values by barley processing methods were: C-11.45 and 12.27; GI25-11.50 and 11.30; GI50-11.49 and 11.29; AU-11.70 and 11.46; F-12.90 and 12.30; FL-1295 and 12.51 MJ/kg in cockerels and quails, respectively. The AMEn (11.49 MJ/kg) of enzyme 0 was significantly lower than that of enzyme 0.5 (12.35 MJ/kg). There was a significant difference in the AMEn of processed barley between cockerels and quails. In conclusion, the most effective processing method of barley for AMEn is fermentation with lactobacillus and enzyme.
