|Abstract:||A series of experiments were conducted to determine the apparent metabolisable energy (AME) values of 11 sorghum and 11 barley samples using broilers and layers. In addition the AME values of three selected samples were compared using layer hens and adult cockerels. The mean AME value (MJ/kg DM) of sorghum was 15.0 (range: 14.9 to 15.2) in broilers and 15.1 (range: 14.8 to 15.5) in layers, and the mean AME of barley was 12.5 (range: 11.6 to 13.8)in broilers and 13.0 (range: 12.5 to 13.5) in layers. Digesta viscosities (mPa.s) in birds fed sorghum diets averaged between 2.7 and 2.6 in broilers and layers respectively, with little variation between samples. Digesta viscosities in birds fed barley diets differed widely (P<0.01) between samples with the mean in broilers being 25.5 (range: 8.4 to 70.7) and in layers 11.8 (range: 3.4 to 20.5) mPa.s. Dietary ME values obtained using broilers and layers were highly correlated (Rsq=0.947). In addition, in two of the three samples examined AME values determined with adult cockerels and hens were similar.|
