Fermentation of grain in the rumen and the digestion of starch in the small intestine are influenced by both animal and grain characteristics. Two assays were established to determine the importance of grain characteristics on fermentation and enzyme digestion. To simulate microbial fermentation in the rumen finely milled samples of grain were incubated in rumen fluid and the end products of fermentation and starch disappearance were measured. The second assay was based on amylase and amyloglucosidase and was established to simulate starch digestion in the small intestine. The assays identified large differences between and within grains with respect to both susceptibility of grain to microbial fermentation and enzyme digestibility of starch. Ranking grains on the basis of total acid production identified expected differences between g...

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...
