Proximate analytical data and estimated metabolisable energy values (for poultry) for 171 samples of oats and 179 samples of barley for 3 seasons are presented. The results showed that both grains were extremely variable in crude protein content, the barley rather more so than oats. In contrast, both cereals were relatively constant in calculated metabolisable energy values with oats being more variable than barley. Some of the more important implications of these results in practical livestock feeding are discussed. It is concluded that it would be worthwhile for farmers who home‐mix cereals with concentrates to have samples of grain analysed in order to admix concentrates most effectively and economically. Techniques of sampling however, require to be clearly understood for worthwhile results.
