In growth and digestibility experiments, rolled barleys of 14·2, 18·0 and 21·5% moisture content (the two latter barleys having had a propionic acid‐based preservative added) were fed to bacon pigs with either the protein, vitamin and mineral supplements mixed to form a complete diet or added to the barley in the feeding trough without mixing. There were no significant differences between these two methods of feeding in terms of digestibility, growth rate and conversion efficiency. The diets based on the 18·0 and 21·5% moisture barleys contained higher percentages of larger sized particles than the other diet, but gave significantly better growth rates and efficiencies of conversion and thicker backfat deposits. The results from the digestibility experiments did not show that these results were necessarily caused by differences in digestibility.
