Maize gluten meal protein was used to replace 25, 50, 75 and 100% of the protein supplied by Peruvian fish meal (14.25%) in a cereal‐based diet for caged hens. When the level of maize gluten meal was increased to provide 50% of the supplementary protein, egg production dropped from 80% on the fish meal control diet to 75%, and fell to 53.4% when all the supplementary protein in the diet was provided by maize gluten meal. Mean egg weight dropped significantly when the dietary maize gluten meal supplied 75% and 100% of the supplementary protein. The best food conversion efficiencies were obtained on the two diets with the highest content of Peruvian fish meal. The energetic efficiency for egg production fell slightly when the contribution of dietary protein from the maize gluten was equal to that from the Peruvian fish meal, and fell markedly at the two highest levels of dietary maize gluten meal. The conclusion is reached that satisfactory egg production can be maintained when up to 25% of the protein of the fish meal control diet is replaced by maize gluten meal protein, and that the efficiency of utilisation of energy for egg production is not adversely affected.
