Abstract 1. Growth and food conversion efficiency of broilers were reduced at low dietary choline concentrations. These effects were accentuated by low dietary total sulphur amino acids (TSAA). 2. Increased mortality, perosis and other pathological changes involving a number of tissues were observed in birds fed on a low‐choline diet. 3. Methionine replaced part of the dietary requirement for choline at low dietary choline concentrations. 4. High dietary concentrations of choline (> 1 750 mg/kg) increased the requirement for dietary TSAA. 5. Increasing the dietary choline while maintaining the TSAA at an inadequate level may decrease performance.
