Abstract
Growth and food conversion efficiency of broilers were reduced at low dietary choline concentrations. These effects were accentuated by low dietary total S amino acids (TSAA). Increased mortality, perosis and other pathological changes involving a number of tissues were observed in birds fed on a low-choline diet. Methionine replaced part of the dietary requirement for choline at low dietary choline concentrations. High dietary concentrations of choline (> 1750 mg/kg) increased the requirement for dietary TSAA. Increasing the dietary choline while maintaining the TSAA at an inadequate level may decrease performance.
