The results indicated that dietary betaine addition improved the performance of pigs restrictedly fed diets with diluted energy concentration as found by Cromwell et al. (1999). A maximal response to betaine addition was not observed in this trial. However, betaine did not affect carcass composition, unlike the results of Cromwell et al. (1999) which indicated a reduction of back fat with betaine addition. Choline addition had no effect on performance and carcass charateristics. On an equi-molar basis it appears that pigs respond to betaine rather than choline supplementation, although more work is needed to clarify the mode of action.
