The interrelationships between methionine, choline, and sulfate in turkey diets

Two experiments were conducted with turkey poults to determine the interrelationship of choline, sulfate, and methionine. The addition of choline significantly increased growth and the addition of sulfate resulted in numerically improved growth. However, when the two were added in combination a further improvement in growth was obtained, indicating that both nutrients must be in the feed for maximum utilization of the other. These data also indicate that a complete understanding of the interrelationships between methionine-choline and methionine-sulfate cannot be accomplished unless all three are studied simultaneously.
