A study led by Novus International, published in the journal Animals, found that nursery pigs raised without antibiotics grew better on diets with higher sulfur amino acid-to-lysine ratios. The optimal ratio in the first 21 days after weaning may be 13-31% above current National Research Council recommendations.
Late-nursery pigs may need about 5% more sulfur amino acids relative to lysine when antibiotics are not used.
If antibiotic-free production becomes more common, feed formulators may need more methionine relative to lysine, which would support methionine demand. The effect on prices is likely modest and depends on how quickly formulations change.
