# New research shows health-challenged pigs perform better with higher lysine to energy ratios

> Research validated that raising the ratio of lysine to metabolizable energy to 110-120% of NRC recommendations improves performance and feed efficiency in pigs facing PRRSV challenges. The study compared two ways of reaching the 120% ratio, either by increasing standardized ileal digestible lysine or by reducing metabolizable energy. The work was based on a 400-pig trial split into vaccinated and unvaccinated barns.

## Why it matters

If producers adopt higher lysine levels in diets for sick pigs, demand for synthetic lysine would rise, supporting prices, though the effect is gradual and limited to disease-challenged herds.
