The effect of supplementing low-forage dairy diets (28% forage) with rumen protected lysine and methionine to balance amino acid levels was evaluated. Supplemental amino acids did not alter milk fat and protein but had beneficial effects on milk yield and mammary health, increasing yields by +0.6 kg/d and decreasing risk of mastitis (0.39 times lower).

Based on 2021 American Dairy Science Association (ADSA) abstract:
P461 Supplementing low-forage diets with rumen-protected Met and Lys results in a reduction in mastitis risk and a modest increase of milk yield for mid-lactation multiparous Holstein cows.
