Additional isoleucine without valine in an imbalanced branched-chain amino acid diet further exacerbates its negative effects in broilers
High leucine levels and an imbalanced branched-chain amino acid (BCAA) ratio in the diet can trigger BCAA antagonism, negatively affecting chicken growth. The current study investigated how additional valine and isoleucine could mitigate the negative effects of imbalanced BCAA diets in broilers.
