Effect of diet supplementation with Ascophyllum nodosum on cow milk composition and microbiota

This study evaluated Ascophyllum nodosum supplementation in dairy cows and its impact on milk quality. It significantly increased iodine content and reduced free amino acids while maintaining a stable free fatty acid profile.
Supplementation also shifted the milk microbiota, reducing spoilage-associated bacteria (e.g., Pseudomonas) and increasing beneficial species like Lactococcus strains, suggesting improved hygiene and transformation quality.
