Study links heat stress to increased environmental impact of milk production and highlights nutrition as a key mitigation lever.

Heat stress has a considerable impact on dairy performance and animal welfare. Reduced feed intake and rumination impair milk yield, efficiency, health, and fertility, while increasing environmental impact and economic losses. New data show that rumen‑specific live yeast, by improving rumen function, can support cow performance and welfare and help reduce milk’s environmental footprint under heat stress.
