Dairy production is negatively impacted by heat stress and the most recent reevaluation of heat stress threshold indicates that dairy cows are affected earlier than previously acknowledged. Our latest research on microbial natural solutions show that, when the best herd management practices are respected (housing and nutrition...), the additional help of these nutritional solutions can benefit the dairy producer. They are an integrated part of its heat stress management program and can help limit the impact of heat stress on cows' health and productivity: live yeast S. cerevisiae I-1077 helps to restore and maintain rumen function, improving rumen pH and feed efficiency during stressful conditions. Organic selenium from selenium yeast restores and protects the animal antioxidant status with positive impact on milk hygiene, cow fertility and immunity.
