This study evaluated the efficacy of the commercial phytogenic product (Herb-All COOL) in alleviating heat stress and improving performance and health in dairy cows in Italy, Egypt, and Mexico. Heat stress was quantified using the temperature-humidity index (THI). In all three countries, cows supplemented with Herb-All COOL showed higher milk yield compared with non-supplemented controls under similar THI conditions. In Italy, Herb-All COOL the daily milk yields was increased up to 4.8 kg/cow/day during the hot summer associated with the reduction in somatic cell count (SCC) across lactation. Similarly, the average milk yield increased by 3.1 kg/cow/day with Herb-All COOL supplementation in Egyptian dairy cows. In Mexico, although the volume of milk production was reduced, however, the decline in milk yield during periods of heat stress was less obvious in the supplemented group. Beside the milk production, various fertility parameters could also be improved, such as higher first-service conception rate, higher overall conception rate, shorter days to confirmed pregnancy, improved estrus expression, and conception rate. Post-parturient need for medication per cow was also reduced, resulting in a marked decrease in the number of culled cows in the Herb-All COOL groups at the end of the season. These findings indicate that Herb-All COOL can mitigate negative effects of heat stress on productivity, fertility, and health in high-producing dairy cows across different climatic zones.
