To adapt to the heat, cows change their daily behavioral pattern with less lying time, more activity and decreasing distance between animals. To help reduce the impact of heat stress, nutritional tools can helpThe rumen-specific live yeast strain, Saccharomyces cerevisiae CNCM I-1077 (LEVUCELL SC), has been shown to mitigate production declines during periods of heat stress. Reducing heat stress can be accomplished through monitoring, management techniques and nutritional supplements. Global heat stress impact assessmentTo aid in evaluating the impact of heat stress on productivity, THI data are routinely gathered, contributing to a comprehensive global map. This resource is designed to offer insights into the varying degrees of heat stress experienced worldwide and the corresponding production challenges.
