| Summary: | Managing cattle sheds during the hot and humid summer months in the middle and lower reaches of the Yangtze River poses significant challenges. Ventilation is a commonly used cooling method in cattle farming, yet. Its effectiveness under this region's unique climatic conditions has not been fully explored. This study established a relationship among external conditions, shed microclimate, and cattle through a comprehensive heat transfer model of thermal balance. After verifying the model's accuracy, this study further predicted and evaluated the effects of ventilation and cooling strategies on shed thermal environments and the body heat balance of beef cattle in the region. The results indicated that under hot and humid climatic conditions, ventilation and cooling strategies had a limited impact on improving the thermal environment within sheds. However, with increased wind speed, ventilation significantly reduced cattle respiratory rates, as well as rectal and skin temperatures. It also significantly enhanced convective and evaporative heat loss, ultimately significantly improving latent heat loss efficiency. Increasing wind speeds was found to be more effective in alleviating cattle heat stress in the middle and lower reaches of the Yangtze River. |
