Sensitivity of Dairy Buffalo to Temperature-Humidity Index: Preliminary Study

Abstract

The study highlights the significant impact of temperature and humidity on milk production and the reproductive aspects of buffalo in Italy. Meteorological data were obtained from a meteorological archive, while production and re-production data were obtained from the archive of the Italian Breeders Association. Northern, central and southern Italy comprised the three regions in the study. Production and reproductive parameters were considered for this analysis. Data analysis revealed that THI had a significant impact on production and reproduction parameters. The results indicated that higher THI values were associated with lower milk production, higher fat and protein content and shorter lactation period. Additionally, a longer conception interval was observed in buffalo exposed to higher THI levels. Overall, the dataset provided valuable information on the influence of environmental factors on buffalo performance. These results could influence future management practices to mitigate the negative effects of thermal stress on milk production and reproduction.
