Respiratory rate of ruminants expected to increase by up to 68% due to climate change

Brazilian researchers have developed a methodology that allows them to project how herds of different animal species will respond physiologically to the impacts of climate change between 2050 and 2100. It is estimated that if the average temperature increase of 2 °C is reached by 2050, critical situations for agriculture and the health of animals and humans will occur even more frequently and intensely. Therefore, the results of the research are important for the structuring of public policies, decision-making, and actions by the private sector aimed at avoiding the compromise of production and food security. According to the study, the three scenarios analyzed (2050, 2075, and 2100) will affect small ruminants in the Northern Hemisphere more intensely. The projection is for an average increase of up to 68% in the respiratory rate of these animals compared to those in the South. On the other hand, dairy farming in the South will be the most vulnerable to heat stress among ...
