Tridge summary
The Temperature and Humidity Index (ITH) prepared by the National Agricultural Research Institute (INIA) foresees two days of high temperatures, which can affect cattle and sheep due to "thermal stress", which "produces economic losses in our systems of production. In these conditions, the animals suffer production losses (milk and meat), physiological and metabolic changes that, in extreme cases, can cause their death ”.

In order for the livestock producer to make decisions on a scientific basis, INIA developed a decision-making tool available via the web and more recently through an App for cell phones. This allows for swift forecasting measures, minimizing production and animal welfare problems. LOSSES OF LITERS AND KILOS INIA technicians understand that “although Uruguay is not in an area where heat stress for bovines is sustained and dangerous, research conducted by INIA has shown significant losses due to not having mechanisms of mitigation. In this sense, milk production in high-production cows falls to around 5 kg in freshly calved cows, and 1.9 kg in advanced lactation due to lack of shade mitigation. In this same sense, subsequent production falls 3.2 kg in the first 60 days in cows that did not receive shade mitigation during the dry period. THE SHADOW IMPROVED THE GAIN In beef cattle, in the corral finishing phase, animals with access to shade had an improvement in the average daily ...
