Efeito climático sobre a produção de leite de vacas Guzerá criadas em dois ambientes diferentes

Abstract: O objetivo do presente trabalho foi avaliar o efeito climático sobre respostas fisiológicas de vacas zebuínas em fase de lactação criadas em dois ambientes diferentes. Para a presente pesquisa foram avaliadas 20 vacas da raça Guzerá criadas em ambiente com sombreamento e sem sombreamento. Durante o período experimental, foram realizadas medições das variáveis ambientais diariamente: temperatura do ar, umidade relativa do ar e temperatura de globo negro, para calcular os valores de ITGU. Também foram avaliados … Show more

“…In this context, some indices help in determining the resulting influences of these production systems, such as the Temperature and Humidity Index (THI), the Black Globe Temperature and Humidity Index (BGTI), the Benezra Thermal Comfort Index (BTCI), the Environmental Stress Index (ESI), the Temperature Equivalent Index (ETI), and the Iberian Heat Tolerance Index (Iberian HTI), calculated according to meteorological variables and physiological parameters [3][4][5][6][7]. Thus, in livestock, infrared thermography has proven to be a valuable tool for monitoring animal health and well-being, allowing for the detection of thermal anomalies, the identification of injuries, the evaluation of the thermal performance of installations, and support for the early diagnosis of health, thus providing a more efficient and precise approach to the management and care of herds [8][9][10][11].…”

“…Furthermore, different mathematical indices can be used to measure the degree of stress in cattle, such as the Temperature and Humidity Index (THI), the Black Globe and Humidity Index (BGHI) and the Benezra index [36][37][38][39].…”
