Multivariate analysis of the behavior and physiology of Girolando heifers in pasture

Abstract: The objective of this study was to evaluate the thermal effect on the behavioral and physiological changes of Girolando heifers by means of principal components analysis. The research was conducted in the Agreste region of the state of Pernambuco, Brazil. Three heifers submitted to the continuous grazing system were used. For the determination of the thermal effect on the animals, the variables dry bulb temperature and relative air humidity were recorded, which allowed to determine the temperature and humidity… Show more

“…A ação dos elementos meteorológicos como a temperatura de bulbo seco, umidade relativa, temperatura de ponto de orvalho e temperatura de globo negro podem interferir no comportamento dos animais (Batista et al, 2019). Por isso, alterações nos valores das variáveis meteorológicas podem influenciar no tempo em que os animais despendem para realizar as classes comendo, bebendo e ócio.…”
