The objective of this trial was to estimate the upper critical levels of the temperature-humidity index (TUI) measuring morning and afternoon rectal temperature (RT), respiratory rate (RF), and hair coat surface temperature (ST) of ½, ¾ and 7/8Holstein-Zebu (HZ) dairy cows during two consecutive years (two summers and two winters) in Coronel Pacheco, MG, Brazil. Correlation and multiple analysis were determined using data obtained from 15 dairy crossbreed cows/season; five from each genetic group (GG). Results showed that RF was […]
