This experiment aimed to simulate thermal-stress-environment conditions in climatic chamber during the transportation of birds to slaughterhouse to evaluate the influence of these conditions on physiological parameters and carcass conformation in broiler chickens. Thirty chicks with 42 days old were weighted and distributed to transportation crates (10 chicks by crate), and submitted to high stress conditions (35ºC and 85% RH) to simulate the transport to the slaughterhouse. At each time of exposition to the stress conditions (0, 30, 60, 90 […]

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 […]
