| ABSTRACT: The cloacal and surface temperatures are important physiological parameters to quantify the thermal comfort of animals, its variations may occur as a function of thermal variables. In this context, the goal of the present study was to evaluate the cloacal (tclo) and surface (tsur) temperatures of Cobb 500® broilers, in the second week of life, subjected to different air dry-bulb temperature (24, 27, 30 and 33 °C) and stress durations (1, 2, 3 and 4 days). The experiment was carried out in four climate-controlled wind tunnels. Air relative humidity and air velocity were set at 60% and 0.2 m s-1, respectively. The tclo and tsur were measured daily through digital thermometer and thermographic camera, respectively. Analysis of variance and Scott... |

| ABSTRACT: The aim of this study was to evaluate the effects of three enteral electrolyte solutions, each with different energy sources, administrated as continuous flow on the physiological parameters and blood count of healthy Holstein heifers. Six Holstein heifers were used in a crossover design. All animals received all three treatments: solution with calcium propionate, 4g of NaCl, 0.5g of KCl, 0.3g of MgCl2, and 10g of calcium propionate diluted in 1000mL of water (measured osmolarity: 299mOsm/L); solution with glycerol, 4g of NaCl, 0.5g of KCl, 0.3g of MgCl2, 1g of calcium acetate, and 10mL of glycerol in 1000mL of water (measured osmolarity: 287mOsm/L); solution with propylene glycol, 4g of NaCl, 0.5g of KCl, 0.3g of MgCl2, 1g of calcium acetate,... |
