Thermal comfort indices in individual shelters for dairy calves with different types of roofs
Provedor de dados: 70
Autores: Fonseca,Patrícia C. de F; Almeida,Eduardo A. de; Passini,Roberta.
Among the building materials used in rural facilities, roofs are noteworthy for being largely responsible for thermal comfort, influencing the thermal balance within the shelter. This study aimed to evaluate the influence of roof on the Enthalpy (H), Thermal Load of Radiation (TLR), and Black Globe Temperature and Humidity Index (BGHI) in individual shelters for dairy calves. The design was completely randomized with three treatments: Z - zinc tile, AC - asbestos-cement tile and ACW - asbestos-cement tile painted white on the upper side. The averages were compared by the Scott Knott test at 1% probability. The results showed no statistical difference between treatments (P&lt;0.01) and the external environment for H. For TLR, there was statistical...

Evaluation of covering materials in individual shelters and its effects on physiological responses and performance of dairy calves
Provedor de dados: 70
Autores: Fonseca,Patrícia C. de F; Almeida,Eduardo A. de; Passini,Roberta.
In Tropical regions, the animal performance is often affected by climate conditions. This study aimed to evaluate covering materials in individual shelters, normally used to house dairy calves, and its influence on the calves physiology and performance. The design used was completely randomized, with a 2x3 factorial arrangement to compare the averages of 5% through the Tukey's test, i.e., both genders- and three types of covering in the shelters (Z - zinc; AC - asbestos cement; and WPAC - white-painted asbestos cement). Parameters evaluated included daily weight gain (DWG), dry matter intake (DMI), feed conversion (FC), rectal temperature (RT), and respiratory frequency (RF). Results showed significant differences (P &lt; 0.05) among males (1.04kg/day) and...
