| Abstract: | The objective of this research was to evaluate the thermal efficiency of roofs used on
individual shelters during milk-feeding stage of Girolando calves. The research was conducted at a
farm located in a dry region of Pernambuco state, Brazil. The experimental design was completely
randomized, with 27 Holstein × Gir dairy crossbred calves housed in shelters with three roofing
materials (fibre cement tile, recycled tile, and thatched roofs). The recycled tiles and thatched roofs
provided reductions of 18.7 and 14.6% in radiant thermal load, respectively. Regardless the roofing
material, all animals increased their respiratory rate to maintain thermal equilibrium. |
