Última Latent heat loss of Holstein cows in a tropical environment: a prediction model R. Bras. Zootec. Maia,Alex Sandro Campos; Silva,Roberto Gomes da; Loureiro,Cintia Maria Battiston. Nine lactating Holstein cows with average 526 ± 5 kg of BW, five predominantly black and four predominantly white, bred in a tropical region and managed in open pasture were observed to measure cutaneous and respiratory evaporation rates under different environmental conditions. Cows were separated in three weight class: 1 (<450 kg), 2 (450-500 kg) and 3 (>500 kg). Latent heat loss from cutaneous surface was measured using a ventilated capsule; evaporation in the respiratory system was measured using a facial mask. The results showed that heaviest cows (2 and 3 classes) presented the least evaporation rates. When air temperature increased from 10 to 36ºC the relative humidity decreased from 90 to 30%. In these conditions the heat loss by respiratory... Tipo: Info:eu-repo/semantics/article Palavras-chave: Evaporation rate; Holstein cows; Tropical environment.
