dc.descriptionMilk production in Brazil has been transformed lately due to the new worlds economical order and new technology has been adopted by the producers for improving productivity. To minimize the negative effect of the tropical environment in the dairy cows it is necessary to understand the relationships between the animal exposed to heat stress and its physiological response. This present research was carried out at Animal Science Institute, in São Paulo and had the objective to evaluate three different types of shade for milking cows lodged in open field. The tested treatments were: 1) artificial shade using a propylene screen 80% direct solar radiation reduction; 2) the same shade using a fan of 0.5 HP; and 3) the same shade structure using a fan 0.5 HP with fogging system. Eighteen milking cows were used in the treatments been 12 Holstein cows and 6 Brown Swiss equally distributed in the treatments according to their age and milk production level. The parameters analyzed were: milk production and fat content; body temperature, respiratory frequency, and cardiac frequency. Environmental parameters measured were dry bulb, black globe temperature and relative humidity, collect in each treatment and at a meteorological station at nearby site. The statistical package Software S-Plus 4.5 was used for evaluating the results. The results showed that the best treatment was the shade using forced ventilation associated to fogging system.
