The Pantaneira breed is in danger of extinction. Due to the lack of scientific information on the Pantanal milk potential, this work had the objective of determining the lactation period and a physical-chemical composition of the milk of cows in second order of parturition. The animals were managed in a pasture system rotated in mombaça grass (Panicum maximum) and individually supplemented with concentrate. The milking was performed mechanically twice a day and the milk weighed daily. The physical-chemical characteristics of the milk were evaluated by the ultrasound method and the lactation curves were estimated using the univariate parameter. The average milk yield was 5.34kg/milk/ day and the fat, protein, lactose and total non-fat solids contents were 5.3, 3.7, 6.0 and 10.7%, respectively. Lactation of the cows in second order of calving ended naturally at 180 days and the peak of milk production was reached between 51 and 60 days. Furthermore, there was no difference in milk composition in the different lactation periods.(AU)
