The milk production, the dry matter intake (DMI) and the NDF passage rate in the gastrointestinal tract in four seasons (July, October, January and March), of crossbred cows, under grazing of elephant grass, submitted to two levels of nitrogen (300 and 700 kg N/ha•year) were estimated. The rotation grazing with three days of occupation and 30 days of resting, using 36 crossbred Holstein Zebu milking cows, in a stocking rate of 6 cows/ha, was used. The estimates of the intake […]
