The experiment was performed to evaluate plasma urea nitrogen (PUN) level of crossbred cows under two rotational grazing areas, one of elephantgrass cv. Guaçu (Pennisetum purpureum Schum. cv. Guaçu) and other one of Tanzaniagrass (Panicum maximum Jacq. cv. Tanzania). Forage production, stem, leaf and dead material were also evaluated, on dry matter basis (DM), as well as the crude protein (CP) and neutral detergent fiber (NDF) in the forage samples. Blood was collected four times, using 16 cows for grass […]
