The study was carried out to observe the fluctuation of milk yield of crossbred cows in two rotational grazing systems of elephant grass cv. Guaçu (Pennisetum purpureum Schum and Tanzaniagrass (Panicum maximum Jacq.), according of period of occupation (2 days of occupation with 40 days resting and 3 days of occupation with 33 days resting, respectively), fertilized with 200 kg of N/ha/year. Nineteen paddocks of elephantgrass and 15 of Tanzaniagrass were studied. The statistical analysis was performed considering lactation phase […]

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 […]

The objective of this experiment was to evaluate the forage potential of new selected clones of elephantgrass. The evaluation was conducted at the Dairy Cattle Research Centre – EMBRAPA, Coronel Pacheco, Minas Gerais, for two consecutive years. Twenty selected clones obtained by the elephantgrass breeding program were evaluated, and two traditional cultivars Cameroon and Taiwan A -146 were used as control. The experimental procedure was a randomized block design with four replicates. The fertilization for both establishment and maintenance was […]
