Poultry litter has a great diversity of nutrients and can improve the productivity of pasture grasses, providing greater acceptability to animals. The objective of this study was to evaluate the productivity and acceptability by cattle in plots fertilized with chicken litter to replace inorganic fertilizer grazing Pennisetum purpureum cv. Napier. Three grazing cycles were performed (in cycles of grass, every 42 days) with crossbred Nellore animals (380 kg liveweight). The area was divided into five blocks with three plots of 6x7 meters, bounded externally to free access of the animals. On the three grazings, first three hours were evaluated to quantify the acceptability of the animals to the plots. The treatments were: T1 - poultry litter at a dosage of 20 t/ha in one application; T2 - poultry litter at a dosage of 20 t/ha, divided into 5 applications; T3 - urea dosage of 70 kg of nitrogen per hectare per cycle in randomized block design. Yields of dry matter were different in relation to the cycles, not being different between treatments. The concentration of dead material was higher in the second cut, to T1. There was greater acceptance for T1 and T2 treatments. It can be inferred that fertilization with chicken litter to replace inorganic fertilizer, can be used because it maintain productivity of matter and besides providing excellent acceptance of fodder for animals.
