- Abstract
This study aimed to evaluate the forage yield, chemical composition and dry matter recovery of buffel grass hay (Cenchrus ciliaris L.), at different cutting heights. The experiment was conducted at the Estação Experimental Pendência of Empresa Estadual de Pesquisa Agropecuária da Paraíba S.A (EMEPA), located in city of Soledade-PB. A randomized complete block design was used, with four cutting heights (30; 40; 50 and 60cm) with five replicates. The forage yield had effect with a linear increase in values achieving dry matter yield 7206.78kg/ha for 60cm height. There was harvesting height effect for leaf, stem and leaf:stem ratio in dry matter, wherein the values of leaf:stem ratio decreased with increasing harvesting height, getting values of 0.87 to 0.48 when harvested at 30 and 60cm height, respectively. Quadratic effect was observed in harvesting height only to the neutral detergent fiber, with contents ranging from 71.82 to 77.08% in dry matter. The average values of dry matter of hay were between 82.44 and 84.48%. The dry matter recovery in dehydration decreased in function of harvesting heights, showing linear behavior, with the smallest average observed for the grass to 60cm (76.58%). The absence of variation in the bromatological constituents and dry matter final losses and higher biomass production in the highest cutting harvest may conclude that buffel grass is to be harvested in the cutting height that enable greater production.
