Summary or description

Ruminant production in the tropics is based primarily on native and introduced grass (Poaceae) grazing. The effect of the regrowth age and cutting intensity of Brachiaria hybrid cv Cobra grass was evaluated, and the nutritional value when varying the frequency and intensity of 10 and 15 cm of cutting in the dry season. The study period was from January 19 to March 30, 2017. The variables were dry matter yield, morphological composition, raw protein (RP), neutral detergent fiber (NDF), and acid detergent fiber (ADF). The highest yield was obtained after 56 days in the intensity of 15 cm with 2550 kg MS ha¿1; however, the highest volume of leaves was reached at 35 days with 1200 kg MS ha¿1. The maximum content of Cobra grass RP was in the frequency at seven days with 19.3% in the leaf

component, decreasing as the evaluation time went by. The NDF and ADF content increased with the age of the regrowth.
