Abstract

The present work was done in the annexes of Zootechny Department Veterinary School of Federal University of Goiás, in Goiânia municipality, from January to September, 1986. The objective was to determine the chemical composition and productivity of Andropogon grass (Andropogon gayabus var, bisquamulatus cv. Planaltina) at different cutting ages (40, 54, 68 and 83 days) after uniformization, aiming hay production. In order to study chemical composition and productivities in dry matter and crude protein before hay making, a randomized blocks design was adopted with 5 replications. Average contents of dry matter, crude protein, crude fiber, calcium and phosphorus were determined, as well as productivities of dry matter and crude protein. The information obtained by the present work permitted to conclude that pastures formed with Andropogon grass present good conditions for haymaking at ages of 54 to 68 days after new sprouting.

KEY-WORDS: Cutting age, chemmical composition; dry matter and crude productivity; hay.
