Abstract

Intensively managed, steep pastures of stargrass outyielded those of guineagrass in terms of milk production when grazed by cows receiving no concentrate feed over a 2-yr period under conditions typical of the humid mountain region of Puerto Rico. Cows on stargrass pastures produced an average of 7,727 1iters of milk/ha/yr and provided 729 cow-days of grazing/ha/yr, whereas cows on guineagrass pastures produced 5,593 liters/ha/yr and provided 543 cow-days of grazing. Daily milk production per cow was similar for cows fed on either grass. Cows on stargrass pastures produced more milk during all seasons of the year than those on guineagrass pastures. In addition, guineagrass pastures exhibited more seasonal variations in productivity.
