Abstract

Fed intake and milk production of Holstein-Zebu crossbred cows, grazing Napier grass (Pennisetum purpureum) (NAP), Brachiaria decumbens (BRA) and Guinea grass (Pannicum maximum) (COL) and supplemented with four kg of concentrate, were evaluated in a double Latin square (3x3). Fecal production and feed intake were calculated using Cr2O3 and in vitro digestibility. Dry mater intake (DMI) was similar among forages (18kg/cow) which represented 2.72%; 2.84% and 2.96% of the live weight for NAP, BRACH and COL respectively. The intake per unit of metabolic size (g DM/kg0.75) was 130 for NAP, 135 for BRACH and 145 for COL. The intake of BRACH resulted in lower milk production (14,4kg) than NAP (15,5kg) and COL (16,1Kg). Grasses did not affected the milk composition which showed 4,03% of fat, 2,46% of protein and 12,42% of total solids. It was concluded that NAP, BRACH and COL are good alternatives for milk production in grazing systems.
