Abstract

The experiment was carried out at FCAV €“ Campus de Jaboticabal in the period of winter-spring-summer of the 2001-2002 and 2002-2003, to determine the crude protein (CP), cell wall (NDF ADF, lignin) and in vitro organic matter digestibility (IVOMD) of the Tifton 85 pasture overseeded with winter species. The treatments were: bristle oat; yellow oat; triticale; bristle oat + yellow oat; bristle oat + triticale; yellow oat + triticale; bristle oats + yellow oats + triticale, overseeded in the area of the Tifton 85 grass; and, T-85: area only with the grass-Tifton 85. The plants were cut at 20 cm (presence of annual winter grasses) and 10 cm (absence of the annual winter grasses) of the soil level. The protein content was highest in the first year of evaluation compared to the second experimental year. The same behavior was observed, in the two years, on the cell wall content. The NDF content increased, and the ADF and lignin decreased lightly. The IVOMD presented variation in function of the botanical and morphologic composition on the different evaluations in the growth periods.
