Abstract

The presente essay was carried Out from January, 79 up to January, 84 at the Posto de Avicultura de Brotas, State of São Paulo, Brazil. The aim to compare the local behaviour of four forage plant mixtures, under three grazing pressures (high, medium and low). The management sistem used was a continuous one with variable stocking rate during the year. Each mixture was composed by three padocks of different sizes carring equal number of heads during a certain time of the year. Data were analised by covariance through regression lines using one replication (one event). It was studied the seasonal variations of the botanical composition and the content of crude protein for each species and mixtures. The association Melinis minutiflora + Stylosanthes guyanensis taken as standard presented 9.32% of CP; 41.59% of CF and 36.16% of in vitro dry matter digestibility and 2.144 kg of DM remained after grazing. The mixture Setaria + Siratro showed lower protein levels while green panic + Centrosema and Digitaria decumbens cv. Transvala + Cajanus cajan presented lower levels of fiber content and lower amount of dry matter after grazing. it was studied, as well, the effect of management sistems on the botanical composition of the pastures.
