Abstract

The research was carried out at the Estação Experimental de Zootecnia de Colina, State of São Paulo. The objective was to evaluate animal performance on colonião grass pastures fertilized with 75kg N/ha/year and of colonião-perennial soybean cv. Tinaroo pastures. Both types of pastures were associated with additional areas of tropical legumes, considered as protein bank, to be grazed during the €œdry season€™. The 52ha experimental area was divided in 20 paddocks of 2ha each and 20 additional areas of 0.6ha per paddock established with 5 different legumes: guandu, leucaena, kudzu, mucuna and yarana as protein bank. Pastures were continously grazed and the stocking rate was reduced in the begining of the €˜dry season€. From June to October the animals had free access to the protein bank areas. The results showed that: 1- the three year average daily liveweight gains were 461 g/head for colonião grass alone and 459g/head for colonião grass plus perennial soybean pastures; 2- the average daily liveweight gains were 518,479,446,427 and 432g/head, respectively for leucaena, guandu, kudzu, mucuna and yarana protein bank throughout the three experimental periods.
