Abstract

This experiment was conducted at Pirajuí-SP, with the objective of using food reserve areas with sugarcane alone or mixed with tropical legumes (Macrotyloma axilare Verdc. cv. Guata and Galactia striata Urb. cv. Yarana). The strategy had the purpose of supplying addicional source of forages during the dry season, after July, for pastures of Brachiaria humidicola (Rendle) Schweickt. Pastures were grazed with variable stocking rate throughout the year according to the forage available. Maximum animal production when Brachiaria humidicola was grazed solely was 83lg/ha/day at 1.7 AU/ha. During the dry season both treatments had a daily liveweight gain linearly proportional (P < 0.01) to the size of the reserve area. The mixed sugar cane area was superior to the sole sugar cane area (P < 0.01) having an interaction between them and the size of the reserve areas (P < 0.05). Reserve area with sugar cane alone can only be used as suplementary area, while those with sugar cane plus tropical legumes can substitute for around 13% of Brachiaria area with the advantage that during the dry season it gives daily liveweight gains to finish the animals in the pastures.
