【 摘 要 】

The animal performance and productivity in mixtures of annual temperate grasses under continuous grazing condition were evaluated. The mixtures MTR - Triticale (X Triticosecale Wittmack) plus ryegrass (Lolium multiflorum Lam.), MOR - Oat (Avena strigosa Schreb) plus ryegrass, MTOR - Triticale plus oat plus ryegrass, were used. The broadcasting sowing was realized at 04/21/95, being fertilized with 200 kg/ha (05-30-15), being the broadcasting fertilization of 175 kg/ha of nitrogen. The beginning of the grazing occurred at 06/10/95, and was extended until 11/14/95. The average daily weight gain was similar among the mixtures, being 693, 685 and 665 g, for MTR, MOR and MTOR, respectively. The average stocking rate was superior in the MTR mixtures in relation to the others, being 1.210, 1.055 and 1.116 kg of LW/ha. The MTR mixture presented the highest live weight gain/ha (650.7 kg/ha), followed by MTOR (592.4 kg/ha) and MOR (568.8 kg/ha). The cost/ha was superior in the MTR (R$ 320,42), followed by MTOR (R$ 316,47) and MOR (R$ 312,69), the net income was also higher for MTR (R$ 167,60), followed by MTOR (R$ 127,83) and MOR (R$ 113,91). The triticale plus ryegrass mixture was the most indicated because presented the higher weight gain per unit of area, resulting in higher economic return.
