【 摘 要 】

The production and quality of forage of annual temperate grasses mixtures under continuous grazing condition were evaluated. The mixtures used were: T1 - Triticale (X Triticosecale) plus ryegrass, T2 - Oat (Avena strigosa) plus ryegrass, and T3 - Triticale plus oat plus ryegrass. Broadrast sowing occurred at 04/21/95, being the area fertilized with 200 kg/ha (05-30-15). The broadcast fertilization was of 175 kg/ha of nitrogen in urea form and it was subdivided in four applications. The establishment of the pasture occurred from 04/21 to 06/08/95 and grazing period was extended in to 11/14/95. The component triticale and oat presented higher contribution in the initial evaluation of the botanical composition of the residue and the ryegrass in the final evaluations. The accumulation rate was 50.8, 55.6, and 42.1 kg DM/ha•day; crude protein content, 17.7, 18.1, and 16.2%, in vitro organic matter disappearance, 56.4, 56.7, and 57.5%, the % DM of the residue, 23.0, 21.2, and 23.2; and total forage production, 9,696, 10,273, and 8,041 kg DM/ha for T1, T2 and T3, respectively. The mixture of triticale plus ryegrass showed better distribution of production and higher stability in quality during the grazing period.
