| Abstract | espanolObjetivou-se com este estudo, avaliar os efeitos de duas estrategias de pastejo intermitente, com 24 dias fixos de descanso e com 95% de interceptacao luminosa em capim-xaraes. Para a avaliacao das caracteristicas produtivas, estruturais e bromatologicas foi utilizado o delineamento inteiramente casualizado com medidas repetidas no tempo, com quatro ciclos de pastejo e duas estrategias de pastejo. Para o consumo dos animais foi utilizado o delineamento inteiramente casualizado em arranjo fatorial 2 x 3, sendo duas estrategias de pastejo e tres dias de ocupacao, e para a taxa de lotacao utilizou-se o arranjo 2 x 4 (duas estrategias e quatro ciclos de pastejo). Nao houve efeito para as variaveis: disponibilidade, estrutura e composicao bromatologica da forragem, com excecao para interceptacao luminosa e proteina bruta, onde o tratamento com IL obteve maior valor de interceptacao luminosa (2,73% superior que o DF) e menor teor de PB (1,08% inferior ao tratamento DF). Para o consumo de materia seca houve efeito (P EnglishThe objective of this study was to evaluate the effects of two intermittent grazing strategies, with 24 fixed resting days and 95% light interception in Xaraes grass. For evaluation of productive, structural and nutritive characteristics, we used a completely randomized design with repeated measures in the time, with four grazing cycles and two grazing strategies. For consumption by the animals, we used a completely randomized design, in a 2 x 3 factorial, with two grazing strategies and three days of occupation. There was no effect for the variables: availability, structure and chemical composition of forage, except for light interception and crude protein, in which treatment with LI showed the highest value of light interception and lower content of CP. There was effect for dry matter intake between the days of occupation, and the highest values found on the first day and the lowest on the third day of occupation. Thus, taking into account practicality of adoption, good soil and climatic conditions, grazing management with intensification of fixed days shows great potential for pasture use. |
