Resumo: | The objective of this study was to evaluate the effects of two intermittent grazing strategies, with 24 fixed resting days and 95% light interception in Xaraés 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. |

Para a avaliação das características produtivas, estruturais e bromatológicas foi utilizado o delineamento inteiramente casualizado com medidas repetidas no tempo, com quatro ciclos de pastejo e duas estratégias de pastejo. Para o consumo dos animais foi utilizado o delineamento inteiramente casualizado em arranjo fatorial 2 x 3, sendo duas estratégias de pastejo e três dias de ocupação, e para a taxa de lotação utilizou-se o arranjo 2 x 4 (duas estratégias e quatro ciclos de pastejo). Não houve efeito para as variáveis: disponibilidade, estrutura e composição bromatológica da forragem, com exceção para interceptação luminosa e proteína bruta, onde o tratamento com IL obteve maior valor de interceptação luminosa (2,73% superior que o DF) e menor teor de PB (1,08% inferior ao tratamento DF). Para o consumo de matéria seca houve efeito (P<0,05) entre os dias de ocupação, sendo os maiores valores encontrados no primeiro dia (9,84 kg de MS) e os menores no terceiro dia de ocupação (6,21 kg de MS). A taxa de lotação foi 0,76 UA maior para a estratégia de manejo com IL, quando comparada ao tratamento DF. Assim, tendo em vista a praticidade de adoção, boas condições edafoclimáticas, o manejo de pastejo com intensificação dos dias fixos apresenta grande potencialidade para uso de pasto.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisengUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASArchivos de ZootecniaPastejo rotativoPastagens - ManejoForragemGrazing management strategies for Xaraés grass (Brachiaria brizantha cv.
