Resumo: | This study was designed to evaluate the effects of different supplementation plans on the nutrient intake, apparent total-tract digestibility, grazing behavior, growth performance, and carcass characteristics of beef cattle under grazing conditions from ages 4 to 18 months old. The beef calves grazed Brachiaria decumbens in four seasons: rainy-dry transition, dry, dry-rainy transition, and rainy. Forty-four animals (11 per treatment) were randomly assigned to one of four nutritional plans of supplementation defined by the quantity of supplement offered: control, low, medium, and high supplementation. There was no difference (P > 0.10) in dry matter intake (DMI). However, animals receiving medium and high supplementation had decreased (P < 0.10) forage dry matter intake (FDMI) compared with those under non- and low supplementation. The DMI and FDMI were lower (P < 0.10) in the dry season. During the rainy season, the grazing time decreased (P < 0.10) for animals receiving supplementation compared with non-supplemented ones, but was similar between medium and high supplementation. The performance and carcass characteristics were greater (P < 0.10) for high and medium supplementation compared with low and control. In conclusion, increasing the supplementation plans for beef cattle in tropical pastures increases the nutrient intake but decreases FDMI. The performance also increases with the supplementation plan; however, the growth rate is affected by the grazing season. |

Os animais foram mantidos em pastagem com Brachiaria decumbens em quatro períodos: transição águas-seca, seca, transição seca-águas e águas. Quarenta e quatro animais (11 por tratamento) foram distribuídos aleatoriamente em um dos quatro planos nutricionais de suplementação definidos pela quantidade de suplemento ofertada: controle (somente mistura mineral), baixo, médio e alto plano de suplementação. Não houve diferença (P > 0,10) no consumo de matéria seca (CMS). No entanto, os animais que receberam médio e alto plano de suplementação reduziram (P < 0,10) o consumo de matéria seca de forragem (CMSF) comparado ao controle e baixo plano. O CMS e CMSF foram menores (P < 0,10) durante o período seco. Durante a estação chuvosa, o tempo de pastejo reduziu (P < 0,10) para os animais que receberam suplementação em comparação ao controle, mas foi semelhante entre os planos médio e alto. O desempenho e as características de carcaça foram maiores (P < 0,10) para o alto e médio plano comparados ao baixo e controle. Conclui-se que o aumento nas suplementações para bovinos de corte em pastagens tropicais aumenta a ingestão de nutrientes, mas diminui o consumo de forragem. O desempenho também aumenta com o plano de suplementação; no entanto, a taxa de crescimento é afetada pela época do ano.UEL2019-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3524810.5433/1679-0359.2019v40n6Supl2p3233Semina: Ciências Agrárias; Vol. 40 No. 6Supl2 (2019); 3233-3248Semina: Ciências Agrárias; v. 40 n. 6Supl2 (2019); 3233-32481679-03591676-546Xreponame:Semina.
