Resumo: An experiment was carried out to investigate the effects of supplementation strategies on intake, digestibility, and performance of Nellore cattle on pasture (Urochloa decumbens) during the rainy-dry transition period. The evaluated strategies were mineral supplementation (MS), self-feed supplementation (SF), and infrequent concentrate supplementation. Supplementation frequencies were three times per week (Mondays, Wednesdays, and Fridays - 3tw) and daily (7tw). Animals receiving concentrate supplementation had higher pasture DM and TDN intakes than those fed MS. There was no difference (P > 0.10) between concentrate supplementation strategies. Average pasture DM intake was 7.89, 8.09, and 8.10 kg day?1 for SF, 3tw, and 7tw, respectively. No effects were found (P > 0.10) between SF and infrequent supplementation, or for the supplementation frequencies tested. The lowest average daily gain (ADG) (P < 0.10) was found for animals fed MS, and there was no difference between concentrate supplementation strategies for this variable. Average daily gains for MS, SC, 3tw, and 7tw were 661.4, 812.7, 811.5 and 819.2 g/animal, respectively. During the rainy-dry transition period, grazing beef cattle receiving concentrate supplementation have higher pasture and TDN intakes and better performance than animals fed mineral supplement only. Self-feed supplementation or supplementation provided three days per week do not compromise pasture and TDN intakes, nutrient digestibility, or performance of grazing beef cattle.

As estratégias avaliadas foram: suplementação mineral (SM), a suplementação tipo autocontrole de consumo (AC) e suplementação infrequente. As frequências de suplementação avaliadas foram a três vezes/semana (segundas, quartas e sextas-feiras - 3X) e diariamente (7X). Os animais que receberam suplementação de concentrado apresentaram maior consumo de MS de pasto e NDT do que aqueles que receberam SM. Não houve diferença (P > 0,10) entre as estratégias de suplementação concentrada com média de ingestão de MS de 7,89; 8,09 e 8,10 kg dia-1, respectivamente, para AC, 3X e 7X. Nenhum efeito foi encontrado (P > 0,10) entre suplementação AC e as frequências estudadas que não diferiram entre si. Verificou-se menor ganho médio diário (GMD) (P < 0,10) para os animais alimentados com SM e não houve diferença entre as estratégias de suplementação concentrada. Os GMD foram de 661,4; 812,7; 811,5 e 819,2 g/animal, respectivamente para SM, AC, 3X e 7X. Durante a época de transição águas-seca, bovinos de corte que recebem suplementação concentrada apresentam maiores consumos de MS de pasto e de NDT e desempenho do que animais alimentados apenas com suplemento mineral. Suplementos tipo AC ou suplementos ofertados 3X/semana não impacta negativamente os consumos de pasto e de NDT, a digestibilidade dos nutrientes e o desempenho de bovinos criados a pasto.UEL2017-05-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2558910.5433/1679-0359.2017v38n2p895Semina: Ciências Agrárias; Vol. 38 No. 2 (2017); 895-908Semina: Ciências Agrárias; v. 38 n. 2 (2017); 895-9081679-03591676-546Xreponame:Semina.
