Resumo: | This study was realized to evaluate the dry matter intake, nutrient digestibilities, and animal performance of crossbred steers grazing Brachiaria brizantha cv. Marandu, during the rainy season. Thirty-three crossbred steers with an average weight of 203.5 ± 39.5 kg were distributed in a completely randomized design with three treatments and eleven replications. The results were analyzed using an ANOVA and a Tukey test with a 5% probability of error. The three experimental diets were: MSA – mineral salt ad libitum; MSU - mineral salt + urea ad libitum and PSU - protein supplementation (0.1% of body weight). The dry matter intake of forage and total dry matter intake were similar (P > 0.05) among treatments. The dry matter, organic matter, neutral detergent fiber, crude protein, ether extract, non-fibrous carbohydrates and total carbohydrates digestibilitities coefficients were influenced (P < 0.05) by treatments. The final body weight, average daily gain, and feed efficiency were similar (P > 0.05) among treatments. The supplementation strategies used during the rainy season resulted in a similar performance; therefore, the strategy adopted could be chosen according to the economical and regional conditions of the production. |

Marandu, durante la temporada de lluvias. Treinta y tres novillos mestizos, con peso medio de 203.5 ± 39.5 kg, fueron distribuidos en un diseño completamente aleatorizado con tres tratamientos y once repeticiones. Los resultados fueron analizados por ANOVA y las medias comparadas por análisis de Tukey con 5% de probabilidad de error. Las tres dietas experimentales fueron: MSA - sal mineral ad libitum; MSU - sal mineral + urea ad libitum; PSU - suplementación proteica (0,1% del peso corporal). La ingestión del forraje y la ingestión de la materia seca total fueron semejantes (P> 0,05) para todas las estrategias de suplementación. El coeficiente de digestibilidad de la materia seca, materia orgánica, fibra en detergente neutro, proteína cruda, extracto etéreo, carbohidratos no fibrosos y carbohidratos totales fueron influenciados (P < 0,05) por las estrategias de suplementación adoptadas. El peso corporal final, el promedio de ganancia diaria de peso y la eficiencia alimentar fueron semejantes (P > 0,05) entre las estrategias de suplementación. Las estrategias de suplementación utilizadas durante la época de lluvias resultaron en un desempeño semejante, sin embargo, la estrategia adoptada podría ser escogida de acuerdo con las condiciones económicas y regionales de la producción.Este trabalho foi realizado para avaliar a ingestão de matéria seca, a digestibilidade de nutrientes e o desempenho animal de novilhos mestiços em pastagem de Brachiaria brizantha cv. Marandu, durante a estação das chuvas. Trinta e três novilhos mestiços, com peso médio de 203,5 ± 39,5 kg foram distribuídos em delineamento inteiramente casualizado, com três tratamentos e onze repetições. Os resultados foram analisados por ANOVA e Tukey, com 5% de probabilidade de erro. As três dietas experimentais foram: MSA - sal mineral ad libitum; MSU - sal mineral + ureia ad libitum e PSU - suplementação proteica (0,1% do peso corporal). A ingestão de matéria seca da forragem e a ingestão de matéria seca total foram semelhantes (P > 0,05) entre os tratamentos. O coeficiente de digestibilidade da matéria seca, matéria orgânica, fibra em detergente neutro, proteína bruta, extrato etéreo, carboidratos não fibrosos e carboidratos totais foram influenciados (P < 0,05) pelos tratamentos. O peso corporal final, o ganho médio diário e a eficiência alimentar foram semelhantes (P > 0,05) entre tratamentos. As estratégias de suplementação utilizadas durante a estação chuvosa resultaram em desempenho semelhante, portanto, a estratégia adotada poderia ser escolhida de acordo com as condições econômicas e regionais de produção.Research, Society and Development2020-08-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/638410.33448/rsd-v9i9.6384Research, Society and Development; Vol. 9 No. 9; e15996384Research, Society and Development; Vol. 9 Núm. 9; e15996384Research, Society and Development; v. 9 n. 9; e159963842525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/6384/6134Copyright (c) 2020 Venicio Macedo Carvalho, Robério Rodrigues Silva, Túlio Otávio Jardim D`Almeida Lins, Mateus de Melo Lisboa, Maria Magna Silva Pereira, George Abreu Filho, João Wilian Dias da Silva, Sinvaldo Oliveira de Souza, Vicente Diaz Avila, Ivanor Nunes do Pradohttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCarvalho, Venício MacêdoSilva, Robério RodriguesLins, Túlio Otávio Jardim D`´AlmeidaLisboa, Mateus de MeloPereira, Maria Magna SilvaAbreu Filho, George Silva, João Wilian Dias daSouza, Sinvaldo Oliveira deAvila, Vicente DiazPrado, Ivanor Nunes do2020-09-18T01:42:11Zoai:ojs.pkp.sfu.ca:article/6384Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:33.054818Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
