Resumo: | The aim of this thesis was to evaluate the performance of Andropogon grasses (Andropogon gayanus Kunth), Buffel (Cenchrus ciliary L.) cv. Grass and Massai (Panicum maximum x Panicum infestum) at ages 21, 35, 49 and 63 days. The experiments were carried out at the Federal Institute of Education, Science and Technology of Rio Grande do Norte - IFRN Campus Apodi, in the period from June to December 2014. The evaluations were carried out in two stages, which yielded three scientific papers. In the first stage, information was addressed regarding the forage species, which were emphasized morphogenetic and structural characteristics and the production and chemical composition of corn in different regrowth ages. In the second stage, it was shown the evaluation of animal performance using hay of the three studied forages, which analyzed the nutrient intake, feeding behavior and sheep performance. For morphogenic and structural evaluation the andropogon presented late vegetative development, contrary to the development presented by buffel grass. Grasses Andropogon, Buffel and Massai increase the production of dry matter with advancing age of regrowth, the andropogon showed higher growth rates of dry matter (469.41%). It occurred only difference between the grasses and Andropogon Massai, from 49 days of regrowth. The crude protein, neutral detergent fiber and lignin components were more varied with increasing regrowth period in all forage species. In assessing the performance of animals fed with hay, it was observed that the regrowth ages influenced rumination, reducing its efficiency with advancing age. The daily weight gain of the animals fed the massaigrass hay and grass Andropogon hay did not differ, but differed from the buffel grass hay. The daily weight gain was not influenced by the age of grasses. Overall analysis showed that the thesis information interrelation helped to determine the best way to choose the forage species to the region, reaching the conclusion that in the conditions, the Massai and Andropogon grasses stood by vegetative best performance and best responses to animals. |

Grass e Massai (Panicum maximum x Panicum infestum) nas idades de 21, 35, 49 e 63 dias. Os experimentos foram desenvolvidos no Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte – IFRN, Campus Apodi, no período de junho a dezembro de 2014. As avaliações foram realizadas em duas etapas, que geraram três artigos científicos. Na primeira etapa, foram abordadas informações referentes às espécies forrageiras, onde foram enfatizadas as características morfogênicas e estruturais e a produção e composição química das gramíneas nas diferentes idades de rebrota. Na segunda etapa, foi evidenciada a avaliação do desempenho animal utilizando o feno das três forrageiras estudadas, onde foi analisado o consumo de nutrientes, comportamento ingestivo e o desempenho de ovinos. Para avaliação morfogênica e estrutural o capim-andropogon apresentou desenvolvimento vegetativo tardio, contrário ao desenvolvimento apresentado pelo capim-buffel. Os capins Andropogon, Buffel e Massai aumentam a produção de matéria seca com o avanço da idade de rebrota, o capim-andropogon apresentou maiores crescimentos de matéria seca (469,41%). Ocorreu diferença apenas entre os capins Massai e Andropogon, a partir dos 49 dias de rebrota. A proteína bruta, a fibra em detergente neutro e a lignina foram os componentes que mais variaram com o aumento do período de rebrota em todas as espécies forrageiras estudadas. Na avaliação de desempenho dos animais, alimentados com feno, foi observado que as idades de rebrota influenciaram a ruminação, diminuindo sua eficiência com o avanço da idade. O ganho de peso diário dos animais alimentados com o feno de capim-massai e feno de capim-andropogon não diferiram entre si, mas diferiram do feno de capim buffel. O ganho de peso diário não foi influenciado pela idade dos capins. Em análise geral, observou-se que a inter-relação de informações da Tese contribuiu para determinar a melhor forma de eleger a espécie forrageira para a região, chegando-se a conclusão que, nas condições apresentadas, os capins Massai e Andropogon se destacaram pelo melhor desempenho vegetativo e melhores respostas aos animais2017-04-13application/pdfhttp://repositorio.ufersa.edu.br/retrieve/1519/GenildoFP_TESE.pdf.jpgporUniversidade Federal Rural do Semi-ÁridoPrograma de Pós-Graduação em Ciência AnimalUFERSABrasilCC-BY-SAinfo:eu-repo/semantics/openAccessAndropogon gayanusCenchrus ciliarisForragemPanicum maximumOvinosAndropogon gayanusCenchrus ciliarisForagePanicum maximumSheepCNPQ::CIENCIAS AGRARIAS::MEDICINA VETERINARIADesempenho de gramíneas tropicais no semiáridoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisreponame:Biblioteca Digital de Teses e Dissertações da UFERSAinstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAORIGINALGenildoFP_TESE.pdfGenildoFP_TESE.pdfapplication/pdf914555https://repositorio.ufersa.edu.br//bitstream/tede/639/1/GenildoFP_TESE.pdfd228a0712f89f6d40a7d44bfd5b02841MD51LICENSElicense.txtlicense.txttext/plain; charset=utf-82165https://repositorio.ufersa.edu.br//bitstream/tede/639/2/license.txtbd3efa91386c1718a7f26a329fdcb468MD52TEXTGenildoFP_TESE.pdf.txtGenildoFP_TESE.pdf.txtExtracted Texttext/plain121184https://repositorio.ufersa.edu.br//bitstream/tede/639/3/GenildoFP_TESE.pdf.txt0a04f684210cbb7b2aae72de62fafaafMD53THUMBNAILGenildoFP_TESE.pdf.jpgGenildoFP_TESE.pdf.jpgGenerated Thumbnailimage/jpeg3095https://repositorio.ufersa.edu.br//bitstream/tede/639/4/GenildoFP_TESE.pdf.jpg43408bd9fb80a0deff9ff23cea40b151MD54tede/6392022-06-03 14:42:43.402oai:repositorio.ufersa.edu.br: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Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufersa.edu.br/PUBhttp://bdtd.ufersa.edu.br/oai/requestdirecaosisbi@ufersa.edu.br|| direcaosisbi@ufersa.edu.bropendoar:2022-06-03T17:42:43Biblioteca Digital de Teses e Dissertações da UFERSA - Universidade Federal Rural do Semi-Árido (UFERSA)false |
