Resumo: | The objective of this work was to evaluate the botanical composition, the availability and quality of the fodder and diet of fistulated animals fed in an area of Caatinga, during the rainy season, in Pernambuco State, Brazil. Evaluations of botanical composition and fodder availability of herbaceous, arbustive and arboreous extracts were made in March and June. Fodder quality evaluation was performed through chemical analysis during the wet period. Sixty-seven species were found: 28 herbaceous, 20 arbustive and 18 arboreal; from these species, 19 were found in the animals diet. The fitomass availability from the herbaceous component varied from 1,369 kg ha-1 of dry matter (DM) in March, to 452 kg ha-1 of DM in June. The availability of the arbustive extract layer was close to the herbaceous, while the arboreal component contributed with only 178 kg ha-1 of DM. Despite the relatively high fitomass availability, only a small percentage was considered as fodder from the material found. It was observed a low digestion of the protein, probably due to high levels of lignin. |

Avaliaram-se a composição botânica e a disponibilidade de fitomassa dos estratos herbáceo, arbustivo e arbóreo, nos meses de março e junho. A avaliação da qualidade da forragem foi feita por meio da análise bromatológica, realizada em todos os meses do período chuvoso. Foram encontradas 67 espécies, das quais 28 herbáceas, 20 arbustivas e 19 arbóreas. Destas, 19 foram encontradas na dieta dos animais. A disponibilidade de fitomassa do componente herbáceo variou de 1.369 kg ha-1 de matéria seca (MS), em março, para 452 kg ha-1 de MS em junho. A disponibilidade do estrato arbustivo aproximou-se do herbáceo, enquanto o componente arbóreo contribuiu com apenas 178 kg ha-1 de MS. Apesar de a disponibilidade de fitomassa ser relativamente alta, apenas uma pequena porcentagem do material encontrado pode ser considerada como forragem. Foi observada baixa digestibilidade da proteína, provavelmente em conseqüência do alto teor em lignina.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMoreira, José NiltonLira, Mário de Andradedos Santos, Mércia Virginia FerreiraFerreira, Marcelo de AndradeAraújo, Gherman Garcia Leal deFerreira, Rinaldo Luiz Caracioloda Silva, Grécia Cavalcanti2006-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7328Pesquisa Agropecuaria Brasileira; v.41, n.11, nov. 2006; 1643-1651Pesquisa Agropecuária Brasileira; v.41, n.11, nov. 2006; 1643-16511678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7328/4373info:eu-repo/semantics/openAccess2014-10-06T18:14:57Zoai:ojs.seer.sct.embrapa.br:article/7328Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-06T18:14:57Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
