Resumo: | The aim of this study was to evaluate the effect of three types of rotational pasture: isolated (I – grazing only by sheep), simultaneous (S – simultaneous grazing by cattle and sheep) and alternated (A – granzing by cattle and then by sheep) on the structural and chemical traits of grass. Twelve crossbreed heifers, weighing initially 207 kg, 30 Santa Inês lambs, weighing 23 kg, and 16 adult ewes weighing 47 kg were used. The following parameters were determined on the pasture: forage mass available per grazing cycle (FMC); proportion of leaf (PF); stalk (PS); dead material (PDM), leaf:stalk ratio (L/S); levels of dry matter (DM); mineral matter (MM); crude protein (PB); ether extract (EE); neutral detergent fiber (NDF); acid detergent fiber (ADF); inorganic phosphorus (Pi) and total digestible nutrients (TDN). The S and I systems presented the smallest values for PS and NDF, while their values for L/S, CP, EE and TDN were higher than in A system. Therefore, the results showed that the grass offered to sheep in S and I systems had better quality than in the A system. There was not effect of systems and cycles of pasture on the others parameters evaluated. Tanzania grass available to sheep showed best structural and chemical traits in S and I systems while it presented worse quality in A system. The S system may be an alternative to traditional sheep rearing systems in the Brazilian savannah region.KEYWORDS: grass; pasture; ruminant. |

O delineamento foi inteiramente casualizado, em fatorial 3x3 (sistemas de pastejo x ciclos de pastejo). Utilizaram-se 12 bovinos (mestiços), com peso médio de 207 kg, 16 ovelhas adultas com 47 kg e 30 cordeiros com peso médio de 23 kg da raça Santa Inês. As seguintes variáveis foram avaliadas: massa de forragem disponível por ciclo de pastejo (MFP); proporções de folhas (PF), colmo (PC) e material morto (PMM); relação folha:colmo (F/C); teores de matéria seca (MS), matéria mineral (MM), proteína bruta (PB), extrato etéreo (EE), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), fósforo inorgânico (Pi) e nutrientes digestíveis totais (NDT). Os tratamentos BO e O apresentaram menores valores para as variáveis PC e FDN, ao mesmo tempo em que foram superiores em F/C, PB, EE e NDT em relação ao tratamento BDO, denotando melhor qualidade do capim oferecido aos ovinos nesses dois tratamentos. Nas demais variáveis não houve efeito dos sistemas e nem dos ciclos de pastejo. O sistema de pastejo simultâneo pode ser considerado uma alternativa de manejo ao sistema isolado de ovinos na região de cerrado brasileiro.PALAVRAS-CHAVE: gramínea; pastagem; ruminantes.Universidade Federal de Goiás2011-12-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionresearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlapplication/pdfhttps://revistas.ufg.br/vet/article/view/994610.5216/cab.v12i4.9946Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 12 No. 4 (2011); 670-680Ciência Animal Brasileira / Brazilian Animal Science; v. 12 n. 4 (2011); 670-6801809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/9946/10040https://revistas.ufg.br/vet/article/view/9946/10041https://revistas.ufg.br/vet/article/view/9946/12341Santos, Viviane Rodrigues V. dosLouvandini, HelderMcManus, ConceptaBrito, Daianainfo:eu-repo/semantics/openAccess2012-01-30T12:21:41Zoai:ojs.revistas.ufg.br:article/9946Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:44.266123Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
