Resumo: The objective of this study was to determine the chemical composition, the carbohydrates fractionation and the kinetics of in vitro ruminal fermentation of fibrous and non-fibrous carbohydrates of five sugarcane varieties. Variety SP79-1011 presented the highest value of total digestible nutrients (65.9%), followed by the varieties Java, RB72454, SP80-1842 and RB765418. For the accumulated gas in the dry matter, 48 and 96 horas of in vitro incubation were higher for the variety SP79-1011, showing significant difference in comparison with the varieties RB765418, RB72454 and SP80-1842, excepting the variety Java that did not show any difference in relation the first one. The dry matter partitioning factor decreased with the incubation time and there was no difference among the evaluated varieties. The characteristics of the production cycle influenced the in vitro ruminal fermentation of the evaluated varieties, being the varieties of precocious cycle (SP80-1842 and RB765418) the ones with the worst results. Amongst the varieties tested, SP79-1011 and Java presented the best results of gas production kinetics and total digestible nutrients.KEYWORDS: In vitro true degradability, gas production, Saccharum officinarum.

O objetivo deste trabalho foi determinar a composição química, o fracionamento dos carboidratos e a cinética da fermentação ruminal in vitro dos carboidratos não fibrosos e carboidratos fibrosos de cinco variedades de cana-de-açúcar. A variedade SP79-1011 apresentou o maior teor de nutrientes digestíveis totais (65,9%), seguida das variedades Java, RB72454, SP80-1842 e RB765418. A produção acumulada de gases na matéria seca às 48 e 96 horas de incubação in vitro foi maior para a variedade SP79-1011, apresentando diferença significativa em comparação com as variedades RB765418, RB72454 e SP80-1842, exceção feita à variedade Java, que apresentou valores semelhantes à primeira. O fator de partição da matéria seca diminuiu com o aumento no tempo de incubação, sendo que não houve diferença entre as variedades avaliadas. As características do ciclo de produção influenciaram na fermentação ruminal in vitro nas variedades avaliadas, sendo que as de ciclo precoce SP80-1842 e RB765418 foram as que apresentaram resultados inferiores. Dentre as variedades testadas, as variedades SP79-1011 e Java apresentaram os melhores resultados de cinética de produção de gases e nutrientes digestíveis totais comparativamente superiores.PALAVRAS-CHAVES: Degradabilidade verdadeira in vitro, produção de gases, Saccharum officinarum.Universidade Federal de Goiás2010-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPESQUISA CIENTÍFICAapplication/pdftext/htmlapplication/pdfhttps://revistas.ufg.br/vet/article/view/480410.5216/cab.v11i4.4804Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 11 No. 4 (2010); 784 - 793Ciência Animal Brasileira / Brazilian Animal Science; v. 11 n. 4 (2010); 784 - 7931809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/4804/8352https://revistas.ufg.br/vet/article/view/4804/8719https://revistas.ufg.br/vet/article/view/4804/10265Cruz, Pedro Gomes daFigueiredo, Mauro Pereira dePereira, Luiz Gustavo RibeiroBergamaschi, Keityane BooneRodrigues, Carlindo SantosRech, Carmen Lúcia de Souzainfo:eu-repo/semantics/openAccess2010-12-21T13:36:26Zoai:ojs.revistas.ufg.br:article/4804Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:17.433626Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
