Resumo: The study was conducted to evaluate fermentation kinetic of diets based on cactus forage enriched with urea and Tifton 85 hay, containing different starch sources, using semi-automated in vitro gas production technique. Treatments were disposed in a randomized block design, with four replications, where concentrates were formulated as follows: cassava roots (FSMa), semi flint corn grains (FSMiSD), dent corn grains (FSMiD) and wheat bran (FTMa). All diets were formulated to obtain 15% of crude protein. Gas pressure were measured 2, 4, 6, 8, 10, 12, 15, 18, 21, 24, 30, 36, 48, 72 and 96 h after inoculation. For fast phase maximum gas volume (Vf1), both treatments containing corn did not differ (P>0.05). FTMa differed (P<0.05) from diets composed with corn, as main starch source. Specific degradation rate of fast fraction (Kd1) was higher (P<0.05) on FSMa and FTMa diets, compared with corn diets. Colonization time (L) showed lower values (P<0.05) for FTMa diet. The lowest total gas production was observed on FTMa and the highest for FSMiD, varying from 225.49 to 268.31 mL/g, respectively. Cassava roots as starch source contributes to a faster fermentation, compared to both corns, allowing a better synchronization with faster degradation nitrogen sources.

Os tratamentos (dietas) foram dispostos em um delineamento em blocos casualizados, com quatro repetições, sendo os concentrados compostos como segue: farelo de soja e raiz de mandioca (FSMa), farelo de soja e milho semiduro (FSMiSD), farelo de trigo e mandioca (FTMa) e farelo de soja e milho dentado (FSMiD). As dietas foram formuladas para obter teores de 15% de proteína bruta na matéria seca. A pressão dos gases foi mensurada às 2, 4, 6, 8, 10, 12, 15, 18, 21, 24, 30, 36, 48, 72 e 96 h após a inoculação. Para o volume de produção de gases dos carboidratos não fibrosos nas primeiras 6 horas de fermentação os tratamentos contendo as duas variedades de milho (FSMiSD e FSMiD) não diferiram entre si (P>0,05) enquanto que, o FTMa diferiu (P<0,05) das dietas que continham milho como fonte principal de amido. A taxa específica de degradação da fração rápida (Kd1) foi maior nas dietas compostas por FSMa e FTMa quando comparada às contendo milho. O tempo de colonização (L) foi menor (P<0,05) na dieta com FTMa, quando comparado às demais. A produção total de gases foi menor para o tratamento FTMa e maior para o FSMiSD, variando de 225,49 mL/g a 268,31 mL/g, respectivamente. A utilização da mandioca como fonte de amido proporciona uma fermentação mais rápida, quando comparada ao milho, permitindo melhor sincronização com fontes de nitrogênio de rápida degradação.UEL2014-06-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo científicoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1328910.5433/1679-0359.2014v35n3p1501Semina: Ciências Agrárias; Vol. 35 No. 3 (2014); 1501-1514Semina: Ciências Agrárias; v. 35 n. 3 (2014); 1501-15141679-03591676-546Xreponame:Semina.
