Resumo: | In the present work, with whole plant silage corn at different stages of maturity, aimed to evaluate the mathematical models Exponential, France, Gompertz and Logistic to study the kinetics of gas production in vitro incubations for 24 and 48 hours. A semi-automated in vitro gas production technique was used during one, three, six, eight, ten, 12, 14, 16, 22, 24, 31, 36, 42 and 48 hours of incubation periods. Model adjustment was evaluated by means of mean square of error, mean bias, root mean square prediction error and residual error. The Gompertz mathematical model allowed the best adjustment to describe the gas production kinetics of maize silages, regardless of incubation period. The France model was not adequate to describe gas kinetics of incubation periods equal or lower than 48 hours. The in vitro gas production technique was efficient to detect differences in nutritional value of maize silages from different growth stages. Twenty four hours in vitro incubation periods do not mask treatment effects, whilst 48 hour periods are inadequate to measure silage digestibility. |

Utilizou-se a técnica in vitro semiautomática de produção de gases (TIVPG) determinando o volume de gases com uma, três, seis, oito, dez, 12, 14, 16, 22, 24, 31, 36, 42 e 48 horas de incubação. Avaliou-se o ajuste dos modelos através do quadrado médio do erro, viés médio, raiz quadrada do erro médio de estimativa e erro residual. O modelo matemático de melhor ajuste para descrever a cinética de produção de gases in vitro em forragens de milho foi o Gompertz, para ambas as incubações de 24 e 48 horas. O modelo France não é adequado para descrever a cinética de produção de gases com tempos menores ou iguais a 48 horas de incubação. A técnica in vitro de produção de gases foi eficiente em detectar diferença no valor nutricional de silagens de milho produzidas em diferentes estádios de maturidade. Incubações in vitro por 24 horas não mascaram os efeitos dos tratamentos na ensilagem, enquanto tempos de 48 horas são inadequados para mensurar a digestibilidade da matéria orgânica de silagens de milho.UEL2014-09-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa empírica de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1397010.5433/1679-0359.2014v35n4Suplp2531Semina: Ciências Agrárias; Vol. 35 No. 4Supl (2014); 2531-2540Semina: Ciências Agrárias; v. 35 n. 4Supl (2014); 2531-25401679-03591676-546Xreponame:Semina.
