PRODUCCIÓN DE BIOGAS Y CH4 IN VITRO A PARTIR DE EXCRETAS DE BOVINOS, OVINOS, CERDOS Y GALLINAS

Abstract

The objective of this present investigation was compared the biogas and methane production in (liter) in vitro digesters from excrement of cattle, sheep, pigs and hen, with a ratio of 1:4 in 1 liter nominal capacity jars. In relation to the biogas production, the excrement of hen was the higher (27.1 L/kg of excrement), in relation to the methane production, the excrement of sheep was the higher (8.3 L of methane/kg of excrement). a completely randomized design was used, with four treatment and six repetitions. The variables were analyzed in an ANOVA using the PROC GLM of the SAS. And for the differences between treatments was used the Tukey test
