Abstract

The study aimed to determine the influence of addition of Sida hermaphrodita silage into cattle forage on efficiency of methane fermentation of cattle manure. Efficiency of methane fermentation connected with amount and composition of produced biogas was determined with respirometric tests. Methane fermentation was performed in mesophilic conditions with initial organic compounds loading of 5 g VS/(dm3∙d). The study was divided into two stages. In first stage, substrate in methane fermentation was only cattle manure. In second stage, substrate in methane fermentation was cattle manure and Sida silage. There were three series of experiments in each stage, due to cattle manure was obtained from cattle fed with forage differ in contribution of Sida silage (0 – series 1, 17% - series 2, 34% - series 3). In the stage 1, biogas production of 223±15 L/kg VS, 247±8.5 L/kg VS and 231±18 L/kg VS was noted in the series 1, 2, and 3, respectively. The addition of Sida silage to the cattle forage had no impact on biogas potential of cattle manure. In the stage 2, the same tendency was observed. No differences in biogas composition between series were also observed. Methane content in biogas was about 60%.
