The paper deals with biogas yield production from two co-substrates - sorghum silage mixture of corn silage and crushed potatoes combined with mixture of livestock manure and swine slurry - in a semi-continuous digester under mesophilic conditions. This paper aims to evaluate the suitability of alternative substrates for biogas production under biogas plant operational conditions. In the first experiment, biogas yield was 0.159 Nm3 per hour with methane content of 56.96% vol. In the second
