Evaluation of manure production from different livestock is important for business planning in bioenergy sector. According to proposed legislation, share of animal sourced byproducts, including manure, can be limitative for application on state aid for new biogas plant building and for feed-in tariff calculation for purchase of electricity produced in biogas plants. For calculation purposes, livestock was divided into 11 different groups, and animals in every group have approximately same manure output per head in a year. Manure resources from dairy cow were calculated with consideration of average milk yield within every parish or municipality in Latgale planning region. Biogas potential obtainable from livestock manure was 11.2 million m3, including 77.6% from cattle 17.4% from pigs, 4.5% from poultry and 0.5% from horses in planning region Latgale in 2011.
