of liquid pig’s manure was founded after 20 days. There are microorganisms in liquid cattle manure, which decomposes the manure organie compounds. Cattle is a ruminant animal, in their rumen occur microorganisms such as hydrolysis of the genus MegasphaeraY.elsdenii, whichis already in the rumen converts macromolecules into their monomers. From methanogenic Methanomicrobium and Methanospiriillum bacteria exist in gut of ruminant animal. Therefore process of anacrobic fermentation

occurs morę rapidly and methane formation morę intensively in substrates from liquid cattle manure than with pig manure in experiments

[7].

The basie qualitative and quantitative features of biogas are formed from agricultural waste of the research study as follows: the percentage of methane in the biogas from liquid cattle manure is 63 % at normal conditions, the biogas from liquid pig manure is 57 % (Table 2).

Table 2

Substrates	Averagemethanecontent (%)	Average specific biogas yield (Nm^1 2 3/kg oDM)	Average specific methane yield (Nm^3/kg oDM)	Coefficient of variation (%) of specific methane yield	Average content of DM (% of fresh materiał)	Average content of oDM (% DM)
Liquid cattle manure	63	0,447	0,283	7,649	3,73	72,14
	57	0,339	0,196	29,846	2,11	66,15

Cattle and pig manures are the most abundant agricultural wastes. During the Processing of these wastes can be obtained biogas with methane content of 50-80%. The obtained results at 35 days hydrolytic retention time can be used to determine the dose and time of loading.
