Explanations:

Calculation of theoretical manure potential

Y_M = N_A · M_i

where:

Y_M – theoretical manure potential (Mg/year)

N_A – number of animals (number)

M_i – the indices of average manure production:

Animal	Mg per animal per year
Cattle	14.8
Pigs	1.5
Sheep	1.2
Horses	5.0
Goats	1.0
Chickens	0.035
Turkeys	0.06
Ducks	0.06
Geese together with guinea fowls	0.04

Calculation of manure biogas yield

Q_M = Y_M · B_c

where:

Q_M – biogas yield potential of manure (m³/year)

Y_M– theoretical manure yield (Mg/year)

B_c – biogas conversion coefficient:

Calculation of manure biomethane yield

Q_MCH4 = Y_M · BM_c

where:

Q_MCH4 – biomethane yield potential of manure (m³/year)

Y_M– theoretical manure yield (Mg/year)

BM_c – biomethane conversion coefficient:
