3:1. This explanation might account for the faster onset of
gas flammability of poultry blended system in the current
study, unlike the other blends which may contain only the
native microbial flora. The result of the microbial loads
during the digestion period shows that the population of
microbes was still high even when the experiment was
tending to end (Table 3). The CP: CD had the same onset
of gas flammability as the CP: PD even though the
cumulative gas yield was the least. Cow dung has been
acknowledged as the best biogas producer amongst
most animal wastes. As such it was expected that combining
it with the cassava peels should improve its gas
yield, however, this did not happen but only affected the
onset of gas flammability. Probably the synergy in existence
between cow dung and cassava peels is low when
compared to other wastes.
