The objective of this study was to evaluate effect of faeces sources used as inocula on in vitro gas production for
future applied studies. The experiment was conducted at Department of Animal Sciences, College of Agriculture
of Can Tho University. It was a factorial design (5*4) with 4 replications. Factor 1 was five sources of faeces
from buffalo (BF), cattle (CF), pig (PF), goat (GF) and rabbit (RF). The factor 2 was 4 feeds including Para grass
(PG), sesbania grandiflora (SG), rice straw (RS) and pineapple peel (PP). The measurements of gas production
were at 3, 6, 9, 12, 24, 48, 72 and 96 h. The results showed that gas production of five source of faeces were
significantly different (Pand significantly higher (Pin vitro gas production of PP was the highest
values and significantly different (Pwas that all faecal sources of the study could be used as inocula for in in vitro gas production and goat faeces
was the most potential for applications.
