EFFECT OF BENEFICIAL ORGANISM ON GOAT METHANE EMISSION ESTIMATED BY THE LOW-COST ABC METHOD

Abstract

Methane emissions from livestock, particularly ruminants like goats, contribute significantly to greenhouse gas emissions and global warming. This report investigates the influence of beneficial organism on methane production on goats, utilizing two distinct groups, a control group and a treatment group where beneficial organism were introduced. The Chattogram Veterinary and Animal Sciences University's goat farm served as the study's site. We used Portable gas detector which is specifically designed to measure methane (CH4) concentrations in the eructed air breath of goats and provides concentration values in parts per million (ppm). Statistical analysis revealed a significant decrease in methane emissions, suggesting that this organism has a positive impact on the rumen's microbial population and fermentation processes. Result showed a high decrease (122.09%) methane emission at 3 hours after morning feeding in the treatment group compared to the control group. Average methane emission from control group was 7.22 l/kg B.W. and from treatment group was 5.57 l/kg B.W.
