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

Abstract

This study investigates the impact of beneficial organisms on sheep m ethane emissions usi ng the Affordable Face Mask (ABC ) technique. Methane, a potent greenhouse gas from ruminant microbial fermentation, has a high global warming potential. The research, conducted at Chittagong Veterinary and Animal Sciences University (CVASU), Bangladesh, involves four sheep (T1, T T2, C C1, C C2) divided into treatment (T1, T T2,) and control (C1, C 2) groups. Acclimatizing the animals to the face masks ensures precise data collection. An inexpensive face mask was devised, linked to a plastic tank for gas collection. Blood samples were taken before and after the experiment to gauge Blood Urea (BU) and B lood Urea Nitrogen (BUN) levels. Gas capture occurred at specific intervals, with masks placed over the nose and mouth, analys ing exhaled and inhaled breath for ten minutes. Data underwent STATA STATA-13 analysis to unveil patterns. Results showed a slight decre decrease (6.5%) methane emissions at 3 hours after morning feeding in the treatment group compared to the control group that indicate those microorganisms have a positive impact on the rumen microbial population and fermentation. Av erage per animal methane emi ssion from Treatment Group ( 69.45 l/d) which is lower than Control Group (77.54 l/d ).
