The proportion of C2 and methane were
decreased, while C3 proportion was increased by the supplementation. It was found
that all supplemented treatments had no effects on Ruminococcus albus, Fibrobacter
succinogenes and Ruminococcus flavefaciens populations (P40.05), whereas total
bacteria and total methanogens populations were affected by supplementation
(Po0.05). Total bacteria were the highest in control group and lowest when supplemented
with Mago-pel and Maga-lic.
