Rumen fermentation and microbial community composition influenced by live Enterococcus faecium supplementation.

Supplementation of appropriate probiotics can improve the health and productivity of ruminants while mitigating environmental methane production. Hence, this study was conducted to determine the effects of Enterococcus faecium SROD on in vitro rumen fermentation, methane concentration, and microbial population structure. Ruminal samples were collected from ruminally cannulated Holstein-Friesian cattle, and 40:60 rice straw to concentrate ratio was used as substrate.

Effects of illite supplementation on in vitro and in vivo rumen fermentation, microbial population and methane emission of Hanwoo steers fed high concentrate diets.

This study was conducted to evaluate the effects of feeding supplemental illite to Hanwoo steers on methane (CH ) emission and rumen fermentation parameters. An in vitro ruminal fermentation technique was conducted using a commercial concentrate as substrate and illite was added at different concentrations as treatments: 0%, 0.5%, 1.

Use of Lysozyme as a Feed Additive on Rumen Fermentation and Methane Emission.

This study was conducted to determine the effect of lysozyme addition on rumen fermentation and to identify the lysozyme inclusion rate for abating methane (CH) production. An ruminal fermentation technique was done using a commercial concentrate to rice straw ratio of 8:2 as substrate. The following treatments were applied wherein lysozyme was added into 1 mg dry matter substrate at different levels of inclusion: Without lysozyme, 2,000, 4,000, and 8,000 U lysozyme.
