Methane, in addition to being a significant source of energy loss to the animal that can range
from 0· 02 to 0· 12 of gross energy intake, is one of the major greenhouse gases being …

The dicarboxylic acids aspartate, fumarate, and malate stimulate lactate utilization by the
predominant ruminal bacterium, Selenomonas ruminantium. Malate stimulates lactate …

Rumen fermentation affects ruminants productivity and the environmental impact of ruminant
production. The release to the atmosphere of methane produced in the rumen is a loss of …

The effect of fumarate used as a feed additive on the reduction of methanogenesis in the
rumen was evaluated by in vitro experiments. The addition of fumarate to the culture of …

Fifteen potential precursors of propionate were tested for their ability to decrease CH4
production by ruminal fluid in vitro. Sodium acrylate and sodium fumarate produced the most …

This experiment was designed to investigate the effects of different concentrations (0, 0.33,
0.66, 0.99, and 1.32 g/L) of a twin-strain of Saccharomyces cerevisiae live cells on in vitro …

Chemical reactions are controlled either thermodynamically or kinetically. With kinetic
control, the profile of products formed depends on the substrate concentrations and enzyme …

Three approaches to decrease ruminal methanogenesis which vary from commercial
accepted (yeast) to well verified but yet to enter widespread practical usage (organic acids) …

Feeding cattle high-grain diets has brought concurrent problems with ruminal acidosis.
Grain overload in feedlot cattle has gained the most attention because of its economic …

The gastrointestinal microbial consortium in dairy cattle is critical to determining the
energetic status of the dairy cow from birth through her final lactation. The ruminant's …
