Megasphaera elsdenii and Saccharomyces Cerevisiae as direct fed microbials during an in vitro acute ruminal acidosis challenge
(2022)
This study aimed to evaluate the efects of Saccharomyces cerevisiae and Megasphaera elsdenii as
direct fed microbials (DFM) in beef cattle fnishing diets to alleviate acute ruminal lactic acidosis
in vitro. A dual-fow ...
Effects of bacterial cultures, enzymes and yeast-based feed additive combinations on ruminal fermentation in a dual-flow continuous culture system
(2021)
Bacterial cultures, enzymes, and yeast-derived feed additives are often included in commercial dairy rations due to their effects on ruminal fermentation. However, the effects of these additives when fed together are not ...
Effects of partially replacing dietary corn with molasses, condensed whey permeate, or treated condensed whey permeate on ruminal microbial fermentation
(2022)
Corn is a feedstuff commonly fed to dairy cows as
a source of energy. The objective of this study was to
evaluate whether partially replacing dietary corn with
molasses or condensed whey permeate, in lactating
dairy ...
Effects of calcium–magnesium carbonate and calcium–magnesium hydroxide as supplemental sources of magnesium on microbial fermentation in a dual-flow continuous culture
(2020-12-22)
Supplemental sources of Mg can
also aid in ruminal pH regulation due to their al kaline properties. Magnesium oxide (MgO) is the
most common source of Mg for ruminants and
can help controlling ruminal pH; however, ...
The Effects of Incremental Doses of Aflatoxin B1 on In Vitro Ruminal Nutrient Digestibility and Fermentation Profile of a Lactating Dairy Cow Diet in a Dual-Flow Continuous Culture System
(2023)
Aflatoxin B1
(AFB1
) is a mycotoxin known to impair human and animal health. It is also
believed to have a deleterious effect on ruminal nutrient digestibility under in vitro batch culture
systems. The objective of ...
Adaptation of in vitro methodologies to estimate the intestinal digestion of lipids in ruminants
(2021)
The objective of this study was to adapt existing in vitro methodologies to determine the extent of intestinal digestion of corn oil (CO), canola oil (CA), and beef tallow (BT) via manipulation of incubation length and ...
Effects of replacing magnesium oxide with calcium-magnesium carbonate with or without sodium bicarbonate on ruminal fermentation and nutrient flow in vitro
(2022)
The objective of this study was to evaluate the effects of replacing magnesium oxide (MgO) with calcium-magnesium carbonate [CaMg(CO3)2] on ruminal
fermentation with or without the addition of sodium
bicarbonate (NaHCO3). ...
Effects of supplemental source of magnesium and inclusion of buffer on ruminal microbial fermentation in continuous culture
(2021-07)
Magnesium oxide (MgO) is the most common supple mental source of Mg for dairy cows and a proven ruminal alkalizer when supplemented above NRC (2001)
recommendations. However, overfeeding MgO may
increase feeding costs, ...
Combinations of bacterial cultures, exogenous enzymes, and yeast-based feed additives and their impact on ruminal microbiome
(2022)
Our objective was to evaluate the effects of bacteria (Lactobacillus animalis, Propionibacterium freudenreichii, Bacillus lichenformis, Bacillus
subtilis, and Enterococcus faecium), enzymes (amylase, hemicellulose, and ...
