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 exogenous amylolytic or fibrolytic enzymes inclusion on in vitro fermentation of lactating dairy cow diets in a dual-flow continuous-culture system
(2023)
The objective of this study was to determine the
effects of including exogenous amylolytic or fibrolytic
enzymes in a diet for high-producing dairy cows on in
vitro ruminal fermentation. Eight dual-flow continuousculture ...
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 ...
In vitro evaluation of microencapsulated organic acids and pure botanicals as a supplement in lactating dairy cows diet on in vitro ruminal fermentation
(2023)
The utilization of microencapsulated organic acids and pure botanicals (mOAPB) is widely used in the monogastric livestock industry as an alternative to antibiotics; in addition, it can have gut immunomodulatory functions. ...
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, ...
Effects of cashew nut-shell extract and monensin on microbial fermentation in a dual-flow continuous culture
(2023-09-09)
The objective of this study was to compare cashew nut-shell extract (CNSE) to monensin and evaluate
changes in in vitro mixed ruminal microorganism fermentation, nutrient digestibility, and microbial nitrogen
outflow. ...
Production, physiological response, and calcium and magnesium balance of lactating Holstein cows fed different sources of supplemental magnesium with or without ruminal buffer
(2023)
The objective of this study was to evaluate the effects
of dietary replacement of magnesium oxide (MgO) with
calcium-magnesium hydroxide [CaMg(OH)2] and its interaction with ruminal buffer (sodium sesquicarbonate)
sup ...
Can dietary magnesium sources and buffer change the ruminal microbiota composition and fermentation of lactating dairy cows?
(2023)
Magnesium oxide (MgO) is one of the most used Mg supplements in livestock. However, to avoid relying upon only one Mg source, it is important to have alternative Mg sources. Therefore, the objective of this study was to ...
