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 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 ...
Effects of partially replacing dietary corn with sugars in a dual-flow continuous culture system on the ruminal microbiome
(2023)
The objective of this study was to evaluate the effects of feeding sugars as a replacement for starch on the ruminal microbiome using a dual-flow continuous culture system. Four periods of 10 days each were conducted with ...
Effects of calcium-magnesium carbonate and calciummagnesium hydroxide as supplemental sources of magnesium on ruminal microbiome
(2022)
Our objective was to evaluate the inclusion of calcium-magnesium carbonate [CaMg(CO3
)
2
] and calcium-magnesium hydroxide [CaMg(OH)4
] in
corn silage-based diets and their impact on ruminal microbiome. Our previous ...
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. ...
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 ...
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). ...
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 ...
Effects of lactic acid-producing bacteria as direct-fed microbials on the ruminal microbiome
(2022)
The objective of this study was to evaluate ruminal
microbiome changes associated with feeding Lactobacillus plantarum GB-LP1 as direct-fed microbials (DFM)
in high-producing dairy cow diets. A dual-flow continuous culture ...
