Effects of neutral detergent fiber digestibility estimation method on calculated energy concentration of canola meals from 12 Canadian processing plants
(2021)
Our aim was to determine whether the method used to estimate truly digestible neutral detergent fiber (tdNDF) affects
calculated concentrations of total digestible nutrients (TDN1x) and net energy of lactation (NEL3x) of ...
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 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, ...
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 ...
Effects of unprotected choline chloride on microbial fermentation in a dual-flow continuous culture depend on dietary neutral detergent fiber concentration
(2021-03)
Choline is usually supplemented as ruminally protected choline chloride to prevent its degradation in the
rumen, but the effects of unprotected choline on ruminal fermentation are unclear. Some research indicates a ...
Shrink, weighing accuracy, and weighing precision of mineral supplement in five commercial dairies in the Western United States
(2021-05-10)
Shrink, accuracy, and precision of
ingredient weighing are critical factors of effi ciency in TMR-fed dairy systems. Those factors
have been evaluated for major feeds; however,
we are not aware of any reports for ...
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 ...
Copper sulfate and sodium selenite lipid-microencapsulation modifies ruminal microbial fermentation in a dual-flow continuous-culture system
(2020-08)
Undesirable interactions between trace mineral ele ments and ruminal contents may occur during digestion
when mineral salts are supplemented. Antimicrobial
effects of copper sulfate (CuSO4) may affect ruminal
digestibility ...
