Evaluation of performance and carcass traits for a five-cohort All Heifer, No Cow beef production system demonstration herd
(2020-10-27)
The All Heifer, No Cow (AHNC)
beef production system is an alternative to con ventional cow/calf production that involves in semination of nulliparous heifers with sexed
semen to produce female calves that are early ...
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 commercial and farm-made inoculants on the chemical composition and fermentation of kikuyu grass silages
(2022-03)
Ensiling allows for more efficient pasture utilization in kikuyu (Cenchrus clandestinus Hochst. ex Chiov.)-based forage systems. However, the chemical composition of kikuyu challenges this process. Additives can improve ...
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 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 ...
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 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). ...
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 ...
