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 ...
Costos de producción de ensilados de pastos tropicales elaborados en lecherías de Costa Rica
Production costs of tropical grasses-based silages in dairy farms in Costa Rica
(2015-10)
Se evaluó el costo de ensilajes elaborados con pastos perennes de piso (kikuyo y estrella africana), de corte (maralfalfa y mombaza) y anuales (avena forrajera, maíz y sorgo) en 31 lecherías de Costa Rica ubicadas en las ...
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 ...
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 ...
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 ...
Efecto del picado sobre las características nutricionales y fermentativas de ensilajes de pastos kikuyo, ryegrass perenne y alpiste forrajero
Effect of chopping on the nutritional and fermentative characteristics of kikuyu, perennial ryegrass and reed canary grass based silages
(2016-08-27)
Se evaluó el efecto del picado sobre las características nutricionales y fermentativas de ensilajes elaborados con 3 pastos (kikuyo, ryegrass perenne y alpiste forrajero). Se elaboraron 2 microsilos de cada pasto en bolsas ...
