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 ...
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 ...
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 ...
In vitro evaluation of Lactobacillus plantarum as direct-fed microbials in high-producing dairy cows diets
(2019-12-21)
The objectives of this study were: 1) to compare the effects of live yeast (LY), yeast fermentation product (YFP), a mix of Lactobacillus acidophilus and Propionibacterium freudenreichii (MLP), and Lactobacillus plantarum ...
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 ...
Producción de biomasa y costos de producción de pastos Estrella Africana (Cynodon nlemfuensis), Kikuyo (Kikuyuocloa clandestina) y Ryegrass Perenne (Lolium perenne) en lecherías de Costa Rica
Dry matter yield and production costs in grazing systems on dairy farms of Costa Rica
(2013-12-11)
Se evaluó la producción de biomasa, los costos de producción y el costo del kilogramo de materia seca en los pastos kikuyo (Kikuyuocloa clandestina), ryegrass perenne (Lolium perenne) y estrella africana (Cynodon nlemfuensis), ...
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 ...
