Enhanced Free Fatty Acid Production From Goat and Cow Milk: Conventional and Ultrasound‐Assisted Lipolysis of Whole and Disrupted Fat Globules

open access: yesEuropean Journal of Lipid Science and Technology, EarlyView.
The graphical abstract illustrates the combined use of physical pretreatments—high‐shear dispersing (HSD), stirring (ST), and high‐pressure homogenization (HPH)—to reduce fat globule size in goat and cow milk creams, enhancing enzymatic hydrolysis.

Effects of Dietary Forage Proportion on Feed Intake, Growth Performance, Nutrient Digestibility, and Enteric Methane Emissions of Holstein Heifers at Various Growth Stages

open access: yesAnimals, 2019
Enteric methane (CH4) emissions from young ruminants contribute to a substantial proportion of atmospheric CH4 accumulation. Development of emission inventory and mitigation approaches needs accurate estimation of individual emission from animals under ...

Laminitis in dairy cows

open access: yesJournal of the Hellenic Veterinary Medical Society, 2018
Laminitis is currently considered one of the commonest causes of lameness in dairy cows in Greece. Nutrition, especially rations based on concentrated feedstuffs, herd management and genetic factors are involved in the etiopathogenesis of the disease. The causative agents, formed usually in the digestive tract, reach the heels via systemic circulation,

Heat stress related dairy cow mortality during heat waves and control periods in rural Southern Ontario from 2010–2012

open access: yesBMC Veterinary Research, 2015
BackgroundHeat stress is a physiological response to extreme environmental heat such as heat waves. Heat stress can result in mortality in dairy cows when extreme heat is both rapidly changing and has a long duration.

Development of ruminating behavior in Holstein calves between birth and 30 days of age

open access: yesJournal of Dairy Science, 2022
: Ruminating behavior accompanies the development of the rumen and the intake of solid feed in calves. However, few studies have reported on the emergence and development of rumination.

Metagenomic Analysis of Antibiotic Resistance Genes in Dairy Cow Feces following Therapeutic Administration of Third Generation Cephalosporin

open access: yesPLoS ONE, 2015
Although dairy manure is widely applied to land, it is relatively understudied compared to other livestock as a potential source of antibiotic resistance genes (ARGs) to the environment and ultimately to human pathogens.

Functional analysis of Parabacteroides distasonis F4: a novel probiotic strain linked to calf growth and rumen fermentation

open access: yesJournal of Animal Science and Biotechnology
Background Rumen microorganisms are key regulators of ruminant growth and production performance. Identifying probiotic candidates through microbial culturomics presents a promising strategy for improving ruminant production performance.

Understanding the functionality of the rumen microbiota: searching for better opportunities for rumen microbial manipulation [PDF]

open access: yesAnimal Bioscience
Rumen microbiota play a central role in the digestive process of ruminants. Their remarkable ability to break down complex plant fibers and proteins, converting them into essential organic compounds that provide animals with energy and nutrition ...

A Dairy Cow Body Condition Scoring System and Its Relationship to Selected Production Characteristics

open access: yes, 1982
A scoring system with 1 to 5 scale was devised to measure body condition of dairy cows at any point during the lactation cycle. Cows were scored on appearance and palpation of back and hind quarters only.
