In this study we present systematic framework to analyse the impact of farm profiles as combinations of environmental conditions and management practices on common diseases in dairy cattle. The data used for this secondary data analysis includes observational data from 166 farms with a total of 5828 dairy cows. Each farm is characterised by features from five categories: husbandry, feeding, environmental conditions, housing, and milking systems. We combine dimension reduction with clustering techniques to identify groups of similar farm attributes, which we refer to as farm profiles. A statistical analysis of the farm profiles and their related disease risks is carried out to study the associations between disease risk, farm membership to a specific cluster as well as variables that characterise a given cluster by means of a multivariate regression model. The disease risks of five different farm profiles arise as the result of complex interactions between environmental conditions and farm management practices. We confirm previously documented relationships between diseases, feeding and husbandry. Furthermore, novel associations between housing and milking systems and specific disorders like lameness and ketosis have been discovered. Our approach contributes to paving a way towards a more holistic and data-driven understanding of bovine health and its risk factors.

Gut Microbial Composition and Antibiotic Resistance Profiles in Dairy Calves with Diarrhea.
Life (Basel)
December 2024
Department of Animal Engineering, Yangling Vocational & Technical College, Yangling 712100, China.
Calf diarrhea is a prevalent and significant health issue in dairy farming, severely impacting feed intake, weight gain, and survival rates in young calves. This study aimed to investigate the microbial composition and antibiotic resistance profiles of diarrheic calves to provide insights into the epidemiology and management of the condition. The prevalence of diarrhea in 1685 calves was analyzed.

Background: Antimicrobial resistance is one of the greatest challenges of our time, urging researchers in both veterinary and public health to engage in collaborative efforts, thereby fostering the One Health approach. Infections caused by species can not only lead to significant diseases in poultry but also pose serious threats to human life, particularly in hospital (nosocomial) infections; therefore, it is crucial to identify their antimicrobial resistance.
Methods: Our objective was to assess the susceptibility profile of commensal strains ( = 227) found in commercial chicken flocks in Hungary through the determination of minimum inhibitory concentration (MIC) values.
Monitoring the Spread of Multidrug-Resistant Throughout the Broiler Production Cycle.
Antibiotics (Basel)

Department of Microbiology, Biological Sciences Center, State University of Londrina, Londrina 86057-970, Brazil.
The extensive use of antimicrobials in broiler production is changing the bird microbiota, fostering drug-resistant bacteria, and complicating therapeutic interventions, making the problem of multidrug resistance global. The monitoring of antimicrobial virulence and resistance genes are tools that have come to assist the breeding of these animals, directing possible treatments as already used in human medicine and collecting data to demonstrate possible dissemination of multidrug-resistant strains that may cause damage to industry and public health. This work aimed to monitor broiler farms in southern Brazil, isolating samples of and classifying them according to the profile of resistance to antimicrobials of interest to human and animal health.

Porcine epidemic diarrhea (PED) is caused by the PED virus, with (), comprising and , being the primary contributors to outbreaks worldwide. In Thailand, was the only virulent strain identified until the emergence of the first strain in 2014, followed by additional strains in 2015-2016, particularly those closely related to virulent strains from China. This led to increased awareness of more frequent and complex outbreaks.

Animal feeding has a great impact on the management of beef farms, also affecting the nutritional properties of the meat. Therefore, in this study, the following two forage-to-concentrate ratios were tested on twenty farmed Podolian young bulls: high forage-to-concentrate (HF:C) ratio of 65:35 vs. low forage-to-concentrate (LF:C) ratio of 45:55.
