EVALUATION OF BACTERIAL INVOLVEMENT IN AN EPISODE OF NEONATAL CALF DIARRHEA

AgroLife Scientific Journal, 2022
Diarrhea and digestive disorders represent one of the leading causes of mortality in calves during the first days of life. This study aimed to establish the level of antibiotic resistance of the flora identified in calves with digestive problems and also in their environment.

Diagnosis of bacteraemia in neonatal foals using 16S rRNA high‐throughput sequencing

Equine Veterinary Journal, EarlyView.
Abstract Background Sepsis is an important cause of morbidity and mortality in foals. Early diagnosis can improve outcome but is complicated by non‐specific clinical signs and delayed confirmation of infection via blood culture. Molecular assays represent a rapid and more sensitive alternative.

Current insights into neonatal calf diarrheal etiology and the therapeutic role of probiotics

Journal of Integrative Agriculture
Neonatal calves exhibit heightened susceptibility to infections caused by various gut microbiota, primarily due to their immature gastrointestinal barrier functions and underdeveloped immune systems during the pre-weaning period.

Harnessing microbial metabolism and nutrition to target the gut–mammary axis for better livestock production and health

iMetaOmics, EarlyView.
The gut–mammary axis integrates intestinal health with mammary function through neural, endocrine, and immune pathways. Nutritional interventions (probiotics, prebiotics, metabolites) improve gut microecology, generating microbial signals that travel via the axis to the mammary gland. There, they relieve inflammation, enhance milk quality and lactation,

Bile acid metabolism and signaling in human and animal health: A One Health perspective

iMetaOmics, EarlyView.
Bile acids maintain host homeostasis through enterohepatic circulation, microbial transformation, and bile acid receptor signaling, thereby regulating glucose and lipid metabolism, intestinal barrier integrity, and immunity. These effects support human disease intervention and health‐oriented animal production, reducing drug dependence and residue ...

Development of an IgY-Based Treatment to Control Bovine Coronavirus Diarrhea in Dairy Calves

Viruses, 2023
Bovine Coronavirus (BCoV) is a major pathogen associated with neonatal calf diarrhea. Standard practice dictates that to prevent BCoV diarrhea, dams should be immunized in the last stage of pregnancy to increase BCoV-specific antibody (Ab) titers in ...

Assessment of current colostrum feeding practices and passive transfer of immunity in dairy herds in Great Britain: A cross‐sectional study

Veterinary Record, EarlyView.
Abstract Background Updated targets for measuring transfer of passive immunity (TPI) at the herd level have been suggested, but the current performance of dairy herds in Great Britain is unknown. Methods A cross‐sectional study was performed. Serum total protein (STP) data collected between October 2022 and October 2023 by 21 veterinary practices were ...

Assessment of faecal calprotectin in neonatal calf diarrhoea using a human ELISA kit: Associations with faecal score and serum biochemical markers

Veterinary Record Open, Volume 13, Issue 2, December 2026.
Abstract Background Diarrhoea in newborn calves, which occurs in the first month of life and is caused by various pathogens, poses a significant threat to livestock industries. Therefore, timely diagnosis of enteritis in calves can be advantageous. Objective This study aimed to determine the efficacy of faecal calprotectin as a biomarker indicating ...
