The Effect of Oral Calcium Boluses and Subcutaneous Calcium Injection on Blood Metabolites and Milk Yield in Holstein Cattle Fed Anionic Diets

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Oral calcium supplementation modestly improved early postpartum plasma ionized Ca and reduced ketone body concentrations, suggesting moderated metabolic benefits. No effects on milk yield and fertility were found. Further research with larger sample sizes may be warranted to confirm these findings.

Antioxidants promote metabolic remodeling in cattle rumen epithelium revealed by single‐cell resolution

iMeta, Volume 4, Issue 6, December 2025.
Single‐cell and transcriptomics from 1.79 million cells identify the forestomach epithelium as the dominant site of antioxidant activity and oxidative phosphorylation (OXPHOS) in the bovine gastrointestinal tract. Along the basal‐to‐luminal differentiation axis, antioxidant capacity and OXPHOS rise in a coordinated metabolic–redox gradient.

Antimicrobial prescribing guidelines for horses in Australia

Australian Veterinary Journal, Volume 103, Issue 12, Page 781-889, December 2025.
The growing problem of antimicrobial resistance also affects equine veterinarians with increasing frequency. Antimicrobial stewardship and responsible prescribing are essential for a future in which effective antimicrobials are available, as it is unlikely that new antimicrobials will become available for use in horses.

Determination of antioxidant indices in dairy cows during the periparturient period [PDF]

Acta Veterinaria Brno, 2019
The aim of the present study was to evaluate indicators of antioxidant status – glutathione peroxidase (GPx); superoxide dismutase (SOD); total antioxidant status (TAS); vitamins A, E and beta carotene in 10 dairy cows of the Holstein breed from 15-20 days ante partum (a.p.) to 25–30 days post partum (p.p.). Blood samples were collected 5 × during this

Randomised controlled field trial to assess the safety and efficacy of a killed autologous vaccine against Streptococcus dysgalactiae subspecies dysgalactiae in a sheep flock

Veterinary Record, Volume 197, Issue 10, Page e256-e263, 15/22 November 2025.
Abstract Introduction Joint‐ill in neonatal lambs, primarily caused by Streptococcus dysgalactiae subspecies dysgalactiae (SDSD), results in increased mortality and morbidity. An effective vaccine is needed to prevent the disease. Methods A blinded randomised controlled trial was carried out using an autologous SDSD vaccine in a commercial sheep flock ...

Complementary Muscle Metabolomics and Proteomics of Muscle in Cows With Post‐Calving Ketosis

Journal of Veterinary Internal Medicine, Volume 39, Issue 6, November/December 2025.
ABSTRACT Background The muscle tissue of dairy cows is a site of β‐hydroxybutyrate (BHBA) metabolism. The mechanisms underlying the changes in proteins and metabolites in the muscle tissue of cows with ketosis remain unclear. Objectives To elucidate the metabolic and physiological molecular adaptation mechanisms in the muscle tissue of cows with ...

Effects of Summer Heat on Adipose Tissue Activity in Periparturient Simmental Cows

Metabolites
Hot climate is one of the major factors affecting the dairy industry. Heat stress could be responsible for decreased feed intake and consequently leads to alterations in energy metabolism, particularly during late pregnancy and early lactation.

Research on Laying Trichostrongylid Nematode Eggs in Cows in the Periparturient Period

Turkish Journal of Parasitology, 2017
This study aimed to comparatively determine the prevalence of trichostrongylid nematodes and egg excretions in cows that are in the periparturient period (PPP) and pregnant cows in the non-periparturient period (NPPP).Animal materials are constituted by cows in PPP and NPPP in 10 ranches in Kars and surrounding areas.

Effects of supplementing a Saccharomyces cerevisiae fermentation product during the periparturient period on performance of dairy cows fed fresh diets differing in starch content.

Journal of Dairy Science, 2019
The objective of this study was to evaluate the effects of supplementing a Saccharomyces cerevisiae fermentation product (SCFP; NutriTek, Diamond V, Cedar Rapids, IA) during the periparturient period (d -28 ± 3 to 44 ± 3 relative to calving) on dry ...
