Penicillin and Gentamicin Concentrations in the Uterine Fluid of Non‐Pregnant Mares Following a Single Intrauterine Infusion

Journal of Veterinary Pharmacology and Therapeutics, Volume 48, Issue 5, Page 389-396, September 2025.
ABSTRACT Despite their widespread clinical use, there is limited pharmacokinetic data for many equine intrauterine antimicrobials. This study aimed to measure the concentration of gentamicin and penicillin in the uterine fluid of mares following infusion of either a standard (PPGent) or long‐acting (LA‐PPGent) compounded formulation.

Rapid accumulation of polymorphonuclear neutrophils in the Corpus luteum during prostaglandin F(2α)-induced luteolysis in the cow. [PDF]

PLoS ONE, 2012
Prostaglandin F(2α) (PGF(2α)) induces luteolysis within a few days in cows, and immune cells increase in number in the regressing corpus luteum (CL), implying that luteolysis is an inflammatory-like immune response.

Foetal Mummification in Pregnant Dairy Cows Induces Variant Changes on the Hormonal Profile, Biochemical Parameters and Mineral Profile of the Dam

Veterinary Medicine and Science, Volume 11, Issue 3, May 2025.
A comprehensive investigation was conducted on the hormonal, biochemical, liver, kidney and mineral profiles of pregnant cows carrying mummified foetuses. The results showed a significant increase in glucose, albumin, triglycerides, cholesterol, globulin, total protein, urea, AST, ALP, bilirubin, iron and potassium in cows carrying mummified foetuses ...

Efficacy of Short‐Term Timed Artificial Insemination Protocols With Estradiol Esters and PGF2α in Girolando Cows

Reproduction in Domestic Animals, Volume 60, Issue 5, May 2025.
ABSTRACT Using a synchronisation protocol based on estradiol esters and prostaglandin, established in cattle since the 1970s, we implemented 24 or 48‐h intervals between hormone administration and timed artificial insemination (TAI). This study compared two short‐duration TAI protocols using estradiol benzoate (EB) and cypionate (EC) as ovulation ...
