Plasma Pharmacokinetic Profile of Fipronil 1% Pour‐On in Cattle: Photodegradation and the Sustained Systemic Persistence of Fipronil Sulfone

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT This study characterized the long‐term pharmacokinetic profile of a 1% fipronil pour‐on formulation in Nellore bulls under field conditions. Seventeen animals received a single topical dose (1 mg/kg), and plasma concentrations of fipronil and its metabolites (sulfone and desulfinyl) were monitored for 175 days using LC–MS/MS.

Coding and Noncoding Uterine Small Extracellular Vesicle Content Differs in the Early Stages of Pregnancies Produced by Artificial Insemination and In Vitro Fertilization in Cattle

Molecular Reproduction and Development, Volume 93, Issue 7, July 2026.
ABSTRACT Establishing a successful pregnancy relies on effective communication between the mother and fetus. Small extracellular vesicles (sEVs) are pivotal in facilitating intercellular communication, transferring messenger RNA (mRNA), noncoding RNA (ncRNA), and proteins. Considering the prevalence of in vitro fertilization (IVF) in bovine production,

Status of On‐Farm Artificial Insemination Services and Effectiveness of Oestrus Synchronization in Dairy Cattle Under Small‐Scale Dairy Farming System

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Cross‐sectional survey and retrospective data on the oestrus synchronization were collected and analysed. The predominant mating system practiced by dairy farmers was AI (55.6%), and 73.5% of farmers apply controlled mating. The highest response rate and pregnancy rate were 89.5% and 45.2%, respectively, whereas a birth rate of 9.6%–18.5% was obtained.
