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.

Genome sequencing of the extinct Eurasian wild aurochs, Bos primigenius, illuminates the phylogeography and evolution of cattle [PDF]

, 2015
Background Domestication of the now-extinct wild aurochs, Bos primigenius, gave rise to the two major domestic extant cattle taxa, B. taurus and B. indicus.

Treatments to Optimize the Use of Artificial Insemination and Reproductive Efficiency in Beef Cattle under Tropical Environments

Veterinary Medicine International, 2011
Bos indicus cattle, the preferred genetic group in tropical climates, are characterized by having a lower reproductive efficiency than Bos taurus. The reasons for the poorer reproductive efficiency of the Bos indicus cows include longer lengths of ...

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.

Evaluation of Adaptive, Productive and Reproductive Performance of Boran Dairy Breed in the Lowland Agro‐Ecology of Kaffa Zone, South‐Western Ethiopia

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Boran dairy cattle demonstrated acceptable productive, reproductive and adaptive performance under lowland conditions of south‐western Ethiopia. Significant effects of parity and lactation stage were observed on milk yield and blood parameters, while physiological values remained within normal ranges, confirming good adaptation and potential for ...

Population Structure, and Selection Signatures Underlying High-Altitude Adaptation Inferred From Genome-Wide Copy Number Variations in Chinese Indigenous Cattle

Frontiers in Genetics, 2020
Copy number variations (CNVs) have been demonstrated as crucial substrates for evolution, adaptation and breed formation. Chinese indigenous cattle breeds exhibit a broad geographical distribution and diverse environmental adaptability. Here, we analyzed
