Follicular dynamics in zebu cattle [PDF]

Pesquisa Agropecuária Brasileira, 2000
The aim of this study was to investigate the follicular dynamics during estrous cycle in Gir breed (Bos indicus) cows. Follicular growth and atresia during estrous cycle were evaluated using a portable ultrasound device. Luteal activity was evaluated by serum progesterone levels.

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.

Household‐Based Epidemiology of Bovine Ixodid Tick Infestation and Associated Risk Factors in Endamehoni, Raya‐Azebo and Enderta Districts, Tigray Region, Northern Ethiopia

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Tick infestation affected 41.5% of cattle in Tigray, with Rhipicephalus species predominating. Infestation was strongly associated with poor housing, poor body condition and management practices, whereas limited awareness of tick‐borne diseases highlights the need for targeted control strategies informed by species‐specific attachment‐site preferences.
