Genetic variability of 10 microsatellite markers in the characterization of Brazilian Nellore cattle (Bos indicus)

Genetics and Molecular Biology, 2006
We assessed the polymorphism of 10 microsatellites in Brazilian Nellore cattle (Bos indicus) using a commercial multiplex system. Allele frequencies, polymorphism information content, heterozygosity and exclusion probability were calculated.

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, Volume 49, Issue 5, Page 515-524, September 2026.
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.

Cow Milk Risk Factors Associated With Bacterial Contaminations Along Dairy Value Chain in Lushoto and Handeni Districts, Tanzania

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Milk and milk products are important sources of nutrients to human and animals, but due to its physicochemical characteristics and nutritional value, it serves as an excellent medium for growth of microorganisms. Most of smallholder dairy farmers have no training on livestock husbandry and milk handling practices.

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.
