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.

Survey of Smallholder Dairy Cattle Farming System and Antibiotic Residues in Raw Cow's Milk in Bagamoyo District, Tanzania

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Smallholder dairy farmers in Tanzania face livestock disease challenges that drive imprudent antimicrobial use and fuel antimicrobial resistance (AMR). In Bagamoyo, poor husbandry and limited disease control result in high prevalence of vector‐borne infections, commonly treated with oxytetracycline (OTC).

Production objectives, trait and breed preferences of farmers keeping N’Dama, Fulani Zebu and crossbred cattle and implications for breeding programs

Animal, 2017
Many local livestock breeds in developing countries are being replaced by exotic breeds, leading to a loss of genetic resources. In southern Mali, for the past two decades, a trend towards increasing crossbreeding between the trypanotolerant N’Dama ...

Prevalence of Mastitis in Cows and Raw Milk Microbial Contamination in Selected Districts, Tanzania

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Cow milk produced in Tanzania suffers from poor quality due to bacterial contamination from mastitis udder predisposed by poor livestock husbandry and milk hygienic practices. The prevalence of mastitis was 75.6%, with a milk bacterial contamination rate of 78% and resistance to multiple antimicrobials. To safeguard the dairy industry and public health,

Genetic Relationships Between Residual Gain and Economically Important Traits in Nellore Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 5, Page 658-666, September 2026.
ABSTRACT Sustainable beef production requires identifying animals with superior feed efficiency to reduce environmental impact and production costs. This study aimed to estimate heritability and genetic correlations between residual gain (RG) and growth, reproductive, carcass and feed efficiency traits in Nellore cattle.
