Evaluation of Multi‐Breed Genomic Prediction Models for Carcass and Reproductive Traits in Zebu Beef Cattle

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Genomic prediction in beef cattle is particularly challenging in breeds with limited phenotypic and genotypic data. In this context, multi‐breed methodologies that integrate information from genetically related populations have emerged as a promising strategy to improve prediction accuracy and calibration under data‐scarce conditions.

Prevalence of cystic echinococcosis among livestock in pastoral and agro-pastoral areas in Uganda

Parasitology
Cystic echinococcosis (CE) remains a significant challenge in Uganda with precise status largely undocumented in most communities. To determine CE prevalence, post-mortem examination was done on 14 937 livestock (5873 goats, 1377 sheep, 3726 zebu cattle ...

Whole blood transcriptome profiles of trypanotolerant and trypanosusceptible cattle highlight a differential modulation of metabolism and immune response during infection by Trypanosoma congolense

Peer Community Journal, 2023
Animal African trypanosomosis, caused by blood protozoan parasites transmitted mainly by tsetse flies, represents a major constraint for millions of cattle in sub-Saharan Africa.

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).

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.

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.
