Using Supervised Machine Learning Algorithms to Predict Bovine Leukemia Virus Seropositivity in Florida Beef Cattle: A 10‐Year Retrospective Study

Journal of Veterinary Internal Medicine, Volume 39, Issue 3, May/June 2025.
ABSTRACT Background Bovine leukemia virus (BLV) infection in beef cattle has received less attention than in dairy herds, despite its potential impact on the beef industry. Objectives To compare six different supervised machine‐learning (SML) algorithms used to identify the most important risk factors for predicting BLV seropositivity in beef cattle in

Prevalence of Enzootic Bovine Leukosis in Bulgaria

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Veterinary Medicine, 2015
The Enzootic bovine leukosis (EBL) is broadly spread on all continents. Due to the lack of specific means for prevention and treatment, it turns to be a serious health and economic issue for a number of countries with developed cattle farming. The aim of the present study was to establish the prevalence of EBL in Bulgaria in 2012 and the effect of the ...
