Serological controls for diseases of viral origin in animal production systems and the identification factors associated with infections are decisive elements to establish prevention control measures. The aim this study was serological status Bovine Viral Diarrhea (BVD) Enzootic Leukemia (EBL) viruses Blanco Orejinegro (BON) cattle from Colombia, identify seropositivity. A cross-sectional condu...

We give several different formulations for the discrete-time linear-quadratic control problem in terms of structured eigenvalue problems, and discuss the relationships among the associated structured objects: symplectic matrices and pencils, BVD-pencils and polynomials, and the recently introduced classes of palindromic pencils and matrix polynomials. We show how these structured objects can be...

Bovine viral diarrhea (BVD) is a disease that affects cattle and other ruminants worldwide causes considerable economic losses. A cross-sectional study was carried out between December 2017 July 2018 with the aim to estimate prevalence of Viral Diarrhea virus (BVDV) antibodies identify potential risk factors associated occurrence in dairy peri-urban areas Gondar city, Northwest Ethiopia. total ...

The experimental objective was to evaluate safety of spray-dried plasma protein after oral administration in weanling pigs by monitoring clinical, serological, and performance results. Thirty-six pigs (13.6 kg body weight) were randomly assigned to dietary treatments consisting of control (soybean meal) or 8% plasma. Diets were formulated to contain 1.20% lysine due to continuous administration...

Challenges in eradicating BVD (bovine viral diarrhoea) include lack of farmer motivation, difficulties in encouraging compliance with biosecurity and testing protocols, and variations in opinions regarding responsibility to eradicate the disease (gunn and others 2005, Booth and Brownlie 2012). a coordinated approach, industry support, farmer cooperation, achievable targets and effective communi...
