We detected orthopoxvirus in 28 of 125 serum samples collected during 2009 from cattle in Uruguay. Two samples were PCR-positive for vaccinia virus and had sequences similar to those for vaccinia virus associated with outbreaks in Brazil. Autochthonous circulation of vaccinia virus in Uruguay and other South American countries cannot be ruled out.

This study was carried out at Alkhurmah Governorate; Taif, Kingdom of Saudi Arabia (KSA).Thirty weaned males of Najdi sheep aged between 3-4 months with average body weight 22.87±.0.18 kg were used for study. Animals were allotted to three comparable groups (10 lambs/each), the first group served as control (fed ration composed of 60% concentrate feed mixture (CFM) plus 40 % alfalfa hay) while ...

Infectious Bovine Rhinotracheitis is a highly contagious disease caused by the bovine herpes virus-1 (BoHV-1), resulting in significant losses to livestock around the world. BoHV-1 is a major pathogen of cattle, primarily associated with respiratory/genital tract infections and abortion.

The communal grazing system is generally understood to have a low input, low output type of management. However, the actual inputs and outputs of the farmers are not well known and the farmers are often unaware of their problems. Although the causes of low calving percentage are well understood in commercial beef farming enterprises in South Africa, the same is not true for communal farming sys...
