Wild birds are considered natural reservoirs of Newcastle disease virus (NDV) and some common resident or migratory wild birds are associated with outbreaks of ND in commercial poultry in Pakistan. Continuous isolation of new genotypes in Pakistan shows the evolving nature of the virus and the emergence of new strains is limiting in its diagnosis and control. Pakista...

The conjugated linoleic acid (C18:2∆9c,11t) content was significantly higher in milk fat ewes fed CF1 (0.97%). These results indicate that the FA profile and total tocopherols are significantly affected by the diet type.
