... for both commercial and backyard poultry production sectors. Owing to public health risk, effective control of the virus in imperative. DNA vaccination is a promising new approach for the prevention and treatment of many viral diseases because of its ability to induce both humoral and cellular immune responses against antigens encoded by recombinant DNA. The goal of this study was to construct Egy-H5 plasmid DNA-based vaccine against a currently circulating a...

Mostly dieticians recommend rabbit meat due to low in caloric value then other traditional meats. To enhance the quality of rabbit meat oat is used as feed for rabbits, because oat is good source of dietary ingredients. In this study 2-4% oat seeds were used to investigate their dietary response...
