Agricultural biotechnology for poverty alleviation: one more arrow in the quiver! por Seré Rabé, Carlos, Rege, J.E.O.

“…Similarly in animal production there is substantial opportunity for development of vaccines and diagnostics targeting diseases which constrain livestock production in developing regions of the world. In addition, genetic markers can aid breeding of livestock for important traits such as disease resistance, improved product quality as well as improved productivity. …”
