Abstract: The genetic potential of cows can be harvested by recent techniques like ultrasound guided ovum-pickup technique (In-vivo) and aspiration of oocytes from (SO) slaughter house ovaries (In-vitro) and subsequently production of embryo by IVF for transfer. However Unproductive, infertile or sterile genetically superior cows are regularly culled at farms. These cows do not have any commercial value and are ultimately sent to gaushalas. The aim of the present research was to study the maturation potential of immature oocytes recovered in vivo from unproductive cows by ultrasound guided ovum-pickup technique (OPU).
