In ET technique, the embryos produced out of elite cow and buffalo is transferred to a recipient animal which acts as a surrogate mother and carries the embryo to full term. ET is a technique to increase the reproduction rate of genetically superior females – to get more calves in a life time than possible through normal reproduction. However, for ET one needs reproductively healthy animals. An embryo cannot be transferred using an AI gun and requires specialized skills and transfer equipment.
No, ET is not an alternative to AI to get the animal conceived. If the cow is not conceiving through AI, the animal will not even conceive through ET.
ET services cannot be provided at farmer’s level on individual basis. However ET is being carried out by a few organisations in India namely, SAG, Bidaj (Gujarat), PBGSBS, Haringhata (West Bengal), PLDB, Chandigarh, (Punjab), ULDB, Dehradun (Uttarakhand) and BAIF, Pune (Maharashtra) to produce HGM bulls for semen production.
No, ET does not provide a choice on the sex of the calf.
