To improve the chances of successful production of hybrids, many important measures are taken. One such important programme is called Multiple Ovulation Embryo Transfer (MOET). During which, a cow is given hormonal treatment so that more than one ovule (6-8 .eggs) is produced per cycle. After mating or artificial insemination, the embryos at 8-32 celled stage are transferred to different surrogate mothers. The method has been successfully used for producing cattles, sheeps, buffaloes, etc.
