Scientists at Central Sheep and Wool Research Institute (CSWRI), Avikanagar, Rajasthan have come up with new laparascope-assisted insemination technique for sheep breeding. It is minor invasive laparascopic technique involves passing rigid fibre-optic laparoscope into abdomen through small incision. Using it, reproductive tract of sheep is located through camera and frozen semen is deposited into uterus.
Significance of new technique
The new technique has resolved difficulties involved in freezing of semen and inability to transit tortuous reproductive tract of sheep kept as livestock. Earlier, success with frozen semen in sheep was very low because of its poor freezability.
The new technique will also help achieve up to 60% survival in birth of lambs. Moreover, it will have immense potential for rapid multiplication of elite germplasm. Using this technique, as many as 40 females can be inseminated from a single ejaculate. It will also be of great help in the breed improvement programmes.
