An initiative by scientist of NRC on Mithun to produce artificially inseminated calf of Mithun for the first time in Khonoma village under Kohima district was successfully carried out as field trial for the benefit of farmers. Following the artificial insemination, one of the cows gave birth to healthy male calf on May 6.
Artificial insemination (AI) has become one of the most important techniques ever devised for the genetic improvement of farm animals.
Although AI has been practicing in other livestock like cattle, buffalo etc but in Mithun it has been practiced only in institute farm level.
Considering it, an approach was made recently to percolate this technology to farming situation and accordingly Mithun rearing areas of Khonoma village was selected for this programme under the leadership of Dr. C. Rajkhowa, Director, NRC on Mithun, Jharnapani, Nagaland. The team comprised of Dr, K. K. Baruah, Dr. M. Mondal, Dr B. Bora, Dr. Ritu Raj Borah and Dr. K. Khate.
Two Mithun cows were synchronised into oestrus by using protocol developed at Institute. Cryopreserved semen samples were used for inseminating the healthy mithun cows. The semen samples were collected from genetically superior bulls and cryopreserved in liquid nitrogen using tris-egg yolk-glycerol diluent.
The mithun cows were inseminated using cryopreserved semen. All the cows were conceived following insemination.
