Regional Mithun Breeding Farm

The Regional Mithun Breeding Farm, Arong is located on the gentle slope at an altitude of 1400. It is 31 km from Samdrup Jongkhar along the Trashigang/Samdrupjongkhar highway. The vegetation is warm broad-leaved and is ideal for mithuns. Regional Mithun Breeding Farm was established in the year 1977. The farm had two stations till the end of 1994, one was at Arong where the breeding cows and calves < 1 year were kept and the other at Trashiyangphu, the present National Nublang Breeding Farm, kept mainly the growing stock. However the farm started with the initial stock of 2 heifers and 4 young bulls. At the moment the stock is 94 nos. The farm has a total area of 147.54 acres, out of which 136.76 are under improved pasture.

The Mithun (Bos frontalis) is known to be nocturnal
wanderer reared as high as 3500ft.Its yellow milk with 9.5% fat does not find
favour for human consumption. Mithun locally known as Bamey is domesticated
form of Gaur (Bos Gauras) locally known as Rilang. The use of mithuns for cross
breeding is very common amongst the cattle owners of Bhutan and dates back as early as
17th century. Mithun has continued to play an important role in the
religious and cultural life of the Bhutanese. The cross breeding produces FI
hybrids, Jatsha (male) and Jatsham (female). The males are popular for draught
power while the females are valued for high milk production. The animals are
easy to manage in difficult terrain and have the insatiable foraging ability.
Accordingly in view of the importance and the increasing demand of Mithun
bulls, the Royal Government established two Mithun farms during the 6th
five-year plan.



To produce purebred Mithun bulls for supply to the
farmers of six eastern dzongkhags so as to raise the nutritional standard of
the people in the country by increasing the productivity and production of milk
and milk products and at the same time to procure and supply from India.

  • To add to the strength of the country‚Äôs draught power mainly in
    the agricultural operations in the rural population and
  • To ensure the best present use and the long-term maintenance of
    the pure Mithun breed.


  • To manage the farm as a nucleus (for bull mother farm) to produce pure
    bred Mithun bulls for further supply to the farmers and to NDDC for semen
  • To fulfill the demand for Mithun bulls from the six eastern dzongkhags.


  • Proper planning to produce at least 10 nos. bulls annually by adopting
    appropriate reproductive management practices like heat detection,
    synchronization, pregnancy diagnosis, monitoring the natural service, treatment
    of reproductive defects and artificial insemination.
  • Provide health care and management by following proper schedule of
    deworming vaccination and providing clinical treatment whenever necessary.
  • Grazing management by creating grazing paddocks for rotational grazing
    to reduce the parasite burden and conservation of improved pasture.
  • Provide Mithun supplementary feed with concentrate, minerals and salt.
  • Develop farm infrastructure.


The farm has 137 acres under
improved pasture with established plantations consisting of Guatemala and
Napier plantations. Grazing paddock consisting of a mixture of molasses and
ruzi are also maintained. Fodder tree plantations inside the paddocks consist
of native fodder tree species.
