Crossbreeding Local Sheep with Rambouillet




  • Sheep are kept primarily for mutton production in the country but wool is an important secondary product. Wool produced in the country is of coarse type and is used for carpet manufacturing. Khutta breed of sheep is indigenous in Swat. It is small sized breed (average adult weight: 26.5 kg) and has medium quality wool (average wool fibre diameter: 30.3µ).

    Sheep are kept primarily for mutton production in the country but wool is an important secondary product. Wool produced in the country is of coarse type and is used for carpet manufacturing. Khutta breed of sheep is indigenous in Swat. It is small sized breed (average adult weight: 26.5 kg) and has medium quality wool (average wool fibre diameter: 30.3µ).  A Rambouillet breeding flock was imported from the USA. The flockCrossbreeding_Local_Sheep_with_Rambouillet was kept at the Livestock Research Station, Jaba to upgrade the native sheep.  Crossbreeding was carried out by distributing more than 4,000 purebred Rambouillet rams in Malakand, Hazara, Azad Jammu and Kashmir and Gilgit area. Technical backstopping was also provided to the participating sheep farmers.

    This programme became a huge success. More than 90 percent of the sheep populations in Swat and Kaghan valleys are now crossbred. Body weight of the crossbred sheep is higher than local breed (23 % improvement). Similarly wool production increased from 0.8 kg to 1.8 kg (118% improvement) and wool quality improved from a fibre diameter of 30.3µ to 21.1µ. The price of the wool increased three times because of its improved quality and increased demand by the local industry. The farmers’ income increased by 30 % per sheep sold. The programme is continuing.
