Provide three crossbred milch cow examples?

Three well-known crossbred milch cow examples are:

1. Karan Fries – A cross between Holstein Friesian (exotic) and Tharparkar (indigenous), developed at the National Dairy Research Institute (NDRI), Karnal. It combines high milk yield with heat tolerance and adaptability.
2. Karan Swiss – Produced by crossing Brown Swiss (exotic) with Sahiwal (indigenous), also developed at NDRI, Karnal. It shows excellent milk production and good adaptability to tropical conditions.
3. Frieswal – A cross between Holstein Friesian (exotic) and Sahiwal (indigenous), developed by the Indian Council of Agricultural Research (ICAR) in collaboration with Indian military dairy farms. It combines high milk yield with disease resistance and heat tolerance.

Hence, Karan Fries, Karan Swiss, and Frieswal are three important crossbred milch cows known for their high milk yield and adaptability to Indian climates.
