Murrah buffalo

The Murrah buffalo is a breed of water buffalo ("Bubalus bubalis") mainly kept for milk production. It originates in Punjab and Haryana states of India, where it is kept in the districts of Bhiwani, Hisar, Rohtak, Jind, Jhajhar, Fatehabad, Gurgaon and the capital region of Delhi. A Murrah buffalo at the Lakshmi Dairy Farm in Punjab set a record of 26.335 kg of milk in the 2016 National Livestock Competition and Expo.
It has been used to improve the milk production of dairy buffalo in other countries, such as Italy, Bulgaria, and Egypt. 
In Brazil, this breed of buffalo is used for production of both meat and milk. Murrahs sell for a high price.
Among Indian buffalo breeds, Murrah is noted to have the highest milk yield.
