Nili-Ravi is also known as Panch Kalyani. The home tract of Nili-Ravi buffaloes is the belt between the Sutluj and Ravi rivers of the undivided Punjab Province. Actually Nili & Ravi were two different breeds long before, but due to the passage of time and with intensive crossbreeding, the two breeds converted into single breed named Nili-Ravi. Nili-Ravi buffaloes are found in almost all the districts, with major concentration in Amritsar, Gurdaspur and Ferozepur districts of Indian Punjab and in Lahore, Sheikhupura, Faizabad, Okora, Sahiwal, Multan, Bohawalpur and Bahwalnagar districts of Pakistan Punjab. The name Nili is supposed to have been derived from the blue water of river Sutluj. It is very easy to identify the animals of this breed. Animals have walled eyes and white markings on forehead, face, muzzle, legs and tail. The most desired character of female is the possession of these white markings known as "Panch Kalyani". The animals are good milkers and comparable to Murrah in all aspects except the color. The average milk production of the buffalo is 1850 kilograms with 6.8 % fat. The lactation yield ranges from 1586 to 1929 Kg.
