Australian Friesian Sahiwal
This breed is being developed in Australia by the Queensland Government for use in the tropical areas. The breed was evolved using the Sahiwal, a dairy strain of Zebu from Pakistan, and the Australian Holstein-Friesian.

Since the 1960’s when research work began on this breed, notable progress has been achieved towards the objective of combining tick resistance and heat tolerance with reliable milk production and fertility. It has now been extensively tested in the tropical and sub-tropical areas of Australia. Under these conditions, it outperforms the Holstein Friesian by approximately 15 percent.

Average milk yield is 3,000 liters for mature cows. Milk quality is good - protein level is 3.4 percent and butterfat is approximately four percent.
