Australian Milking Zebu facts for kids
The Australian Milking Zebu (AMZ) is a special type of dairy cow. It was created in Australia by scientists at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in the mid-1950s. These cows were bred to be good at producing milk, especially in warm climates. They are also strong against tiny pests called ticks.

What is the Australian Milking Zebu?
The Australian Milking Zebu, or AMZ for short, is a "composite breed" of cow. This means it's a mix of different cow breeds. Scientists carefully chose parent cows with the best traits to create the AMZ. They wanted a cow that could produce lots of milk even in hot places.
How the AMZ Breed Was Created
The CSIRO, a big science group in Australia, started developing the AMZ in the 1950s. They brought in two types of cows from Pakistan: the Sahiwal and the Red Sindhi cattle. These cows are known for doing well in hot weather.
They then bred these Pakistani cows with Jersey cattle. Jersey cows are famous for their rich milk. Some Illawarra, Guernsey, and Friesian cow genes were also added.
Why Mix Different Cows?
The scientists had clear goals for the new AMZ breed. They wanted cows that could handle heat well. They also needed cows that produced a lot of milk. Another important goal was for the cows to resist cattle ticks. Ticks are tiny bugs that can make cows sick. By mixing breeds, they created a cow that was strong and productive.
What Do AMZ Cattle Look Like?
AMZ cattle often look a lot like Jersey cows. They have similar colors, markings, and body shapes. However, you can also see traits from their Sahiwal and Red Sindhi ancestors. These include looser skin, which helps them stay cool in warm weather.
How Much Milk Do They Produce?
AMZ cows are good milk producers. Each cow can produce about 2,700 kilograms of milk during one lactation period. A lactation period is the time a cow produces milk after giving birth. This makes them a valuable breed for dairy farmers in warmer regions.
