Hazeldean's Jim Litchfield has praised his family, clients and Monaro agricultural community for their unwavering support during 160 years of seedstock operations.

The Litchfield family was joined by around 350 people to celebrate 160 years of Hazeldean seedstock at a wool and bull-themed party held on-property last week, following its spring bull sale.

Hazeldean is one of the oldest and largest merino and angus cattle studs in Australia. Six generations of Litchfields have built the Hazeldean empire.

At the celebrations, Mr Litchfield paid tribute to those who have contributed to Hazeldean's enduring success.

"The seedstock business is not a straightforward business. It's extremely detailed where at particular times of the year the workload is intense and other times it is very intense," Mr Litchfield said.

"It requires a certain sort of personality type to take up this job. And they are the ones who enjoy dealing with deadlines.

"Thank you to all who have bought bulls and rams and supported our philosophy and livestock breeding. We appreciate those who appreciate our ethos and the way we go about breeding and producing the bulls and rams we offer and the service we provide."

Mr Litchfield, his wife Libby, daughter Bea and her husband Ed Bradley run the Hazeldean operations. Mr Litchfield said he and Libby will look to move to their Myalla property in the coming years, and step back.

A special mention was made of the Monaro's Eccleston family, who has bought from Hazeldean since the late 1800s.
