CATTLE studs from NSW won all five interbreed classes at the National Beef Show at Bendigo on Sunday.

J&C Angus from Wildes Meadows won the show's supreme award for the Halliday family with a 15-month-old Angus bull.

The fifth National Show, which attracted nearly 800 cattle from 32 breeds, is now on a par with the Melbourne Royal Show beef entries.

But while NSW dominated the stud line-ups, Sutton Grange Belgian Blue breeder Max Davis's Belgian Blue-Murray Grey cross 12-month-old steer won the champion carcass from 125 cattle processed at Hardwick's Kyneton.

Committee president Richard Ham said there were record entries which not only filled the main exhibition centre but also had to be housed in a large marquee.

Organisers are hoping the record entry will add weight for government support for a second livestock pavilion at the Bendigo Showgrounds.
