Significant numbers are expected again from Central Hawke's Bay breeder Tony Thompson, of Glenanthony Simmentals, who claimed the show's Meat and Wool Cup last year, as he had when the section had last previously been run at Dannevirke in 2000.
The cattle classes now pose a viable option for breeders looking at the Royal Show in Hastings in October.
They are expected to attract a number of entries across the central North Island from Hawke's Bay to Taranaki, including Manawatu and the Horowhenua area.
The show also has strong sheep entries, and increasing entries for equestrian events, which dominate the last day of the show.
A big feature of the opening Friday is the Dannevirke Shearing and Woolhandling Championship and Aotea Rugby Club speedshear.
The event is in the busiest stage of the shearing sports season, which has competitions at the Taihape and Rotorua shows this weekend, and events at Marton and Aria in King Country clashing on Waitangi Day.
As part of the speedshear, the rugby club is trying to attract teams from other clubs for a feature event which has been held each year since the club first staged the speedshear in 2011.
A and P Show president Brian Beale said the event, on its own 17ha site, was in a good financial position and thriving from year to year.
