WITH 500 extra racehorses to feed, local suppliers such as Pullens Produce store have been stretched to keep up with demand.
Store manager Brent Foley estimates the July Racing Carnival adds 300 bags of performance racehorse food to his inventory during race week.
Pullens Produce has had a long association with the carnival, dating from 1927 when the store first opened on Prince St.
Now located on Mary St, just 600m from the racetrack, Pullens Produce is an independent family owned business.
Owner Nicky Fletcher said she wished all customers the best of luck.
"We really appreciate the support we receive from the trainers that travel to Grafton for the carnival, it's great to see them come back to us each year," Mrs Fletcher said.
"It's also wonderful to see our local trainers and regular customers do well over the carnival."
