It's always interesting to look inside the rare breeds tent and to talk to the people who are dedicated to helping these old strains of animals survive.
There are bound to be quite a number of sheep, cattle and ponies. And there could be goats and chickens - more details as the programme firms up.
Displays around the tent provide a lot of fascinating information. On Saturday there will also be a demonstration featuring many of our rare breeds in the sheep section judging rings.
The British Native and Traditional Rare Breed Sheep classes - this year generously supported by Cornwall Life, are also on show within the Rare Breeds Marquee.
