Their should be a corn plant, you could find it growing wildly pick it and get 2 ears of corn and 2 corn seeds. You can plant the seeds like wheat, it would take the same amount of time as wheat. With corn you could just eat it, craft with bucket of water to make cornbread, or grind it into grain to feed to cows. By feeding them corn they will get a cow bell(like dog collar)and they will be yours. You can let them roam in a pasture and either kill them for meat or keep them for milk.
