Trikes are the most useful creatures at lower levels/starting out. Easy and simple tames. The saddle isn't to hard to create. The many resources you can get ESPECIALLY berries can help you out in the long run.
They are easy first get slow level if you are start game. Preferably a lvl1 to a lvl 10. Then knock it out with a slingshot or tranqs. I run in circles and knock it out. After that let starve for 3-5 minutes then feed green kibble ,crops , or mejos. After that give either narco berries or narcotics. Then you got a trike.
