Any time, really, if you are referring to a cow as a mature female bovine that has at least two calves. Most cows that are entered in a show should be entered when their calves are at least 2 or 3 months of age. She and her calf can be entered in a mix breed class or, if her and her calf are purebreds, in a specific breed class.
If you are referring to a "cow" as anything but what was mentioned above, heifers can be entered when they are yearlings, steers when they are around 18 months of age, and bulls when they are yearlings and older.
Show rules and regulations depend on what show you are entering and where you live.
While it's true there are no official rules about the horse's age in show jumping, most of the higher level jumpers are older, experienced horses because of the amount of training and physical development needed to handle the demands of the sport.
Horses usually (varies with breed) don't fully develop until the age of 5 or later so starting a horse over fences before that is discouraged. But because of the peak performance of the horse being around 11 or 12 years old, few trainers wait that long. After the age of 12, the horses generally start to lose their ability to keep up with the highest level of athleticism.
At the lower levels, you will see every age of show jumper, from 5 years old to 25 years old.
All shows age requirements differ. Check with the staff of the show you wish to enter.
I have seen 5 year olds do aaaall kinds of things.
