there is a product called relax fit, it's all natural. and it's a feed additive so they can't say you medicated them its not medicine, and it's not in a syringe or has a doctors label on it. it works amazingly. we get it at the feed mill. i think either kent or showmaster makes it, i can check for you. we use it on the craziest, witchiest cows ever and it calms em right down. you can feed it the whole time your at a show and actually i'd feed em the day before you load em on the trailer. its like 20 dollars for a container of it but it will take care of one animal for a few days. i use it on all my animals in smaller doses for the calm ones just to keep em calm in the ring. sometimes you still have to use show cattle calm that's still not a medication. medically calming them would be using ace or rompin, there is both powder and liquid form of ace, and rompin is liquid. we will use that at home if we have a crazy one to take the edge off at first, give a quarter cc of liquid on the gums. don't do more than that they will fall asleep.
