The major vitamin requirement is for vitamin A. Vitamin A can be provided in the feed or by injection. However, in show steers it is probably preferred to feed vitamins rather than injecting vitamins. Using high quality feeds can reduce some of the concern about the other vitamins. A commercial protein supplement, fortified with vitamins, can reduce the chances of a deficiency. Yeast products can be a good source of B vitamins.
B vitamins can be useful during times of stress.
Feed at least 4-5 pounds of hay daily. Feeding high quality alfalfa may promote diarrhea. A good quality grass hay will be a better choice or blend 2 pounds of alfalfa with 2 to 3 pounds of grass hay. Wheat bran or dried beet pulp are good feeds for adding bulk to a diet. If a large belly is a problem, reduce the bulk in the diet.
