Many feedstuffs and forages do not provide the dietary vitamins necessary for optimum growth and development, making supplementation necessary. This volume offers a practical, well-organized guide to safe levels of vitamin supplementation in all major domestic species, including poultry, cattle, sheep, and fishes. Fourteen essential vitamins are discussed with information on requirements in various species, deficiency symptoms, metabolism, indications of hypervitaminosis, and safe dosages.
