Considering the cost contribution of cattle feed to overall profit margins and the importance of vitamin supplementation as essential nutrients optimizing health and nutrition, vitamin stability is an important consideration to the nutritionist. Vitamins are skillfully formulated to optimize ease of use, safe handling, maintain potency for the desired duration of storage and to either disperse or solubilize and withstand specific pH ranges and temperature fluctuations. The vitamin formulation selected depends on the unique route of feed application, be it a viscous molasses-based feed supplement, or a dry feed application. This article explores the drivers of vitamin stability in cattle feed and details the different vitamin formulations available with a special focus on dispersible liquid feed concentrates.

With feeder cattle valued at an all time high, the health status of the receiving calf, now more than ever, affects feeder margins through its direct impact on morbidity and growth performance. Profitable finishing of feedlot cattle starts with the gestating cow, optimizing essential vitamin supplementation during all stages of the production cycle to deliver a robust calf at the yard with a nutritional baseline the feedlot nutritionist can build upon. In this review we delve into digestion and absorption of Vitamin A in cattle, with special emphasis on intestinal absorption and ruminal degradation rates, consider adequate supplementation guidelines to achieve optimal vitamin A status linked to specific health and performance outcomes, detail best indicators of vitamin A status and consider vitamin A supplementation options and their stability within the diet.
