ABSTRACT
This study investigates dietary fortification of heifer feeds with cholecalciferol and ergocalciferol sources and effects on beef total vitamin D activity, vitamer, respective 25-hydroxymetabolite contents, and meat quality. Thirty heifers were allocated to one of three dietary treatments [(1) basal dietâ¯+â¯4000â¯IU of vitamin D3 (Vit D3); (2) basal dietâ¯+â¯4000â¯IU of vitamin D2 (Vit D2); and (3) basal dietâ¯+â¯4000â¯IU of vitamin D2-enriched mushrooms (Mushroom D2)] for a 30â¯day pre-slaughter period. Supplementation of heifer diets with Vit D3 yielded higher (pâ¯<â¯0.001) Longissimus thoracis (LT) total vitamin D activity (by 38-56%; pâ¯<â¯0.05) and serum 25-OH-D concentration (by 20-36%; pâ¯<â¯0.05), compared to that from Vit D2 and Mushroom D2 supplemented animals. Irrespective of vitamin D source, carcass characteristics, sensory and meat quality parameter were unaffected (pâ¯>â¯0.05) by the dietary treatments. In conclusion, vitamin D3 biofortification of cattle diets is the most efficacious way to enhance total beef vitamin D activity.
