The use of synthetic and natural vitamin D sources in pig diets to improve meat quality and vitamin D content
2018
Abstract This study investigated the effects of synthetic and natural sources of vitamin D biofortification in pig diets on pork vitamin D activity and pork quality. One hundred and twenty pigs (60 male, 60 female) were assigned to one of four dietary treatments for a 55 d feeding period. The dietary treatments were (1)50 μg vitamin D₃/kg of feed; (2)50 μg of 25-hydroxvitamin D₃/kg of feed (25-OH-D₃); (3)50 μg vitamin D₂/kg of feed; (4)50 μg vitamin D₂-enriched mushrooms/kg of feed (Mushroom D₂). The pigs offered the 25-OH-D₃ diet exhibited the highest (P Longissimus thoracis (LT) total vitamin D activity. Mushroom D 2 and 25-OH-D 3 supplementation increased pork antioxidant status. The vitamin D₂-enriched mushrooms improved (P 2 may be a new avenue to improve animal performance and pork quality.
