REVIEW: Potential Effects of Vitamins A and D on Marbling Deposition in Beef Cattle
|
Abstract
Seasonal variation in cattle grading Choice exists with percentages of carcasses grading higher in the spring and gradually declining throughout the summer with a low in October. Various nutritional or pharmacological agents have been shown to affect adipose conversion in vitro and in vivo. High (5 to 50 µM) levels of dietary fat-soluble vitamins, especially retinoic acid (RA) and 1,25-dihydroxyvitamin D^sub 3^ (D^sub 3^), inhibit adipocyte development, specifically bovine ma...
