The effect of late gestation injectable vitamin A and D supplementation on sow and piglet performance.

ABSTRACT: Vitamin A is an essential nutrient with an important role in animal health across livestock species. Insufficient dietary vitamin A intake is associated with decreased reproductive performance in females as well as impaired growth performance and health of the offspring. The aim of this study was to determine if an intramuscular injection of vitamin A and D (VitAD) given to sows on d 85 of gestation improved the survivability, growth performance, and health of the offspring from birth through the end of the nursery phase. Yorkshire or Yorkshire cross bred sows received either an injection of VitAD (312,000 IU vitamin A, 52,500 IU vitamin D. n = 9) or saline control (n = 10). At farrowing, birth weights, survival, and umbilical blood was collected on the piglets, and colostrum
