The effects of synthetic and natural beta-carotene as well as vitamins A and E supplementation on the fertility of sows and number of piglets in a litter were the subject of our studies. The sows fed beta-carotene had from 2 to 4 more piglets in a litter. Vitamin E had a harmful influence on beta-carotene action. It was found that synthetic beta-carotene and vitamin A increased the number of viable embryos and yellow bodies in the sows slaughtered on the 28th day of gestation, moreover beta-carotene subsequently improved the fertility of sows in the next reproductive cycle.
合成β-胡萝卜素、天然β-胡萝卜素以及维生素A和维生素E的补充对母猪繁殖力和窝产仔猪数的影响是我们研究的主题。饲喂β-胡萝卜素的母猪窝产仔猪数多2至4头。维生素E对β-胡萝卜素的作用有不良影响。研究发现，合成β-胡萝卜素和维生素A增加了在妊娠第28天屠宰的母猪体内存活胚胎和黄体的数量，此外，β-胡萝卜素随后还提高了母猪在下一个繁殖周期的繁殖力。
