β-胡萝卜素对种鸡繁殖性能和养殖经济效益的影响.

To support the growth of China's breeding chicken industry, many enterprises seek to enhance the safety and efficiency of chicken nutrition through advanced nutrition regulation technology. This is aimed at addressing issues such as low fertilization rates and slow weight gain among newborn chicks. One promising solution is β-carotene, a natural compound that is widely available and cost-effective. Once converted into vitamin A, β-carotene can provide vital nutrients for the body while offering valuable antioxidant and immune regulating properties. By reducing the harmful effects of free radicals, β -carotene can enhance animal health and disease resistance. This review explores the nutritional value and physiological benefits of β-carotene and recent research into its role in boosting the reproductive performance and economic benefits of breeding chickens.
