Concerns over animal welfare continue to be a critical component of law and policies associated with commercial food animal production. Social and market pressures are the driving forces behind the legislation and result in the change of poultry production management systems. As a result, the movement toward cage-free and aviary-based egg production systems has become standard practices. Cage-based systems being replaced by alternative methods that offer a suitable housing environment to meet or exceed poultry welfare needs and require different management, including the ban of antibiotics in poultry diets. For broiler production, pasture- raised and free-range management systems have become more popular. However, challenges remain from exposure to disease-causing organisms and foodborne pathogens in these environments. Consequently, probiotics can be supplemented in poultry diets as commercial feed additives. The present review discusses the impacts of these probiotics on the performance of alternative poultry production systems for improving food safety and poultry health by mitigating pathogenic organisms and improving egg and meat quality and production.
动物福利问题一直是与商业食品动物生产相关的法律和政策的一个关键组成部分。社会和市场压力是立法的驱动力，导致家禽生产管理系统发生变化。因此，无笼和笼养蛋鸡生产系统已经成为标准做法。笼养系统正被其他方法所取代，这些方法为满足或超过家禽福利需求提供了合适的饲养环境，并且需要不同的管理方法，包括在禽饲料中禁止使用抗生素。对于肉鸡生产，放牧和散养管理系统变得越来越受欢迎。然而，这些环境中仍然存在接触致病生物体和食源性病原体的挑战。因此，益生菌可以作为商业饲料添加剂添加到家禽饲料中。本综述讨论了这些益生菌对替代家禽生产系统性能的影响，通过减轻病原生物体和改善鸡蛋和肉类质量和产量，从而提高食品安全和家禽健康。
