An accurate understanding of properties of probiotics is a prerequisite for selecting probiotic organisms for use in swine production. This review aims to review selection criteria for probiotic organism in swine. The systematically investigated ecological history rather than the source of isolates should be regarded as the natural origin of probiotic strains, which helps to correct the inconsistencies arising from incorrect identification of the source. Moreover, in vivo studies are suggested as follow-up assessment to validate the characteristics of probiotic predicted by in vitro experiments. In addition, the intended probiotic effect depends on the age of the animal and disease prevention in young animals may require different probiotic strains when compared to growth promotion in older animals. With adequate selection criteria, the inclusion of probiotic in feed supplementation is a promising way to exert positive effects on sows, newborns, weanling animals and grower-finisher pigs. Both host-adapted probiotics and nomadic probiotics can be applied for pathogen inhibition but host adapted organisms appear to have a different mode of action. Host-adapted probiotic strains are likely to be associated with exclusive colonization while the nomadic or environmental strain exert better immune stimulating functions. Strains with potent enzymatic activity are fitter for grower pigs favoring feed digestion and enhancing growth performance.

正确认识益生菌的性质是选择用于猪生产的益生菌的前提。这篇综述旨在综述猪中益生菌的选择标准。经过系统调查的生态史而不是分离物的来源应被视为益生菌菌株的自然起源，这有助于纠正由于错误识别来源而引起的不一致之处。此外，建议进行体内研究作为后续评估，以验证体外预测的益生菌的特性实验。另外，预期的益生菌作用取决于动物的年龄，与年长动物的生长促进相比，年轻动物的疾病预防可能需要不同的益生菌菌株。通过适当的选择标准，在饲料中添加益生菌是一种对母猪，新生儿，断奶动物和成年肥育猪产生积极影响的有前途的方法。宿主适应性益生菌和游牧性益生菌均可用于病原体抑制，但宿主适应性生物似乎具有不同的作用方式。适应宿主的益生菌菌株可能与排他定居有关，而游牧或环境菌株则发挥更好的免疫刺激功能。
