摘要
非抗生素饲料添加剂有助于提高猪的免疫系统,并降低断奶和其他环境应激带来的负面影响。最常用的饲料添加剂包括酸化剂、锌铜、益生菌、直接饲喂微生物、酵母类产品、核苷酸和植物提取物。研究表明添加药理水平的锌铜、特定酸化剂和部分植物提取物可以改善猪的性能或提高其免疫功能。使用益生菌、直接饲喂微生物、酵母类产品、核苷酸也有可能对猪的性能产生有利影响,但因研究结果缺乏一致性,因此仍需进一步研究。
A number of feed additives are marketed to assist in boosting the pigs＇ immune system and reduce the negative impact of weaning and other environmental challenges.The most commonly used feed additives include acidifi ers,zinc and copper,pre-biotics,direct fed microbials,yeast products,nucleotides,and plant extracts.Inclusion of pharmacological levels of zinc and copper,certain acidifi ers,and several plant extracts have been demonstrated to result in improved pig performance or improved immune function of pigs.It is also possible that use of pre-biotics,direct fed microbials,yeast,and nucleotides may have positive impacts on pig performance,but results have been less consistent and there is a need for more research in this area.
