Effect of different levels of dietary acidifier “sodium diformate” on the innate immune system and expression of growth and immunological related genes in Salmo trutta caspius

Sodium diformate (SDF) is an organic acid that modulates growth performance, health and immunological properties. However, nowadays there is limited information available about the effects of SDF on innate immune system, growth performance and immune‐related gene expression. Due to the lack of information about this supplement, this study aimed to evaluate the effect of SDF on the innate immune system, growth and immune‐related gene expression. Salmo trutta caspius fed control or diet supplemented with different levels (0.5, 1 and 1.5 g/Kg) of SDF for 8 weeks. The results showed that T3 improved significantly (p
