Effects of dietary procell alone and in combination with Lactobacillus plantarum and Lactobacillus pentosus on serum biochemical parameters and some oxidative enzymes of rainbow trout (Oncorhynchus mykiss)

Intensive and commercial aquaculture need to improve the fish welfare and probiotics are considered as a suitable candidate to achieve this goal. In this study, the effect of procell synbiotic supplement is evaluated as alone and in combination with endogenous bacteria on biochemical parameters and some oxidative enzymes in rainbow trout serum. For this purpose, 300 rainbow trout fingerlings with average weight of 15g were randomly divided into five groups with three replicates, which were fed for 12 weeks with normal diet and without any additives (control), procell synbiotic at 1%, procell synbiotic 1% and Lactobacillus plantarum at 108CFU/mg, procell symbiotic 1% and Lactobacillus pentosus at 108CFU/mg and procell synbiotic 1% and L. plantarum and L. pentosus at 108CFU/mg, respectively. Sampling was performed on days 0 and 60. The results showed that the use of diets containing procell+L. plantarum+L. pentosus is able to improve the biochemical, antioxidant and liver enzymes in rainbow trout fingerling serum.
