| Abstract |
| The aim of this research was to evaluate the effects of zinc-enriched yeast on immune and biochemical factors of mucus and blood serum in common carp (Cyprinus carpio). This research in the form of a completely randomized design with 3 treatments and 3 replications including 1- basic diet (control treatment), 2-diet containing Candida utilis with 0.67 g/kg of food (non-enriched probiotic), 3- diet containing Candida utilis enriched with zinc at the rate of 0.67 g/kg food (enriched probiotic) was carried out for 60 days. 300fish with an average weight of 12 ± 0.33 grams were randomly distributed in 300-liter tanks with a density of 25 fish in each tank. Based on the results, in terms of blood serum immune factors, the highest level of ACH50, lysozyme activity and total immunoglobulin was significantly obtained in the enriched yeast and the lowest in the control treatment (p<0.05). In terms of the biochemical factor of serum and mucus, the highest amount of total serum protein was significantly in the enriched probiotic and the lowest in the control treatment, and the highest amount of total mucus protein in the un-enriched probiotic treatment and the lowest in the control treatment (p<0.05). Based on the results of the present research, the use of zinc-enriched yeast in the diet has a significant effect on the immune system. Therefore, including the suggested zinc levels in the diet can help to strengthen and improve the immune system of the target species against all types of stress and unfavorable environmental conditions. |
