Effect of dietary lecithin on antioxidant defense of rainbow trout, Oncorhynchus mykiss broodstock and offspring
Introduction: Soybean lecithin (SBL) is usually added to aquafeed as a phospholipids source because aquatic animals including crustaceans and fish cannot synthesize phospholipids. Hence, this study aimed to evaluate the effects of different levels of dietary soybean lecithin (a source of phospholipi...

| description | Introduction: Soybean lecithin (SBL) is usually added to aquafeed as a phospholipids source because aquatic animals including crustaceans and fish cannot synthesize phospholipids. Hence, this study aimed to evaluate the effects of different levels of dietary soybean lecithin (a source of phospholipid) on the antioxidant defense system of female and male broodstock, ovum, eggs and the first stage swimming larvae of rainbow trout, Oncorhynchus mykiss.
Materials and methods: For this purpose, fish were fed four isoproteic and isolipidic diets containing graded levels of soybean lecithin (SBL) as a source of phospholipid (including 0, 2, 4 and 6%) for 190 days. At the end of the experiment, the samples of serum, ovum, egg and larvae were collected for antioxidant activity of CAT, SOD and MDA analyses.
Results and discussion: The results obtained showed that 4-6% dietary SBL supplementation significantly increased the antioxidant enzymes activity, including catalase and superoxide dismutase in the fish blood serum, eggs, and larvae compared to the control. On the other hand, MDA level in the control group was higher than in the other treatments (p<0.05). Thus, considering the data on improved the activity of antioxidant enzymes, it is recommended to include SBL at 4-6% in rainbow trout broodstock diet.
Conclusion: It is concluded that an optimal lecithin content in the diet of rainbow trout broodstock can lead to improving quality of ova and larval immune system.
Funding: This work was supported by the Office of Vice-Chancellor for Research and the Artemia and Aquaculture Research Institute of Urmia University in the framework of the postdoctoral research of Dr. Fatemeh Jafari (grant number 98/A/007). |
