چکیده مقاله:
Moringa oleifera is an important herbal plant with a valuable source of major essential nutrients and nutraceuticals. In this study, we supplemented the diet of Litopenaeus vannamei with different levels of M. oleifera leaf powder (MLP) and extract (MLE) and evaluated the growth, survival, body and fatty acid composition, hemolymph biochemistry, antioxidant status, and salinity stress resistance after six weeks of feeding. In total, ۸۴۰ shrimp (۲.۶±۰.۰۲ g) were divided into seven groups including the shrimp fed with the basal diet (control), and the diets containing different levels of MLP [۲۵ (MLP۲۵), ۵۰ (MLP۵۰), and ۱۰۰ (MLP۱۰۰) g kg-۱] and MLE [۰.۲۵ (MLE۰.۲۵), ۰.۵ (MLE۰.۵), and ۱.۰ (MLE۱.۰) %]. The results showed a lower FCR value in MLP۲۵ and MLE۰.۵ fed shrimp as well as a higher survival rate in MLP۱۰۰ and MLE۰.۵ fed shrimp than those of the control group. Dietary MLP enhanced the body contents of lipid and fatty acids (i.e., the pentadecanoic acid and the omega-۳ and -۶ polyunsaturated fatty acids). The MLP۱۰۰ diet remarkably enhanced the hemolymph total protein, albumin, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels of shrimp. On the other hand, the AST and ALT activities were significantly reduced in the shrimp fed with MLP۲۵, MLE۰.۲۵ and MLE۰.۵ diets. MLP and MLE in the diet of shrimp also led to a significant increase in the hemolymph antioxidant enzymes activity. Moreover, the shrimp fed with MLP۵۰ diet showed a significantly higher survival rate in response to the high salinity stress compared to the control group. In conclusion, the supplementation of both MLP and MLE in the diet of L. vannamei showed beneficial effects on the performance of the shrimp farming industry.
