The effect of dietary retinoic acid (RA) on the growth, lipid deposition, oxidation resistance, immunity, hepatopancreatic and intestinal health Macrobrachium rosenbergii was evaluated. A total 1200 prawns (0.22 ± 0.00 g) were divided into six groups fed their corresponding feed containing 4, 132, 296, 562, 1206 or 2562 mg/kg RA. weight gain rate, specific growth rate final body changed linearly quadratically, with maximum observed in those 296 Increasing RA quadratically raised content whole body. Compared to 4 RA, there significantly lower deposition muscle, hepatopancreas Prawns had triglyceride (TG) upregulated gene expression retinoid X receptor ( RXR ), diacylglycerol acyltransferase 1 dgat1 ) carnitine palmitoyltransferase cpt1 ). Additionally, increased protein RXR, CAMKKβ phospho-AMPK. level could decrease oxidative stress by upregulating peroxiredoxin 5 prx5 improve immunity toll - like 2 toll2 myeloid differentiation factor 88 (myd88 dosal hepatopancreas. related genes crustin / 3 , anti-lipopolysaccharide 7 peritrophin-1 myosin light chain kinase claudin myd88 morphological structure also positively affected Furthermore, relieve immune responses induced lipopolysaccharide, thus leading transcription antimicrobial peptides. In summary, utilisation, antioxidant capacity M . To avoid negative effects excessive addition obtain optimal a diet suggested present study.
