An evaluation of modulatory impacts of dietary zeaxanthin supplementation on Macrobrachium nipponense: Growth, hematological, immunological, and physio-metabolic responses
An eight-week study assessed the effects of zeaxanthin supplementation on growth metrics, biochemical indices, non-specific immune responses, and metabolic changes in Macrobrachium nipponense. Five dietary treatments were given to prawns averaging 1.39 ± 0.05 g, with zeaxanthin concentrations of 0 (...

| description | An eight-week study assessed the effects of zeaxanthin supplementation on growth metrics, biochemical indices, non-specific immune responses, and metabolic changes in Macrobrachium nipponense. Five dietary treatments were given to prawns averaging 1.39 ± 0.05 g, with zeaxanthin concentrations of 0 (control), 50, 100, 150, and 200 mg/kg. Findings demonstrated that growth were markedly influenced by zeaxanthin levels (P < 0.05), with the exception of the hepatosomatic index (HSI), which did not show significant variation (P > 0.05). The majority of hemato-biochemical indexes exhibited a significant decrease (P < 0.05), while levels of high-density lipoprotein (HDL) and low-density lipoprotein (LDL) demonstrated a substantial increase in comparison to the control group (P < 0.05). Conversely, the concentrations of calcium, phosphorus, and cholesterol did not reveal any statistically significant differences (P > 0.05). Indices related to innate immunity and antioxidative status changed notably after zeaxanthin treatment (P < 0.05), but the levels of glutathione peroxidase (GPx) and alkaline phosphatase (AKP) remained unchanged (P > 0.05). Supplementation with 200 mg/kg of zeaxanthin improved digestive enzyme activities, intestinal microflora, total carotenoid content (TCC), and carcass composition (P < 0.05). Gene expression related to growth, immunity, and metabolism was also affected (P < 0.05). Prawns receiving zeaxanthin exhibited improvements in amino acid and fatty acid profiles, with marked increases in essential amino acids (EAA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA) (P < 0.05). Collectively, this study suggests that 200 mg/kg of zeaxanthin enhances growth, immunity, and various physiological functions in oriental river prawn. |
