Dietary dried periphyton can improve growth, digestive enzyme, serum biochemical, antioxidant response and intestinal morphometric of Nile tilapia

The present trial was conducted to investigate the effect of inclusion dried periphyton in Nile tilapia diets on growth, digestive enzymes activity, haematological, oxidative stress and intestinal morphometric parameters. Five isoproteic (32%), isolipidic (5%) experimental were formulated, comprise graded levels (0, 2.5, 5, 7.5 10 g kg−1 diet). At end feeding trial, highest (P < 0.05) performance, feed utilization survival rate noticed fish fed diet contained diet. Also, amylase lipase activity markedly 0.5) higher Fish recorded value haemoglobin, haematocrit, red, white blood cells, neutrocyte, lymphocytes, monocytes eosinophil count. lowest level alanine aminotransferase, aspartate aminotransferase Alkaline phosphatas (AP) observed Serum total protein, albumin, globulin, phosphorus calcium ≤ However, content creatinine, cholesterol, triglycerides low-density lipoprotein-cholesterol noted 10. Higher values superoxide dismutase catalase compared with other treatments. malondialdehyde attained by current showed suitability as a dietary supplement its supplementation up 7 for improving enzyme, serum biochemical, antioxidant response tilapia.
