Effects Of Avocado (Persea Americana) Seed Meal On Hematological Parameters And Liver Enzymes Of Mozambique Tilapia (Oreochromis Mossambicus)

Effects of avocado (P.americana) seed meal on hematological parameters and lipid profile of Mozambique tilapia was studied.150Mozambique Tilapia were used for the experiment.They were divided into five groups of 30 fish per group.Each group was treated with different levels of Avocado seed meal inclusion in their diet.Groups1,2,3,4, and 5 were included as 0% 5% 10%, 15%, and 20% respectively for 155 days.Result indicate that the treatment did not cause any significant difference (p>0.05) in the hematological parameters.However, the red blood cell (RBC) and white blood cell (WBC) and monocytes had substantial increase.while the platelet, mean Corpuscular hemoglobin concentration (MCH) mean corpuscular volume eosinophils were reduced though not statistically significant.leucocytes and.The liver enzyme test result showed that ALP was significantly lowered by the treatment from a value of 38.008.09 to a value of 151.53 in the group 5.While TP significantly decrease from 67.67127 in group 1 to 243.46 in group 5. other liver enzyme parameters were not significantly affected by the treatment.It is therefore concluded that Avocado seed meal is a safe feed additive for fish feed.
