Impact Of Avocado (Persea Americana) Seed Meal On The Liver And Kidney Of Oreochromis Mossambicus At Different Diet Concentrations

A study to investigate the impact of avocado (Persea americana) seed meal on the liver and kidney of 150 Oreochromis mossambicus at different diet concentrations was carried out.The fishes were randomly assigned to 5 treatment group, with each group having 3 replicate per group for 155 days.The objective of this study is to investigate the functionality, chemical composition of the seed and to established its suitability of use as food ingredient and for medicinal purposes.Proximate analysis of P. americana revealed mean dry weight as 4.39, CHO -13.97,Moisture -71.12 and Fibre -6.93.AST in 10% treatment group (89 0) was significantly higher than the control group 75 14 (P<0.05)ALT in treatment groups 5%, 10%, 15%, and 20% were relatively consistent ranging from 32.67 6.39 to 36.33 3.33 UL.ALP had a downward consistent trend as the proportion of P. americana seed increased (29 8.08ab, 28 3.79ab, 17 3.06b, 15 1.53b) groups 5%, 10%, 15% and 20% respectively.There was a downward but non consistent trend in the Albumin value ranging from 77.6710.2 a for the control group to 273.51 b with the 15% group having the least value.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.Similarly, the chloride level ranged from 118.00 to 121.33 mmol/L, experiencing a downward consistent trend from the control group (121.33) to the 20% diet group (118.00).Potassium showed an upward but inconsistent trend ranging from 8.70 mmol/L for the control group to 9.57 mmol/L for the 20% diet group.It is therefore concluded that Avocado seed meal is a safe feed additive for fish feed.
