ABSTRACT

An 8 weeks feeding trial of different percentage inclusion of Thevetia peruviana seed meal in the diet of Clarias gariepinus was conducted. The experimental diets were Ctr0TSM, 5TSM, 10TSM 15TSM and 20TSM percentage replacement of plant protein in the control diet. The experimental design is a complete randomize design in which there were three replicates for each of the treatment. And the fish were stocked 10 per each tank, fed experimental diet two times a day of 5% body weight over eight weeks. Growth performance haematology and tissue composition were measured to assess diet effects. At the end of the study, there was significant difference (p<0.05) between the weight gained, average daily weight gained, feed intake, FCR, PER, FER, SGR, of fish fed percentage inclusion of Thevetia peruviana seed meal to the control experimental diet, with better growth values recorded in fish fed 20TSM Thevetia peruviana seed meal inclusion, however a bit high percentage of mortality was recorded as increase in the percentage. inclusion but low mortality in 20% inclusion of the oleander seed meal, similarly in. the haematological parameters there were significant difference (p< 0.05) also in the values recorded in white blood cell, packed cell volume, red blood cell, hemoglobin concentration and MCH, but similarities (p>0.05) occurred in the neutrophil, lymphocyte, MCV and MCHC of haematological parameters of fish fed the experimental diets. The inclusion of Oleander seed meal up to 20% in the diets of Clarias gariepinus, had a positive effect on growth and haematology of the fish.
