Abstract
The effect of varied levels of inclusion of Garcinia
kola seed meal in diets on growth performance and
haematological parameters was investigated in
Clarias gariepinus fingerlings. Fish were fed diet
supplemented at 0, 50, 100, 150 and 200 g kg-1
inclusion levels of Garcinia kola seed meal for eight
weeks. Fish feed supplemented with Garcinia kola
meal showed significantly improved growth
performance and feed utilization over the control
(0 kg-1 Garcinia kola seed meal) treatment. The
highest specific growth rate (1.34±0.02% day-1) and
best feed conversion ratio (16.28±0.05) were obtained
in 100 g kg-1inclusion level of Garcinia kola
seed. Protein efficiency ratio and feed conversion
efficiency were also higher in fish fed with Garcinia
kola seed meal and lowest in the control. Generally
growth decreased beyond 100 g kg-1 level of
inclusion. Protein and lipid content increased
(p<0.05) in fish supplemented with seed meal. Also
there was an improvement in blood parameters
(WBC, HGB, RBC, and PCV) in fish fed with
Garcinia seed meal compared to the control. The
result suggests that dietary supplementation with
Garcinia kola seed meal improved growth rate and
feed utilization was the best at 100 g kg-1 for Clarias
gariepinus fingerlings.
