This experiment was carried out to evaluate the effects of dried Phyllanthus amarus leaf meal (PLM) as an herbal feed additive on the growth performance, haematology and serum biochemistry of growing rabbits. Fifty (50) 8 weeks bucks cross breed rabbits (Chinchilla × New Zealand White) with an average weight of 505.5g and 508.7g were used. The five dietary treatments comprises of: treatment 1 containing basal diet as control, treatment 2 contained basal diet + 0.25g/kg, treatment 3, 4 and 5 were supplemented with PLM at 4%, 6% and 8% respectively. Clean feed and water were supplied ad libitum during the experiment which lasted for 90 days. The performance criteria covered final live weight, feed intake, feed conversion ratio, water intake and mortality. The final live weight, feed intake, feed conversion ratio and daily water intake were not (p>0.05) significantly different among the treatments. Results on haematology showed that PCV and Hb were the only parameters affected (p<0.05) by the dietary supplementation of OXY and PAM. Other serum biochemical parameters (Albumin, globulin, glucose, ALP, AST and ALT) were not significantly different (p>0.05). Mortality was recorded for rabbits in treatment 1 and 2 with three (3) rabbits each, none was recorded for animals in treatment 3, 4 and 5 respectively. The result of this study showed that PAM are rich in bioactive chemicals that have no negative effect on the general performance and health of rabbits and can be included up to 8% in the animals diet.
