The study was carried out to investigate the effects of periodic administration of garlic extract drench on haematology and serum biochemistry of grazing lambs. Twelve West African dwarf sheep with an average weight of 12.00 ±0.77 kg were allotted to 3 treatment groups with 4 animals per group in a completely randomized design which lasted for 10 weeks. Treatment 1 (T1) served as control with no garlic extract, Treatment (T2) were given 5ml garlic extract weekly and Treatment T3 received 5ml garlic extract every 2 weeks. Results of haematological analysis showed that PCV significantly (P<0.05) differs among treatment groups while RBC, MCV, WBC, LYM and GRA all show no significant (P>0.05) difference. The lowest PCV of 19.68% was observed in T1 while T2 recorded the highest PCV of 29.68%. The results from serum biochemical indices shows that cholesterol and ALT differ significantly (P<0.05) among treatment groups while total protein, albumin, globulin, glucose, urea and AST all show no significant (P>0.05) difference among treatment means. The lowest serum cholesterol value of 0.78 was observed in T2 while the control group recorded the highest value of 1.30. The study suggests that garlic extract could be used to reduce the level of serum cholesterol in grazing lamb thereby improving meat quality.
