Abstract

Garlic has been shown to have several effects in the body including its role in diabetes, blood coagulation, metabolism and immune functions. But there are scanty reports regarding its effect on haematological parameters in poultry. The study was conducted on 24 broiler chicks divided randomly into 3 groups, each group consisting of 8 birds. Group I birds were used as control kept on conventional diet. Group II and III birds were supplemented with garlic at the rate of 1.5% and 3.0% respectively (on dry matter basis) of total feed for a period of 8 weeks. Haematological parameters like heamoglobin (Hb), total erythrocyte count (TEC), total leucocyte count (TLC) and differential leucocyte count (DLC) were studied. Values of Hb and TEC were found to be insignificantly lower in garlic treated groups till the end of the experiment. These effects may probably be due to the presence of some hemolytic bioactive constituents and/or their metabolites in garlic. Slight rise in lymphocyte and heterophil counts were observed in garlic supplemented groups which may be due to immuno-stimulatory effects of garlic. In conclusion, haematological parameters are not significantly affected by garlic supplementation in feed and slight variation in DLC may be due to the interaction of garlic with immune system and Hb and TEC variations may be due to hemolytic constituents of the garlic.
