Abstract

In this study, the effects of different levels of garlic on performance and humoral immunity of broiler chicks were
investigated. Three hundred eighty four broiler chicks (Arian) from day one were divided into two groups of male and
female. Animals received four treatments diet including: 0.0% (control), 0.1% garlic Powder, 0.1% garlic tablet and 0.5%
garlic tablet from day 3 to 42 of age. A factorial design of 2 * 4 was applied for two sex and four treatment diets with four
replicates and 12 experimental units. Anti-SRBC titer for direct hem-agglutination assay and for the anti-Newcastle titer the
inhibitory hem-agglutination was used. At 42 days, chicks were slaughtered in order to weigh the bursa-fabricious (RF) and
spleen. The results of anti-SRBC titer, anti- Newcastle and weight of BF and spleen did not differ significantly when
compared to control group. However, feed intake, body weight and growth rate in 0.1 garlic powder in comparison with
garlic tablet showed an increasing trend. The results of immunity tests indicated that the levels of garlic used in this study had
insignificant effects on humeral immune parameters (p>0.05).
