Impact of Dietary Ginger and Ginseng Powder in Broiler Diet on the Physiological Traits and Immune Response of Avian Influenza

Abstract

The study aimed to investigate the synergistic effect of dietary ginger (Gn) and ginseng (Gs) powder
on performanceandevaluate the immune response to Avian Influenza(AI) vaccinein broilers. A total
of 160 unsexed broiler chicks (Ross 308) at one day- old were randomly divided to four equal groups
with two replicates. The chicks of the 1st group (control) were fed on a basal diet. The 2ndgroup fed
on a basal diet with adding Gn at (5gm/ kg feed). The 3rdgroup was fed on a basal diet with adding Gs
(5gm / kg feed). While the chicks of the 4thgroup were fed on a basal diet with adding Gn and Gsat
(2.5 gm/kg feed) of each. Immune response against AIwas measured at aged (5, 15, 25 and 35) days,
while hematological and biochemical tests were measuredat the end of the experiment. The results
showed significant differences (P ≤ 0.05) in 2ndgroup in the total protein and globulin concentrations as
compared to other groups and control at 35 days old. No significant differencein albumin concentration,
liver enzymes (ALT, AST). Also, the 2nd and 4th groups recorded a significant increase in WBC, RBC,
Hb and PCV%, as well as, the superiority in the Abagainst the AI at 35 days of age as compared to the
other groups. Finding of the current study indicated that groups which receiving dietary Gn and Gs
powder showed better health and higher Ab against AI disease vaccine
