Abstract:

The present investigation was conducted to determine the impact of the dietary addition of garlic and ginger as natural feed additives on feed intake, productive performance, carcass characteristics, hematology and serum biochemistry, economic efficiency, and mortality of broilers. A total of one hundred and ninety-two day old, unsexed (cobb-500) broiler were randomly divided into four experimental groups with three replication per treatment which consisted 16 birds. The birds were fed on two control diets (starter and finisher diets). The garlic (Allium sativum) and ginger (Zingiber officinale) were added in levels to the experimental diets in the four experimental groups. The first group (T1) fed on diets without feed additives (control diet). The other groups (T2), (T3) and (T4) were fed on basal diets supplemented with levels of 0.5% garlic, 0.5% ginger and 0.5% and 0.5% ginger mixture, respectively. The results showed that, the diet with T4 had significantly (P
