This paper presents the results of investigations carried out in studying the relationship between the different
levels Glycyrrhiza glabra extract and growth performance in male quail. A total of 300 one-day old unsexed male
quail birds were used in the experiment. Birds were randomly distributed into 5 groups of 60 birds each, in 4
replicates containing 15 birds each. Five experimental diets (0, 0.5, 1, 1/5 and 2 g/kg) were fed between 1 and 42
days of age. Results showed that the addition of Glycyrrhiza glabra did significantly influence quail body weight
and feed intake during both the starter (1-21 days) and grower (21-42) periods of the study (p <0.05), but did not
there was not any significant effect on feed conservations ratio during the experiment (P>0.05). In general,
Glycyrrhiza glabra stimulated growth rate and feed efficiency of quail when included in certain types of poultry
