Abstract

This study aimed to investigate the effect of adding different concentrations of licorice extract to drinking water in improving the productive performance of broilers, where 180 unsexed Ross-308 broilers were used at one day old, then the chicks were randomly distributed into 4 treatments that included each treatment of 3 replicates, 15 chicks for each replicate, and the rearing period was from one day age to 42 days age. The treatments included in the current study were: the first treatment T1, control (without adding), the second treatment (T2), the third treatment (T3), and the fourth treatment (T4), which included the addition of licorice extract in percentage (1.5,1,0.5)%.The results of the study indicated that treatment with licorice extract led to a significant increase (P<0.05) in live body weight, weekly and cumulative weight gain, main cuts (breast and thigh), and a significant decrease (P<0.05) in weekly and total feed consumption and Weekly and cumulative food conversion ratio, and there were no significant differences between all treatments with regard to secondary cuts (wing, neck and back) and some edible internal organs (liver, heart and gizzard). The results for all of these traits were in the third treatment (1%), followed by the fourth treatment (1.5%). We conclude from this that the birds that took water with licorice extract gave better production performance than those that were not fed with the extract.
