This study was conducted to determine the effect of the use of an aqueous extract of myrtle leaf boiled in some histological and morphological traits of broiler chicks. A total of 240 chicks one day old Ross 308 broiler chickens. Chicks were randomly distributed to four treatments by 60 chicks per treatment with three replicates (20 chicks per replicate) were rearing in the batteries containing the cage dimensions of 1.5 × 1.0 m. The treatments were as follows: 1. The first treatment (control treatment without any addition), 2. The second treatment: Add aqueous extract of myrtle leaf at 100 ml /liter of drinking water, 3. Third treatment: Add aqueous extract of myrtle leaf at 200 ml /liter of drinking water, and 4. The fourth treatment: Add aqueous extract of myrtle leaf at 300 ml /liter of drinking water. The results showed that treatments cased significant improvements, as compared to control p≤0.05 in weight and the relative length in duodenal, jejunum, ileum and scum. Significant increases were recorded (p≤0.05)in the length of villi and depth of the crypts of bird populations in aqueous extract of myrtle leaves treatments in comparison with control.
