Abstract
Abstract This study was conducted to determine the effect of the use of an aqueous extract of myrtle leaf boiled in some immunological and microbiological traits of broiler chicks. Atotal of 240 chicks, one day old of Ross 308 broiler chickens were randomly distributed into four treatments by 60 chicks per treatment with three replicates (20 chicks per replicate) and reared 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. 4. The fourth treatment: Add aqueous extract of myrtle leaf at 300 ml /liter of drinking water. The results showed the following: 1. A significant increase in (p≤0.05) cellular immunity and volumetric antibodies against Newcastle virus (ELISA) as well as in the relative weight of the fabricia gland and Bursa Index in birds drink water with aqueous extract of myrtle leaves in comparison with control treatment. 2. Treatment caused a significant decrease (p≤0.05) in logarithmic number of aerobic and Coliformis bacteria, with a significant increase (p≤0.05) in logarithmic Lactobacillus bacteria in duodenal of the small intestine.
