Abstract
This experiment was conducted at the Poultry Farm of the Faculty of Agriculture, University of Al-Qasim Green during the period from 18/9/2019 to 23/10/2019. The study aimed to study the effect of adding different levels of lemongrass leaves (Cymbopogon citratus) to the diet or its extract to drinking water on microbial content the gut of broiler chickens (Ross 308). 225 unsexed broiler chicks (Ross), which obtained from Al-Anwar hatchery, were randomly distributed on 15 pen, with 5 experimental treatments, and 45 birds for each treatment. Each treatment included three replicates per 15 birds. The treatments of the experiment were as follows: First treatment: control group free from any addition. The second treatment: a basic feed added to 10 g of lemon grass/kg feed, the third treatment: a basic feed added with 20 g of lemon grass/kg feed, the fourth treatment: adding 100 ml of the aqueous extract of the lemongrass/liter of drinking water, and the fifth treatment: adding 200 ml of the aqueous extract of the lemongrass liter of drinking water. The experiment included studying the following characteristics: The number of total aerobic bacteria, colon bacteria and lactobacilli. 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 as well as in cecum in the addition treatments (second, third, fourth and fifth) compared to the first treatment (control).
Key words: Lemon grass, Cymbopogon citratus, Broiler chicken, Microbial content, Gut of broiler.
