Biological Mechanisms of the Aqueous Extract of (Alcea kurdic) on the Productive Performance and Microbial Content of the Intestines of Broiler Chickens

The main focus of this study to investigate the biological mechanisms by which a (Alcea kurdic) extract impacts chicken productivity and gut microbiome. A total of 225 chicks were randomly allotted to five treatments provided the first as a control (C-1), Levosav as antibiotics (Lo-2), with Aqueous Extract (AE) of Alcea kurdic (AK) at doses 5% (AE-1), 10% (AE-2), and 15% (AE-3) per on drinking water, each treatment contained 3 replicates (15 birds each replicates). The results clarified that there were a significant (p>0.05) changes in performance relative weight between different treatments. In contrast, there was a significant increase in the rate of body weight, body weight gain was observed across all treatments receiving the aqueous extract of hibiscus flowers compared to (C-1), and (Le-2) treatments. For the feed intake and feed conversion the treatments (C-1), and (Lo-2) showed significantly higher feed intake compared with the other treatments 5% (AE-1), 10% (AE-2), and 15% (AE-3). AE treatments had significantly feed conversion than the control (p<0.05). For the microbial population, intestinal total bacteria count was significantly lower in AE treatments compared with the control group (p<0.05), while there were changes in the lactobacilli count between different treatments. Moreover, E. coli were recorded lower in the AE treatments compared with the (C-1), and (Lo-2) treatments.
