|Other||Mycoplasma||Attenuated tracheal and lung damage caused by Mycoplasma invasion. Can inhibit MG-triggered inflammation and apoptosis by suppressing the expression of MMP2/MMP9 through the JNK and p38 pathways and inhibit the expression of virulence genes to resist MG. Results suggest it might serve as one of the antibiotic alternatives to prevent MG infection.||Y Wang et al., 2022|
|Broilers||extract||0.4 g/L in drinking water||immunity||Improved body weight, weight gain, feed intake, and FCR. Licorice also exhibits a broad range of biological activities such as hypolipidemic, hypoglycemic, hepatoprotective, immunostimulant, and antioxidant effects. The morphometric analysis of different parameters of the intestine revealed a significant increase in the intestinal villi length, width, and villi length/crypt depth in the group supplemented with licorice 0.4 gm/L compared to other groups. The number of CD3 positive in both duodenum and ileum was increased in the licorice 0.4 gm/L group compared to other groups. The expression of growth-related genes was significantly increased with licorice supplementation and modulation of the lipid metabolism genes in the liver and upregulated to the mRNA expression of both superoxide dismutase (SOD1) and Catalase (CAT). Our results revealed that licorice supplementation increased the growth performance of broiler chickens and impacted the birds’ antioxidant activity through modulation of the growth-related genes, lipid metabolic markers, and antioxidant-related pathways||M Abo-Samaha et al., 2022|
