Impacts of Solid-State Fermented Barley with Fibrolytic Exogenous Enzymes on Feed Utilization, and Antioxidant Status of Broiler Chickens

The present and future high demand of common cereals as corn wheat encourage the development feed processing technology that allows for dietary inclusion other low nutritional value in poultry feeding. Barley grains contain anti-nutritional factors limit their industry. treatment barley with solid-state fermentation exogenous enzymes (FBEs) provides a good alternative to cereals. In this study, were subjected microbial using Lactobacillus plantarum, Bacillus subtilis fibrolytic enzymes. This study aimed assess impact FBEs on growth, utilization efficiency, immune modulation, antioxidant status expression intestinal barrier nutrient transporter-related genes. One-day-old broiler chicks (Ross 308, n = 400) comprised four representative groups ten replicates (10 chicks/replicate) fed corn-soybean meal basal diets inclusions at 0, 5, 10 15% 38 days. Solid-state increased protein content, lowered crude fiber reduced sugars compared non-fermented gains. consequence, group FBEs10% had superior efficiency body weight gain (increased by 4.7%) higher levels metabolizability, pancreatic digestive enzyme activities digesta viscosity. Notably, showed an villi height decreased crypt depth remarkable hyperactivity duodenal glands. addition, boosted serum immune-related parameters breast muscle antioxidants status. Intestinal transporters encoding genes (GLUT-1, CAAT-1, LAT1 PepT-1) barriers (MUC-2, JAM-2, occludin, claudins-1 β-defensin 1) upregulated levels. conclusion, feeding positively enhanced chickens’ performance, status,
