Mechanistic Insights into the Physiological and Meat Quality Responses of Broiler Chickens Fed Incremental Turmeric Rhizome Meal

Le résumé fourni par la source

Natural products, such as turmeric rhizome meal (TRM), may hold the key to a sustainable solution to antimicrobial resistance rise and antibiotic prohibition in food-producing animals. This study evaluated the effects of dietary TRM at 0 (CON), 0.3 (TRM3), 0.6 (TRM6), and 0.9 g/kg (TRM9) on growth, nutrient digestibility, immunity, gut function, nutrient transport biomarkers, microbiome, and meat quality in 280 one-day-old male Ross 308 chicks over a 42-day feeding trial. Birds fed TRM indicated higher body weight gain and lower feed conversion ratio (p < 0.05). The TRM groups promoted higher (p = 0.001) serum immunoglobulin Y, immunoglobulin M, and interleukin-10 compared to the CON. Birds fed CON had higher interleukin-2 (p = 0.025), interleukin-6 (p = 0.027), and TNF-α (p = 0.008) levels compared to the TRM groups. Lactobacillus counts in jejunal villi and crypts were higher in the TRM groups than in the CON (p < 0.05). Dietary TRM increased electrogenic glucose and lysine transport, accompanied by up-regulation of claudin-5, zonula occludens 1, and mucin-2 expression (p < 0.05). In breast muscle, TRM fortification reduced malondialdehyde levels (p < 0.05) while increasing long-chain polyunsaturated fatty acids (p < 0.05). Thus, TRM is a potent, residue-free phytobiotic alternative to conventional antibiotic growth promoters in poultry systems.
