EFFECT OF TURMERIC RHIZOME MEAL AS A NATURAL BIOTECH ADDITIVE IN FINISHER BROILERS' DIETS
Abstract
In pursuit of sustainable livestock solutions for Nigeria’s poultry sector, this study evaluated turmeric rhizome meal (TRM), a phytogenic biotech alternative, as a feed additive for enhancing broiler health and productivity. A 28-day trial assigned 144 Ross 308 broilers to four diets: 0.00% (T₁), 0.30% (T₂), 0.60% (T₃), and 0.90% (T₄) TRM. Performance, haematological, and serum biochemical parameters were analysed. Results indicated that T₃ maximised physiological benefits without compromising growth: body weight gain (2,068g) and feed conversion ratio (2.05) aligned with controls (p > 0.05), while blood indices (haemoglobin, lymphocytes) improved significantly (p < 0.05). Critically, TRM reduced serum cholesterol (3.66 mmol/L) and enhanced protein metabolism, specifically globulin levels (43.01 g/dL), confirming its role in optimising nutrient utilisation. Turmeric’s bioactive compounds (curcuminoids, terpenoids) demonstrate potential as natural biotech tools for replacing synthetic additives and supporting antibiotic-free production. We recommend including 0.60% TRM in finisher broiler diets, a safe, viable strategy to advance livestock value chains in resource-limited settings.
