EFFECT OF DIETARY TURMERIC (CURCUMA LONGA L ) SUPPLEMENTATION ON SERUM BIOCHEMISTRY INDICES OF BROILER CHICKENS

Abstract

his study evaluated the effects of dietary turmeric (Curcuma longa L.) supplementation on the serum biochemistry of broiler chickens. Turmeric, containing curcumin, is renowned for its antioxidant, anti-inflammatory, and hepatoprotective properties, making it a promising feed additive in poultry nutrition. A total of 75 broiler chickens were randomly assigned to five treatments: T1 (control, 0 g turmeric), T2 (75 g turmeric per kg of feed), T3 (150 g), T4 (225 g), and T5 (300 g). Blood samples were collected at 28 days, and serum biochemical parameters, including glucose, total protein, albumin, globulin, urea, calcium, and magnesium, were analysed . Turmeric supplementation had no significant effects (p>0.05) on serum indices of broilers at starter phase. All the serum indices (Glucose, 91.67-95.38 mmol/L; Total protein, 4.94-5.37 g/dl; albumin, 2.65-4.20 g/dl; globulin. 1.29-2.29 g/dl; urea, 3.29-3.94 mg/dl; calcium, 8.02-9.17 mg/dl and magnesium, 1.54-1.99 mg/dl) fall within the normal range established by earlier studies. It was concluded that more studies to investigate turmeric levels beyond 300 g/kg should be conducted.
