Abstract:

Haemato-biochemical values of Ross 308 broiler chickens fed diets with different supplementation levels of Moringa oleifera leaf meal (MOLM) were determined. A total of 500, day-old Ross 308 broiler chicks were used for the study. They were divided into 5 groups (T1, T2, T3, T4 and T5) of 100 chicks each, and each group was replicated five times. Birds in group T1 (control) received basal diet (BD) supplemented with MOLM at 0 g/kg feed, while birds in groups T2, T3, T4 and T5 received the BD supplemented with MOLM at 25, 50, 75 and 100 g/kg feed, respectively, in a completely randomised design. MOLM supplementation level with the best haemato-biochemical values was modelled using quadratic optimization function. MOLM was rich in protein (32.37%) and moderate in minerals. Birds on 50 and 75 g MOLM/kg feed had higher (p<0.05) packed cell volume (PCV), red blood cell (RBC) and glucose than those on the other 3 treatment diets. The white blood cell (WBC) counts for birds on 50 g MOLM/kg feed were higher (p<0.05) than those on 100 g MOLM/kg feed but similar (p>0.05) to those on 0, 25 and 75 g MOLM/kg feed. Blood platelet count maintained the trend 75 > 0  > 50 > 100 > 25 g MOLM/kg feed with birds on 75 g MOLM/kg feed been statistically higher (p<0.05) than those on 25, 50 and 100 g MOLM/kg feed. Dietary MOLM supplementation had no significant effect (p>0.05) on haemoglobin (Hb), total serum protein (TSP), albumin, cholesterol and uric acid. Triglyceride (TG) level of birds on 25, 75 and 100 g MOLM/kg feed decreased significantly compared to those on 0 and 50 g MOLM/kg feed. Daily MOLM supplementation had a significant effect (p<0.05) on the differential WBC count. Daily MOLM supplementation with 26.99 and 31.95 g/kg feed, respectively, supported optimum PCV (38.62%) and glucose (245.42 mg/dl) in Ross 308 broilers. It is therefore summarized that optimizing MOLM supplementation level in the ration of Ross 308 broilers could assist in improving their productivity.
