The Effect of Awara Waste (Soybean By-product) on Haematology and Serum Biochemical Parameters of Broiler Chickens

Abstract

This experiment was conducted to determine the effect of Awara waste (soybean by-product) on hematology and serum biochemical parameters of broiler chickens. Five diets were prepared as follows: Control: soybean meal-based basal diet, AW15: basal diet added with 15% Awara waste, AW30: basal diet added with 30% Awara waste, AW45: basal diet added with 45% Awara waste and AW60: basal diet added with 60% Awara waste. Two hundred 4-week-old Ross 308 broilers were randomly divided into five groups of 40 birds and each group was also divided into four replicates in a completely randomized design. The experiment lasted for 42 days, during which ad libitum feed and water were provided. Hematology results showed that only red blood cells and hemoglobin levels were significantly affected (p<0.05) by the diets. The AW30 diet showed similar RBC levels to the control on days 14 and 42, with higher levels compared to other diets. AW30 had highest Hb level on day 14, similar to the control diet on day 42. Total protein, albumin, globulin and cholesterol levels varied significantly (p<0.05) among diets. Control and AW30 diets had higher total protein on days 14 and 42, albumin levels were higher in the control diet on both days but lower in AW15-60, and globulin levels were higher in AW15 diet. Cholesterol levels were higher in control and AW45-60 on day 14, and lower in AW15-30. Based on these findings, AW15-30 is recommended for broiler chickens.
