Effect of Locally Extracted Phytase on Blood Hematological and Serum Biochemistry of Broiler Chickens

Abstract

Experiments were conducted to examine the effect of locally extracted phytase on the performance of broilers with or without phytase supplementation on the blood hematological and serum biochemistry of broiler chickens.  A total of 180-day-old Cobb 500 broilers were randomly assigned to four treatment diets in a completely randomized design (CRD), with 15 chicks per replicate and three replications.  The experiment used a completely randomized design (CRD), and the birds were fed experimental feed containing phytase at 0, 300, 600, and 1200 FTU/kg for 42 days.  There were significant differences (P<0.05) among treatments for Packed cell volume (PCV), Hb, and WBC.  However, there were no significant (P>0.05) differences in RBC count, MCV, MCH, or MCHC of broilers fed the diet supplemented with enzymes.  Total protein, albumin, and globulin values did not increase significantly (P>0.05) in the supplemented groups compared with the T1 control group throughout the growth period.  The calcium concentration ranged from 1-1.49% and 0.75-0.89% in starter and finisher diets, respectively, whereas phosphorus ranged from 0.37-0.52% and 0.28-0.44% in starter and finisher diets, respectively, and it is within the range recommended in the broiler ration.  According to the results of this partial budget analysis, T4 (1200 FTU/kg) broiler chickensachieved higher profits than chickens classified as T2, T3, and T1, respectively.  Using phytase may be more profitable than feeding control.  There was no significant difference in mortality between treatments (P>0.05).
