Influences of Prebiotic on Growth Performance and Hemato-Biochemical Parameters in Broiler During Heat Stress

Abstract

The study was carried out to investigate the effect of prebiotic on growth performance, hematological (TEC, Hb, PCV, ESR) and biochemical (Cholesterol, Uric acid) parameters in broilers during high environmental temperature. A total of 30, at 7 days old (Cobb-500) broilers were randomly divided into 3 groups (n=10). Broilers held at 35 ± 2°C temperature and 70±5% relative humidity were considered as heat stressed those kept at 25 ± 2°C and relative humidity 60 ± 5% were considered as normal. Normal control group (NE-T) was provided with the normal diet. Heat stressed groups consisted of HS-A as provided with normal diet; HS-B provided with the normal diet with 0.2g prebiotic (A-MOS). The results revealed that supplementation of prebiotic significantly (p<0.01) increased the live body weight as compared to heat stressed but without prebiotic supplement. The highest weight gain was recorded in normal control group (1623.00e±7.176 gm) and the lowest weight gain was recorded in HS-A as heat stress group (1303.00e ± 4.899 gm). The hematological parameters (TEC, Hb, PCV, ESR) were also significantly (p<0.01) varied in comparison to the both control. The uric acid a biochemical parameter varied significantly (p<0.05) among groups. Therefore, it is may be concluded that prebiotic is helpful for the maintenance of broilers performance under heat stress condition.
