The Changing of Broilers’Blood Component at Various Environmental Temperatures and Times of Sampling

This study was conducted to evaluate the effects of environmental temperatures and ages (time of sampling) on erythrocyte number (Er), hemoglobin concentration (Hb) and hematocrite value (Hm). Ninety 14-d old broilers were used in 3 x 4 completely randomized design in split plot 3 x 4 reared in three environmental chambers (25.55±1.45; 29.29±1.27 and 31.59±1.05°C as T1, T2 and T3 respectively), and four times of sampling (0, 4, 8 and 16 days after factor of treatment environmental temperature as S0, S4, S8 and S18 respectively). The results showed in general that T2 and T3 significantly increased in Er and Hm. The numbers of erythrocyte and presentation of hematocrite of T3S4 were higher and T1S8 were lower than all. The level of hemoglobin of S0, were higher than the others. It was concluded that a high environmental temperature and time sampling could affects the blood component of broilers.
