Abstract EN
Effects of commercial probiotic (Bactocell) on growth performance and blood parameters were evaluated.
A total of 800 one day-old Ross broiler chicks were raised over 42 days.
Chicks were wing-banded, weighed individually and randomly allocated into four equally major groups each having two replicates.
Chicks of group 1 (control group) were fed the starter and finisher diets that did not supplemented with probiotic.
The chicks of groups 2, 3, and 4 were fed the control starter and finisher diets supplemented with 1.6 g, 1 g and 0.8 g of probiotic per kg feed, respectively.
Weekly body weight, feed consumption and feed conversion were measured.
Blood parameters at 1, 4 and 6 weeks of age including packed cell volume (PCV), haemoglobin (Hb), total protein, albumin, total lipid and cholesterol were determined.
All birds were kept under similar environmental, managerial and hygienic conditions.
The results of the current study revealed that there was no significant change for Hb and PCV concentrations among different groups at all studied times.
Also, total protein, lipids and albumin concentrations were not affected by probiotic supplementation.
Chicken fed a diet containing various levels of probiotic showed a significant decrease (p 6 0.05) in cholesterol concentration compared to control group.
Probiotic supplementation significantly increased the body weight and daily weight gain of broiler chicks at late ages (3–6 weeks).
Also, the birds fed on probiotic levels 1 and 0.8 g / kg diet exhibited higher body weight among chicken groups at 6 weeks of age.
Improved feed conversion was noticed in birds fed a diet supplemented with probiotic.
There was no significant difference in mortality rate among groups.
We concluded that use of selected commercial probiotic resulted in improved performance parameters
