Abstract

Recent reports shown that the supplementation of the broiler ration with a
probiotic leads to an ideal microbial balance in the intestinal microflora of their
gastrointestinal tract. Such balance, however, would reflect on their health and
performance. The aim of the present study was to compare the effect of two
probiotic products, Biomin and Iraqi probiotic, on the broiler performance
characteristics. A total of 500 Lohman broiler chicks, one day old, were
randomly distributed into five dietary groups as follow:
T1: chicks fed on diet with half dose of Biomin (1.5 Kg/ Ton diet).
T2: chicks fed on diet with full dose of Biomin. (3 Kg/ Ton diet)
T3: chicks fed on diet with half dose of Iraqi probiotic. (2.5 Kg/ Ton diet)
T4: chicks fed on diet with full dose of Iraqi probiotic. (5 Kg/ Ton diet)
T5: chicks fed slandered diet. (Control)
Results obtained from the present study showed that the supplementation of the
diets with probiotic, biomin or Iraqi probiotic, had significantly (ρ > 0.05)
improved the final body weight, feed conversion and dressing percentage and
decreased mortality. However, Iraqi probiotic seemed to be more effective than
biomin in most of these treats. Furthermore, the use of a half dose of Iraqi
probiotic (2.5 Kg / ton feed) seemed to be better than the full dose.
