Abstract

To investigate the impact of Enteococcus faecium as probiotic in layer chicks,
this bacteria was given in feed at a dose rate of 1.5 gm per kg feed, each kg of
feed contained 5×1011 cfu along the period of the study (57 days). 150 one day
old males were divided into five groups, 30 males each. The 1st group was given
the probiotic only in the feed, the 2nd group was given the probiotic and exposed
to high temperature and bad ventilation as a stress, and the third group was
given the probiotic with chlortetracycline in feed while the fourth group was
given the probiotic and then infected with E. coli on 21 day of age and the fifth
group was given feed with out probiotic as the control group. The results
showed that there was increase in body weight especially in the last weeks of the
experiment. Turbidity of the air sacs was mild in the four group compared with
control. Intestinal villi became elongated due to using of probiotic and there was
less sloughing compared with control, and those groups showed resistance
toward E. coli infection.
