Abstract
Broiler chicks of a commercial strain were fed diets containing
Bacitracin Methylene Disalicylate @150 g and 200 g/MT and
Virginiamycin 500g/MT feed upto 6 weeks of age to evaluate their
effects on growth, feed efficiency, carcass characteristics and
bacterial population (Salmonella and E.
coli ). Both BMD
and virginiamycin significantly increased (P<0.01) the body weight
gains as compare to the control and also improve the feed
conversion ratio. The carcass characteristics showed the highest
edible weight was recorded in treatment IV where virginiamycin @
500g/MT feed was incorporated (76.86%), followed by treatment III
(71.92%), treatment II (71.41%) and the lowest (70.68) in control
(T-I). The sample of excreta collected during II, IV and VI week
of experiment did not show any incidences of S almonella in
any treatment groups, however, the excreta of six week in all the
treatment groups showed the incidences of E.
coli.
