| dc.description.abstract | The experiment was conducted on Cobb-500 broiler chicks to evaluate the effects
of probiotics and enzymes supplementation on growth performance and
hematological parameters (TEC, Hb concentration, PCV and ESR). A total of 160,
14 days old broiler chicks were reared throughout the entire period of study. The
chicks were divided randomly into four groups with 40 broiler chicks in each
group. Group A was designated as control group was given only normal broiler
ration and rest of the groups were supplemented by probiotics and enzymes
[Group B ( probiotics preparation Protexin® @ 1gm/L)], [Group C (enzyme
preparation (Alquerzim® @ 1gm/L)] and [Group D (probiotic Protexin® @
1gm/L and enzyme Alquerzim® @ 1 gm/L)] with drinking water from 1
st
to
21
th
day of experiment. It was observed that probiotics and enzymes
supplementation enhanced the body weight of broiler chickens. At the final day
of experiment the body weight was significantly increased (P<0.01) in the
treatment groups in comparison with that of control group. TEC, Hb
concentration, PCV values were significantly increased (P<0.01) in treatment
groups than the control group but ESR level was decreased significantly (P<0.01)
than the control group. So the farmers of Bangladesh can be benefitted by using
probiotics and enzymes in broiler chicken ration. | en_US |
