| dc.description.abstract | The experiment was conducted on “Cobb 500” broiler chicks to investigate the effects of
probiotics, enzymes and liver tonic supplementation on live weight and hematobiochemical
parameters (TEC, Hb concentration, PCV, ESR, TLC, AST and ALT). A total of 250 day-old
broiler chicks were allowed to take rest for 13 days for the adaptation and supplied with normal
diet and water. After day 13 they were randomly divided into four equal groups (N=50) and
marked them as group T0, T1, T2 and T3. Broiler chicks of group T0 were kept as control and fed
with only the commercial broiler ration and fresh drinking water for 21 days but the group T1, T2
and T3 were treated with probiotics (Protexin
) @ 1gm/L,
probiotics (Protexin
®
) @ 1gm/L, enzymes (Alquerzim
®
) @ 1 gm/L plus liver tonic
(Livavit
®
) @ 1gm/L plus enzymes (Alquerzim
®
®
) @ 1ml/L drinking water with normal diet for 21 days respectively. Live weight as gm
of broiler chicks were measured on the day 14 of age (1
day of experiment) and sequentially at
7 days interval up to the end of the experiment (day 35 of age i.e21
st
day of experiment). For the
hematobiochemical examinations, blood samples were collected from the randomly selected 10
(i.e. n = 10) birds from each and every group at the end of experiment on day 35 of age (21
st
day
of experiment). It was observed that live weight were increased significantly (p<0.01) in
the treatment groups(T1, T2 and T3) as compared to control group T0. TEC, Hb
concentration and PCV were increased significantly (p<0.01) but the ESR and TLC
significantly (p<0.01) decreased in all the treatment groups as compared to control group
st
T0. Serum biochemical parameters like AST and ALT values were also decreased
significantly (p<0.05) in the treatment groupsas compared to control group T0. Therefore,
it may be concluded that additional probiotics, enzymes and liver tonic supplementation had
better performance in terms of live weight gain and hematobiochemical parameters
without any detrimental effects in broilers. | en_US |
