| dc.description.abstract | The experiment was conducted on “Cobb 500” broiler chicks to investigate the effects of
lysine and methionine supplementation on body weight, hematological (TEC, Hb, PCV
and ESR) and biochemical (AST and ALT) parameters. A total of 200 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. Group T0 was kept as control and fed with only normal diet for 21 days
but the group T1, T2 and T3 were treated with lysine @ 1gm/L, methionine @ 1gm/L and lysine
@ 1gm/L & methionine @ 1gm/L drinking water with normal diet for 21 days respectively.
Body weight as gm of broiler chicks was measured on the day 14 of age (1
day of experiment)
and sequentially at 7 days interval up to the end of the experiment up to day 35 of age (21
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
st
day of experiment). It was observed that body weight were increased
significantly (p<0.01) in the treatment groups (T1, T2 and T3) as compared to control
group T0. TEC and Hb content also increased significantly (p<0.01) in all the treatment
groups as compared to control group. But the ESR, AST and ALT values were decreased
significantly (p<0.01) in the treatment groups. Therefore, it may be concluded that
additional lysine and methionine supplementation had better performance in terms of
body weight gain and hematobiochemical parameters without any detrimental effects in
broilers. | en_US |
