| dc.description.abstract | The experiment was carried out to evaluate the effects of supplementation of
commercial layer feed on body weight, egg production and haematological
profile of the laying ducks rearing under the rural condition of Bangladesh.
Twenty indigenous ducks ( Khaki Campbell X Local duck) of 24 weeks
old was selected from a farm and randomly divided into four equal groups
(n=5) and numbered as group T0, T1, T2 & T3. The different amount of feed
was supplied into four groups for three months. The all four groups (T0, T1,
T2 and T3) were fed with routine feeding in scavenging condition. But T1
group supplemented with 120 gm, T2 group 60 gm and T3 group 30 gm
commercial feed. Significant differences were found in both egg production
and haematological profile of ducks in compared to control group. Egg
production was significantly (P<0.01) higher in T1 group compared to other
groups. During experimental period the body weight gain were shown the
same pattern being significantly (P<0.05) higher in T1 group compared to
T0, T2 and T3 groups. On the other hand, the values of total erythrocyte count
(TEC), total leukocyte count (TLC), haemoglobin content (Hb) and packed
cell volume (PCV) increased significantly (P<0.05) in the groups of T1 and
T2 compared to the control group (T0). But the value of MCV, MCH and
MCHC of T1, T2 & T3 groups decreased significantly (P<0.05) than that of
the control group. From the present study, it was revealed that the amount
of supplementation of commercial layer feeds was very important for
improving the haematological profile and egg production of ducks. So, the
additional commercial layer feed supplementation may be beneficial for
duck farming. | en_US |
