Abstract:
A feeding trial was conducted on 200 day-old Lohman meat broiler chicks for a period
of 35 days in the poultry farm of Sher-e-Bangla Agricultural University, Dhaka. The
aim of the study was to assess the efficiency of dietary organic Se, inorganic Se and
their combined dose on the production index, blood parameters and immunity of
commercial broiler chicken. The chicks were assigned to 4 treatment groups comprising
of T
1
(control), T
2
(1.5ml/l organic Se), T
3
XIII
(0.75ml/l inorganic Se) and T
4
(combined
Se) randomly. Treatments were replicated five times with 10 chicks per replication. The
results showed that dietary supplementation of organic Se, inorganic Se and their
Combined dose had significant (P<0.05) difference on feed consumption, body weight
gain, final live weight, dressing percentage of broiler compared to control group. Higher
feed consumption found in T
4
(1126.40±18.99g) group compared to other groups.
However, superior final live weight (2257.66±27.95g) obtained in T
4
group where birds
fed with combined dose of Se compared to those other treatment and control group.
Improved FCR value (1.46±.00) found in T
3
group which is statistically significant
(P<0.05) with the values of other groups. Dressing percentage is also higher in T
3
(75.10±0.90) group where birds fed with 0.75ml/l inorganic Se. Dietary
supplementation of organic Se, inorganic Se and their combined dose had no significant
(P>0.05) effect on the abdominal fat weight in different treatment groups. Birds
supplemented with combined dose of Se (T
4
) showed insignificantly (P>0.05) higher
abdominal fat weight (31.90±1.603g).The glucose concentration had no significant
(P>0.05) difference among all treatment groups but cholesterol concentration had
significant (P>0.05) difference among all treatment groups and comparatively lower
cholesterol level 143.60±15.79mg/dl was found in 0.75ml/l inorganic Se (T
3
)
supplemented group. In addition, the hematological parameters including white blood
cell (WBC), lymphocyte and granulocyte which were significantly (P<0.05) lower in
organic se, inorganic se and their combined dose groups compared to control group.
Diets supplemented with organic se, inorganic se and their combined dose had no
significant (P>0.05) effect on blood parameters compared to control group. Birds fed
with 0.75ml/l inorganic se (T
3
) supplemented diet achieved superior result.
