Abstract:
The research was conducted to determine the effects of de oiled rice bran, protease enzyme
and halquinol in feed on the performance of broiler chicken. A total of 816 day-old IR
broiler chicks were allocated randomly to four treatment groups with six replications
having 34 birds per replication. All the birds were assigned to four treatments such as T
0
(Control), T
1
(Basal feed with 50 kg DORB and 500g Halquinol per metric ton of feed), T
2
(Basal feed with 50 kg DORB and 200g Enzyme Protease per metric ton of feed) and T
3
(Basal feed with 50 kg DORB, 200g Enzyme Protease and 500g Halquinol per metric ton
of feed). Result demonstrated that the highest body weight (g) was found in T
3
(1817.75 g)
and lowest result was found in T
2
(1780.58 g) group. But, higher body weight was found
in T
3
group than control group T
0
and that was statistically significant (P<0.05). The
highest body weight gain was found in T
3
IX
(1776.75 g) and lowest result was found in T
0
group (1744 g) and that was statistically no significant (P>0.05) difference. The highest
result was found in T
2
(2379.39 g) and lowest result was found in T
3
group (2318.46 g) and
that was statistically significant (P<0.05). The best FCR was found in T
3
(1.47) and worse
FCR was found in T
1
and T
2
group (1.56) but better FCR was found in T
3
(1.47)
than control
group T
0
(1.54) and that was not statistically significant (P>0.05). Survivability rate (%)
was higher in treated group T
3
than control group T
0
. There was significant difference
(P<0.05) in survivability rate (%). BCR was non significantly higher (P>0.05) in treatment
group T
3
(1.49) than control group T
0
(1.41). The above research was found that body
weight (g), body weight gain (g), survivability rate (%) and BCR were better result in T
3
group than other groups including control group T
0
(Basal feed). FCR was better in T
3
group than other groups including control group T
0
(Basal feed). Better result was found
in T
3
(Basal feed with 50 kg DORB, 200g Enzyme Protease and 500g Halquinol per metric
ton of feed)
group than control group.
