Abstract:
ABSTRACT
The experiment was conducted with Cobb-500 broiler strain. For this purpose 360 broiler chicks were
purchased from Kazi Hatchery, Gazipur, Dhaka. The experiment was conducted in the month of
November and December 2013 for 28 days at SAU Poultry farm. There were six treatments, Such as,
T1: 0.25 % of cinnamon/ black cumin; T2: 0.50 % of cinnamon/ black cumin; T3: 0.75 % of
cinnamon/ black cumin; T4: 1.0 % of cinnamon/ black cumin; T5: Basal Diets + Antibiotics and T6:
Control (Basal Diet with no antibiotics or cinnamon/ black cumin) The number of replications was
three for each treatment. So the total number of replications was 18 units which were randomly
selected. Each replication had 10 chicks. Two experiment was conducted both for Cinnamon and
Black Cumin at same time. The best common cinnamon and black cumin dose was 0.50% for feed
consumption. For both cinnamon and black cumin, the height LW was found in 0.75 % level. The
FCR results indicated that any dose of cinnamon and black cumin can be used for best FCR. The
analytical results of mortality both for cinnamon and black cumin showed no significant difference
(P>0.05) within them. So considering market price 0.25% or 0.50% dose of cinnamon or black cumin
can be used for best survivevality. Similarly, lower doses of cinnamon and black cumin were suitable
to keep lower blood glucose and blood cholesterol level. SP ratio for Gumboro disease were
significantly higher (P<0.05) in all cinnamon supplementation groups which had positive effects on
immune responses, whereas higher doses of black cumin showed positive effects on immune
responses. SP ratio for Newcastle disease were significantly higher (P<0.05) in all cinnamon
supplementation groups which had positive effects on immune responses. But, cumin
supplementation groups had not positive effects on immune responses.
