Use of Cinnamon and Black Cumin as Effective Alternative of Antibiotics on Growth Performance of Broiler

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.
