Abstract

The effect of vitamins, minerals and probiotics supplementation to the balanced ration of the broiler chicks on the immune response and growth performance after vaccination with BCRDV was evaluated. For this 50 broiler birds were divided into five equal groups such as A, B, C, D and E, and five types of separate treatments with normal poultry feed were provided to the indivisual experimental groups. All the birds were vaccinated with BCRDV primarily at 3 days of age and boostered at 17 days of age. The birds of group A, B, C and D were supplemented with only probiotics, mixture of probiotics and minerals, mixture of probiotics, minerals and vitamins, respectively. The birds of group E were kept as vaccinated control. Blood samples were collected at the age of 9, 12, 16, 23, 26 and 30 days sequencially. The serum antibody titres were measured by HI test and ELISA. The highest value of HI antibody titre was 384±242.65 (Mean ±SD) in group B at 23 days of age. The lowest value of HI at 23 days was 56±32.86 (Mean ±SD) obtained in group C. The ELISA antibody titre was also highest (4675.12±485.72) at 23 days in group B and obviously the lowest (2169.38±724.45) in control group E. In case of group C, the ELISA antibody titre was 3105.73±877.57 at 23 days but then the titre decreased gradually compared to control group. The highest body weight (1420±90.82) was recorded at 30 days of age in group D and the lowest value (1188±44.38) was in group B.
