Four hundred, one day old chicks, of four hybrids, were divided into four groups, reared on the floor for ten weeks. The hybrids were vaccinated with live IBD vaccine at 14, 35, 56 days. Maternal antibody titers, antibody titer after each vaccination and bursa index were measured. Results revealed that the Barred local hybrid showed a highest maternal antibody titer and antibody titer after each vaccination, more bursa index lowest mortality. Highly significant correlation (P<0.01) & more linear regression between antibody titer & maternal antibody titers were observed in the barred hybrids.

The purpose of the present study was to investigate the effects of Gingyo-san (GGS), a traditional Chinese medical formula, on peripheral lymphocyte proliferation and serum antibody titers in chickens vaccinated against the infectious bursal disease (IBD) virus. Treatment groups were fed one of three doses of GGS in their diet (0.5%, 1.0% and 2.0%, w/w), and the IBD vaccine was administered at 1 and 3 weeks of age. At Weeks 8, 12 and 16, changes in serum IBD antibody titers were measured via the micro-method and T cell proliferation. In gene expression experiments, GGS-treated peripheral T lymphocytes were stimulated with concanavalin A (ConA) for 24 h. The mRNA expression of interleukin-2 (IL-2), interferon-γ (IFN-γ), interleukin-4 (IL-4) and interleukin-12 (IL-12) was determined using a semi-quantitative RT-PCR assay. The results showed that a low dose of GGS could significantly raise the antibody titers. Medium and high doses of GGS enhanced IL-2 and IFN-γ production. GGS altered the expression of IL-4 and IL-12 in T lymphocytes. CD4+T lymphocyte development was also skewed towards the Th1 phenotype. GGS enhanced cell-mediated immunity and augmented the effects of IBD vaccination in strengthening subsequent anti-viral responses.

Infectious bursal disease (IBD) is one of the most endemic diseases of commercial poultry in Ethiopia. Vaccination has been practiced as the major means of IBD prevention and control. A study was conducted to determine and compare the immunogenicity of two commercially available IBD vaccines in broiler chicken with maternally derived antibody (MDA). Day-old chickens of 270 were randomly assigned to three groups, group 1 vaccinated with brand 1 vaccine at 7th and 19th days and group 2 with brand 2 vaccine at 15th and 22nd days while group 3 were kept as control. Six chickens were also randomly selected and bled on day 1 for differential leukocyte count (DLC) and determination of MDA. Representative chickens from each group were bled at 24th and 42nd days of age for antibody titration using the indirect ELISA test. DLC scores were determined in the 1st and 24th days. The result revealed highly significant differences (P = 0.001) between group 1 and group 2 in DLC at 24th days of age. Antibody titers against IBD were differed significantly (P = 0.02) at 24th and 42nd days of age in broilers vaccinated with brand 1 and brand 2 vaccines. It is concluded that although both brands of vaccine induce an adequate immunological response at the end of the experiment, brand 1 vaccine has shown significantly high antibody titers against the IBDV and DLC than brand 2.

The Mean

A study on Infectious Bursal Disease (IBD) was conducted on broiler chicks (N=200+70) of strains: Cobb-500 and Hubbard classic at Laxmipur district of Bangladesh. The blood sample were collected at day old chicks (1st day), pre-vaccinated flocks (11th day) and post-vaccinated flocks (26th day), to measure the antibody titer by indirect ELISA method. Maternal derived antibody (MDA) mean titer of day old chicks (N=40) were found 9621.65 ± 780.78 and 4232.60 ± 301.66 for Cobb-500 and Hubbard classic respectively. MDA mean titer was measured at day eleven chicken (N=60) before vaccination and found 1963.00 ± 143 and 984.16 ± 126.4037 respectively. Of these two titers; Cobb-500 strain was found to be protective (>1000) where Hubbard classic was below protective (<1000) titer level. The two flocks of Cobb-500 and Hubbard classic strains of broiler chickens were vaccinated with intermediate (Bursine-2) and intermediate plus (IBD Blen) vaccine respectively at day twelve and serum was harvested on day twenty six. The mean serum titers were found 131.30 ± 36.04 and 7413.54 ± 569.39 in Cobb-500 and Hubbard classic respectively, where mean titer level of Cobb-500 was below the minimum protective level but Hubbard classic strain was developed 7413.54, protective level. These results were indicating that the maternal derived antibody titer persists above 1000 level hindering the development of antibody titer in vaccinated flocks. However, persistence of MDA titer above 1000 may causes of vaccination failure of IBD vaccine.International Journal of Natural Sciences (2014), 4(2) 22-27
