A study was undertaken to determine the immune response of eight different imported live NDV vaccines in broiler chickens in the Department of Microbiology and Hygiene, Bangladesh Agricultural University, Mymensingh during the period from July to December 2008. A total of 55 broiler chickens (Ross breed) were divided into eleven groups such as 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11 of which group 1, 3, 5, 7 and 9 were vaccinated primarily with Nobilis® MA5+Clone30, Avipro® ND-IB HB1, Cevac® BIL, Newcastle-Bronchitis Vaccine Fortdodge® and Avipro® ND LaSota vaccine respectively at day 5 of age and secondarily with Nobilis® ND Clone 30, Avipro® ND LaSota, Cevac® New L, Newcastle Disease vaccine Fortdodge® and Avipro® ND LaSota vaccine respectively at day 21 of age by single eye instillation and 2, 4, 6, 8 and 10 were vaccinated with the same vaccines respectively by double eye instillation following the same schedule. Group 11 was kept as unvaccinated control. Sera samples were collected after 10 days of each vaccination and at day 5, 15, 20, 31 of age from nonvaccinated control and subjected to HI test for the determination of antibody titres. It was observed that after primary vaccination the geometric mean (GM) of HI titres of double eye vaccinated groups differed significantly (P

An experiment was conducted to investigate the effects of replacing antibiotic growth promoter (AGP) with a combination of essential oil and organic acids (EO + OA) on growth performance, gut microbiota and immune response in broiler chickens. In Experiment 1, 320 day-old broiler chicks were randomly distributed to 32 pens with 10 birds in each pen and the pens were equally allotted to four treatment groups. In Experiment 2, 120 day-old chicks were divided into the same four treatment groups, each group containing three replicated pens with 10 birds in each pen. The groups were (1) Negative Control (NC) without AGP or other growth-promoting feed additives; (2) AGP (NC + enramycin; 125 mg/kg feed; (3) OA (NC + OA; 500 mg/kg feed); and (4) EO + OA (NC + a combination of cinnamaldehyde and calcium formate; 500 mg/kg feed). Experiment 1 lasted for 40 days, whereas Experiment 2 continued for 28 days. In Experiment 2, all birds were orally challenged with Escherichia coli (108 bacteria/bird) on Day 14. Overall intake, growth and feed conversion ratio (FCR) on Day 40 had no difference (P > 0.05) among the groups in Experiment 1. In Experiment 2, growth, feed intake and FCR were not affected by any dietary treatments until Day 14, but after being challenged with E. coli, bodyweight gain and FCR improved (P < 0.05) for AGP and EO + OA compared with NC. Mortality rate was also lower (P < 0.05) for AGP and EO + OA than NC in Experiment 2. Villi height was higher (P < 0.001) in OA and EO + OA groups compared with NC and AGP groups. Any treatment did not affect (P > 0.05) the counts of total bacteria, E. coli and Lactobacillus in the contents of ileum and caecum. However, Salmonella counts in the ileal and caecal contents decreased (P < 0.001) for AGP, OA and EO + OA compared with NC group. Clostridium counts were lower for EO + OA group than for NC and AGP groups in the ileum, and for AGP, OA and EO + OA groups than for NC in the caeca (P < 0.05). Antibody titer on Day 35 against Newcastle disease vaccine was higher in EO + OA group than in NC, AGP and OA groups (P < 0.001). In conclusion, EO + OA did not affect growth and FCR in broilers. However, AGP and EO + AO improved growth performance and FCR after being challenged with E. coli. Moreover, EO + OA was effective in reducing the Clostridium count in the small intestine and caecum and increasing the villus height and antibody titer against Newcastle disease vaccine.

This trail was suggested to evaluate the amount of inherited haemagglutination inhibition (HI) antibodies for Newcastle Disease (ND) from hens to their own progeny via yolk, blood samples were collected from broiler breeders at 51st week of age aiming the collection their sera, these hens were previously vaccinated with ND-killed vaccine at the age 5 and 120 days respectively via subcutaneous route; and ND-alive vaccine at 1and 18 days then monthly intervals by aerosol, random samples of eggs were collected from panels or hatchery machines either after 24h., to detect amount and location of HI antibodies through them, day old chicks were submitted to the same protocol of blood collection as well as mothers. The results showed that the combination manner of vaccines is an ideal way of HI antibodies peak elevation, these antibodies can pass vertically from dam to progeny through yolk, and the yolk material can be used to detect the HI antibody titer by routine process.

The present study performed to evaluate the impact of addition ofThymbra spicata leaves powder of aflatoxin contaminated ration inreduction of the aflatoxin immuno suppressive effect in the immuneresponse induced by Newcastle disease vaccine in broilers.The study conducted in three groups, The first group fed aflatoxin freeration, second group fed aflatoxin contaminated ration without anytreatment, while the third group fed aflatoxin contaminated rationsupplemented of 2% Thymbra spicata leaves powder.All chick groups were vaccinated twice with Newcastle disease vaccine(NDV) at 10 and 20 days of age. ELIZA test was carried out to estimate thehumeral immune response at 6, 19 and 31 days of age. Infection challengwere done at day 32 of age with velogenic ND strain (Z-2003).The results showed that the first group has high significante antibodies titerreach to 3239±249.3 at 19days of age and 10186+845.3 at 31 days of agewith significant level 0.01 and high protection ratio against challenge(100%)at 32 days of age, while the second group has the low antibodies titerreach to 2622.6±27.3 at 19 days of age and 5712.5±786.9at 31daysof ageand low protection ratio against challenge(66.67), the third group’santibodies titer and protection ratio lower than first group and higher thansecond group ,the titers are 3060±542.5 at 19 days of age and 5712.5±786.9at31 days of age while the protection ratio against challenge is 80% at 32days of age .The results showed the immuno suppressive effect of aflatoxin as in secondgroup and the role of Thymbra spicata leaves powder in reduction of theseeffect.

The study was conducted to determine the persistence of maternally derived antibody (MDA) and its effects on protection against NDV in broiler chickens and to investigate the status of humoral immune response following vaccination with BCRDV® (F-strain, lentogenic) at different ages of broiler chickens during the period from August to October,  2008. A total of 90 day-old broiler chicks of Cobb 500 strain with the history of vaccination of parent stock against Newcastle disease (ND) was divided into three groups (A, B and C). Birds of group A (n = 35) were used for the study of protection ability of MDA against NDV, the birds of group B (n = 45) were used for the measurement of humoral immune response in chickens following vaccination at different ages and birds of group C (n = 10) were used for the determination of persistence of maternally derived antibody. The level of antibody titre against NDV was determined by HI test. The protective potentiality of MDA and vaccine was determined by the rate of survivability of the chickens following challenge infection. It was observed that the MDA titre in day-old chicks was higher and gradually declined at minimal level at day 28. The MDA titre of 128 or above protected the birds following challenge infection with virulent NDV. There were significant decrease in HI titres of chickens which were vaccinated once at day 1 and day 7, and could not withstand challenge infection with virulent NDV. Single vaccination with BCRDV® at day 14 triggered the production of antibody but could not provide complete protection to the birds. The birds which were boosted with the same vaccine 7 days and 21 days after primary vaccination produced better immune response. However, the birds which were vaccinated primarily at day 1 and boosted at day 7 could not withstand the challenge completely. Of the other regimens of twice vaccination, primary vaccination at day 7 and booster dosing at day 28 was found to be the best in terms of immune response and protection potentiality. Therefore, it may be concluded that (a) The MDA titre level of 128 or above is sufficient to protect broilers against challenge with virulent NDV,( b) Primary vaccination at day 7 followed by a booster dosing at day 28 may be followed for better immune response and protection against ND in broilers.DOI: 10.3329/bjvm.v7i2.5995Bangl.
