“…The currently used Hitchner B1 and La Sota strains of live virus vaccines are very efficient Passive immunity to NDV is important in young chicks during the first few weeks after hatching. Passive immunity can be effectively established and preserved at an appropriate level by periodic monitoring of maternal antibody titers, because the dam's antibodies are transferred to day-old chicks through egg yolks (Heller et al, 1977). For the primary vaccination of young chickens against viral poultry diseases such as ND and IBD, live vaccines are mostly used.…”

Newcastle Disease virus (NDV) and Avian Influenza virus (AI) are represent a great negative significant causing severe economic losses and increased mortalities worldwide. Newcastle disease (ND) and Avian Influenza (AI) vaccination were targeting to lower the losses from mortality, reduce the viral load in the environment as well as eradication of positive cases. Many immunostimulants had been used to improve the immune response of vaccinated chickens. The current study was designed to compare the effect of different immunostimulants on chick's immune response to bivalent ND with AI-H5N1 oil vaccine. One hundred and ten, 1-day old Baladi chicks, At the 1 st day of life (0 day) 10 birds were sacrificed to obtained individual blood samples for serum to determine maternal antibodies (MDAbs) to both AI and ND. Rest of birds (100 chicks) were divided into 5 equal groups (1-5); each 20 chicks. All chicken groups were vaccinated against ND with eye drop instillation of HB1 vaccine. While, at the 9 th day birds of the groups 1-3 and 5 were given H5N1 vaccine by S.C injection, birds of group 4 were lifted as non AI vaccinated control. The used immune stimulants under test were given to groups 1, 2, and 3 as follows Lector, Superimmune and Imuvral; respectively. All the groups were subjected to daily observation with recording of feed intake, weekly body weight gain and total FCR, Weekly serum samples were collected, for serological examination, and the results showed high antibody titers, low mortality rates and better body performance in the groups treated with immunostimulants than the other groups which were not treated with the immunostimulants

“…The use of vaccination to control Salmonella infection in chickens is inevitable. Live vaccines produce better protection than do killed vaccines (1,2,8,19,28,31,33,40,45), but killed vaccines appeal more to producers and regulators because they do not pose the possible public health risks that accompany the use of a live attenuated paratyphoid vaccine in the poultry industry. However, killed vaccines do not induce enough protection to eliminate the Salmonella carrier status in chickens (2).…”

“…Passive immunity is engendered in chicks by the transfer of predominantly immunoglobulin G (IgG) antibody to the eggs (7,13,31,32,38). Maternal antibody is sequestered by the developing oocyte (14) and transported from the egg yolk across the yolk sac membrane into the embryonic circulation (7,33).…”

The avirulent Salmonella typhimurium 3985 was used to vaccinate white leghorn chickens at 16 and 18 weeks of age, and the effect of maternal antibody on Salmonella colonization of progeny of vaccinated hens was assessed with S. typhimurium F98 or 3985. Progeny of hens that had been vaccinated at 1 and 3 or 2 and 4 weeks of age with 3985 were used to determine the effect of maternal immunity on vaccine efficacy. Vaccination of hens induced long-lasting Salmonella-specific antibodies which were transferred into eggs and were detected as immunoglobulin G (IgG) in the egg yolk. Maternal antibody was detected in the progeny of vaccinated birds as IgG and IgA in serum and intestinal fluid, respectively. The titer of maternally transmitted IgG or IgA was highest in the first week of life of the progeny and declined with age. Maternal antibodies prevented colonization of the chicks by S. typhimurium 3985 and reduced colonization by S. typhimurium F98. Overall, chicks from vaccinated hens had significantly higher antibody responses than did the progeny of nonvaccinated hens after oral infection with Salmonella strains. Maternal antibody reduced the efficacy of vaccination of progeny with 3985 at 1 and 3 weeks of age. But vaccination at 2 and 4 weeks of age induced excellent protection against challenge with S. typhimurium F98 or S. enteritidis 27A PT 8 in birds from vaccinated hens and in specificpathogen-free chickens. Vaccination of chickens at 2 and 4 weeks of age has been shown to protect the birds against challenge with homologous and heterologous Salmonella serotypes. A combination of vaccination of adult animals and use of the progeny of vaccinated birds will enhance effective control of Salmonella infections in the poultry industry. This will complement the present control of Salmonella-associated food poisoning caused by Salmonella enteritidis in eggs because the avirulent S. typhimurium vaccine strain 3985 induced excellent protection against S. enteritidis in chickens.

“…Immunoglobulins in birds are deposited into the egg yolk and chicks absorb these antibodies into their developing systems. The yolk contains mainly IgG which becomes the circulating antibody in the chick, while the albumen contains predominantly IgA which is swallowed by the developing chick, thus coating its mucous membranes with the IgA (Brierly, 1956;Heller et al, 1977). The levels of passively acquired maternal antibodies in the serum of a day-old chick are approximately the same as those found in the serum of the hen (Allan et al, 1978).…”

“…In the clucken, CY given in newly hatched birds leads to severe and permanent deficiency in the humoral immune response. Eskola et al (1974) found that CY given in ovo caused severe humoral immunodeficiency when administered on days 14-16 or on days 16-18 of incubation. The suppressive effect, however, was found to be reversible and the fiinctional and morphologic recovery of antibody producing tissue occurred after 10 weeks following treatment (7,14).…”
