Taking into account that a recent study did not show any association between sow parity and infection probability of piglets (TOBIAS et al., 2014a), hyperimmunization
of any parity number-sows would be a good strategy to ensure a high level of colostral antibodies in piglets.
OTf anti-sera were prepared by rabbits' hyperimmunization
with OTf SPF.
of rabbits was performed according to the method of B.
We now know that hyperimmunization
of cows is not a requirement for colostrum's broad spectrum capabilities and that fresh, raw colostrum can be made into supplements with an extended shelf-life.
Development detection and application of eggyolk antibodies produced against avian viral arthritis (AVA) by hyperimmunization
. Chinese J.
Pigs vaccinated with the trivalent vaccine with carbomer adjuvant showed almost no antibodies against pandemic (H1N1) 2009 virus, although the vaccine strain reacted well in hyperimmunization
This protocol was found to be effective for hyperimmunization
. Eggs were gathered daily and antibodies were purified from yolk with a polyethylene-glycol and chloroform modified method.
Schemes for hyperimmunization
could help other livestock as well.
For the experiments, biomass and antigen were obtained for hyperimmunization
and production of diagnosticum strains of many serogroups: Icterohaernorrhagiae, Javanica, Grippotyphosa, Canicola, Pomona, Tarassovi, Hebdomadis, Bataviae, Autumnalis, Ballum, Pyrogenes, Australis, Cynopteri.
of steers with J5 Escherichia coli bacterin: effects on isotype-specific serum antibody responses and cross reactivity with heterogeneous gramnegative bacteria.
with European SIVs of subtype H1N1, H3N2, or H1N2 resulted in high titers to the homologous viruses.
