Abstract :

The effect of coccidiosis vaccine route on animal development and the efficiency of different routes
to protect birds against different Eimeria challenges were evaluated. 135 Isa Brown® birds were used in two experimental phases. In the first phase, the birds were distributed in three treatments: non-vaccinated,
vaccinated against coccidiosis by water and vaccinated by spray. In the second phase, these birds were
challenged separately with different eimeria species oocysts (E. maximum, E. acervulina, E. tenella and E.
necatrix). Weight gain, relative weight of Fabricius bursa, degrees of lesions in the intestines and counting
of oocysts in the coproparasitological examination were evaluated. As a result, in most cases, birds
challenged with different eimeria species and vaccinated against coccidiosis, by water or spray, showed
better physical conditions, mainly by: best weight gain and lower intestinal lesions scores, compared to the
birds challenged and non-vaccinated. Another interesting result refers to the different vaccine routes,
showing no significant difference regarding the effectiveness of the vaccine and the vaccine reaction in
