The objective of this study is to determine the existence of seronegative subpopulations against these 3 reproductive diseases in 21 Brazilian farms which are vaccinating routinely with a commercial trivalent vaccine (parvovirus, erysipela and leptospira).

prevalence of seronegative breeders for SE and PPV in Brazilian
farms, as previous studies described.
