Description:	The aim of the present study was to evaluate pregnancy rates and reproductive characteristics of three different lineages: Antiga (A), Nova (N) and Cruzada (C) of Canchim bulls. The bulls (n=27; 52.0±2.7 months; 674.7±18.6 kg) were kept on pasture, from 2014 to 2017, comprising the breeding seasons. Prior to entry in the breeding season, the bulls underwent breeding soundness evaluation. Bulls were annually challenged to mount an average of 40 Canchim cows (n=990). In order to evaluate the pregnancy rate, the cows were submitted to transrectal ultrasonography at the end of the season. After andrological evaluation, each bull was classified as Superior or Intermediary, according its seminal quality. Animals of the N and C lineages had higher pregnancy rates (P<0.05). Bulls classified as Superiors presented higher pregnancy rates, compared to the data of the population evaluated (P<0.05).
