Resumen de Precocidade e desempenho em corridas de cavalos Puro-Sangue Inglês brasileiros
Genetic and phenotypic correlations among age at the first race (F) and racetrack performance traits (number of victories (NV), number of placements in top 5 (N5), percentage of victories (PV), percentage of placementes in top 5 (P5), and number of starts (NS)) were estimated for 1.138 Brazilian Thoroughbred using MTDFREML software. The results indicates that horses with a high genetic merit for NV and PV were those with a low genetic potential for F. Phenotypically, animals with greater NS and N5 were those with lower F.
