Applying Huxley equation to different components of genital tract, maximum uterine relative growth rate was achieved when live weight ranged 15 - 20 kg. Likewise, duplication of uterine weight at 120 and 330 days of age coincided with a high degree of folicular differentiation and appearance of the first corpus luteum, respectively. This latter event was also associated to a significant increase in serum progestagens concentration. In conclusion, it seems likely that puberty in female capybaras is achieved when they are 10 to 12 months old. 4aHydrochoerus Hydrochaeris 4aCapybara 4aHembra 4aPubertad 4aReproducción 4aCrecimiento 4aMamiferos 4aSeparatas0 tRevista de la Facultad de Agronomía de la Universidad Central de Venezuelag(1993)w211473 a(AGROP)40275217209 aAR-ReUNNbspacAR-ReUNNeaacr2
