SUMMARY: Maternal and growth traits of a maternal rabbit line (line H), founded selecting on hyperprolificacy, were studied. Line H was compared to line V, a maternal rabbit line with high prolificacy. There were not differences between the two lines for live litter weight at birth when the number of born alive was used as a covariate. Thus, the high prolificacy of line H has not implied any reduction in the viability of the kids at birth or during lactation. Litter weight at 21 days after parturition is superior in line H, which implies a better milk production for its does. The results in that character show how the difference with line V increases with parity order. Additionally individual growth traits were compared between the two lines. Line H showed a higher individual weaning weight than line V, in agreement of its higher maternal abilities also showed with litter weight at 21 days. There were not differences between the two lines for individual weight at the end of the fattening period or individual average daily gain during this period.
