Resumo: 	The reproduction of Bothrops jararaca (Wied, 1824) in captivity in ordened to determine the intercourse period, births, number of neonates, proportion of males and females per litter were performed between 1989 and 1999.

The average amount of live neonates per litter was 8,04. Among 323 neonates, 47,68% were males and 52,32% were females.
