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. Fifty eight females were observed, 16 intercourses in captivity, 45 females arrived already fertilized from nature and 53 litters, resulting on the birth of 426 live neonates, 67 infertile egg masses, 18 stillborn neonates and 4 abnormal neonates. The intercourse period was from february to december and the births happened between february and may. From the two gestacional periods observed, the shortest one was 152 days and the longest 239. The average amount of live neonates per litter was 8,04. Among 323 neonates, 47,68% were males and 52,32% were females. During the first year of life, 75,71% of the females and 71,54% of the males died, and 2,31% of the females and 0,81% of the males reached the fifth year of life. |
