Data collected from 1982 to 1999, in Brasília, DF, Brazil, on 1102 head of Brazilian Bergamasca sheep were analyzed to obtain information on performance of the breed in the region. Average lambing interval was 337.94±109.4, but under continuous mating, the average lowered to 282.1days. Ewe lambing rate was 90.13%, frequency of twins 12.63%, number of triplets negligible and sex ratio 1:1. Lambing occurred in all months of the year. Age at first lambing was 588.58±65.31days. Average birth, 3, 6 and […]
