The analyzed sources of variation were litter size, sex, rank of lactation, year and season of kiddings. Age at first kidding averaged 17.2±3.1 months and the mean kidding interval was 8.5±1.2 months. Litter size (LS) at birth, during suckling and at weaning were 2.25, 2.05 and 1.95 kids per doe, respectively. LS at birth ranged from 1.7 kids at first to 2.4 kids at sixth kidding. Body weights at birth (BW) and at weaning (WW) (for an average age of 82±15 days) were 1.73±0.34 and 7.75±1.76kg, respectively. BW and WW were 10% and 8% higher for males than for females, respectively. Both traits were 15% higher (P<0.01) for single than for multiple kids. Daily weight gain from 10 to 30 and from 30 to 70 days of age were 84.3±25.9 and 65.7±24.1g, respectively. Daily weight gain from 10 to 30 days of age (data adjusted for birthweight) varied from 95g for single kids to less than 70g for multiples (P<0.01), and from 91g for males to 86g for females, respectively (P<0.01). Kids' preweaning mortality averaged 13.6%, 60% of which occurred from birth to 15 days post-partum. It increased with LS and was 5% higher (P<0.01) for males than for females.
