摘要：

Data on reproductive performance were collected from over 255 female goats located on seven islands in five South Pacific countries for three breeding seasons (1984-1986). Data were used to determine the breeding patterns of goats in the various countries. Gestation length for Fiji and Western Samoa averaged 149.5 and 151.3 days, respectively. Litter size ranged between 1 and 3 kids for all does in all five countries. Litter size (LS) was related to doe age (A): LS = 1.8402 + 0.0002A (R2 = 0.07; P < 0.0001) and parity (P): LS = 1.2290 + 0.1214P (R2 = 0.13; P < 0.0001). Birth weight (BW) ranged between 1 and 6 kg and could be described by a multiple regression equation: BW = 2.7564 - 0.3316LS + 0.1863BP (R2 = 0.18; P < 0.0001), where BP is the period of breeding. Kidding interval of goats ranged between a minimum of 166 in Tonga to a maximum of 1100 days in Fiji. Ranges of kidding percentage and sex ratio of kids (F/M+F%) were 138.8-149.0% and 42-61%, respectively. © 1990.
