Results of a 12 month study of traditional guinea-pig production in the western highlands of Cameroon are reported. The mean age of guinea-pigs (Cavia porcellus L.) at first parturition, kidding interval and litter size at birth were 126.30 +/- 10.40 d, 64.8 +/- 1.70 d and 1.63 +/- 0.26 kids respectively. The annual reproductive rate was 9.18 kids/breeding doe while the doe post-partum weight was 530 g. Mean body weights at birth, presumed weaning (21 d) and 15 weeks of age were 78.36 +/- 3.20, 147.51 +/- 8.10 and 418.88 +/- 32 g respectively. Type of birth and sex had a significant effect on body weight at all ages. Birth weight dropped significantly from 83.88 +/- 2.87 g for singles to 81.57 +/- 3.40 g for twins, 74.25 +/- 2.39 g for triplets and 73.75 +/- 4.12 g for quadruplets. These differences were maintained to maturity (15 weeks). Males were generally heavier than females. Mortality rates were relatively high among kids: 24% at birth, 39% at 3 weeks and 40% at 15 weeks. Productivity indices were 0.827 kg of young weaned per doe per year, 1560 g of young weaned per kg of doe per year and 2.52 kg of young weaned per kg metabolic weight (kg 0.75) of female per year.
报告了在喀麦隆西部高地对传统豚鼠养殖进行的为期12个月的研究结果。豚鼠（豚鼠属）首次分娩时的平均年龄、产仔间隔和出生时的窝仔数分别为126.30±10.40天、64.8±1.70天和1.63±0.26只幼仔。年繁殖率为每只繁殖母羊9.18只幼仔，而母羊产后体重为530克。出生时、假定断奶时（21天）和15周龄时的平均体重分别为78.36±3.20、147.51±8.10和418.88±32克。出生类型和性别在所有年龄段对体重都有显著影响。单胎出生体重从83.88±2.87克显著下降到双胎的81.57±3.40克、三胎的74.25±2.39克和四胎的73.75±4.12克。这些差异一直保持到成熟（15周）。雄性通常比雌性重。幼仔的死亡率相对较高：出生时为24%，3周时为39%，15周时为40%。生产效率指标为每只母羊每年断奶幼仔0.827千克、每千克母羊每年断奶幼仔1560克以及每千克雌性代谢体重（千克0.75）每年断奶幼仔2.52千克。
