摘要

本研究旨在探討自1995年起進行自交第三世代（3^(rd) intercross generation,簡稱I_3代）不分世代配種繁殖迄1999年完成選育期間，畜試黑豬之繁殖及生長性能。此期間共蒐集639胎次母豬繁殖性能及384頭公豬與1124頭女豬生長性能檢定資料。調查結果顯示，畜試黑豬母豬平均分娩窩仔數、出生死仔數、出生活仔數、三週齡活仔數及八週齡活仔數為9.9、2.3、7.6、7.1及6.6頭，3週與8週齡平均體重分別為4.63與13.4 kg，而3週與8週齡育成率則為93%與87%。平均分娩窩仔數以初產母豬的9.5頭最低，第三產次10.5頭最高，但由於出生死仔數隨著分娩窩仔數提高而增加，因此各產次之出生活仔數相近。在生長性能方面，自體重30至90 kg檢定期間，公豬的每日增重及修正達90 kg重日齡為0.639 kg/d及185日，顯著優於女豬的0.544 kg/d及206日，而公豬與女豬達90 kg重修正背脂厚度則為1.69與1.92 cm，差異顯著。

The study was conducted to investigate the reproductive and growth performance of TLRI Black Pig from 1995 to 1999. During this period, the reproductive performance of 639 litters, and the performance test of 384 boars and 1124 gilts from 30 to 90 kg body weight were recorded. The results showed that average litter size at birth (LS), born alive(LSA), litter size at 3 weeks of age and litter size at 8 weeks of age were 9.9, 7.6, 7.1 and 6.6, respectively. The body weight at 3 and 8 weeks of age were 4.63 and 13.4 ㎏ and survival rate were 93% and 87%, respectively. The LS for the first parity sow was the lowest (9.5 head) and was highest at the third parity (10.5 head ). Although the multiparous sow had larger LS, the dead piglets at birth was the highest at 3^(rd) parity (2.8 head). As a result, there was no significant diffrernce in LSA between primaparous and multiparous sows. The growth performance showed that there were significant difference (P ＜ 0.01) in daily gain, backfat thickness (BF) at 90 kg of body weight and age at 90 kg of body weight between sexes. The average daily gain of boar was 0.639 kg and was 0.544 kg for gilt. The age at 90 kg of body weight for boar was 185 days and 206 days for gilt. Boars had thinner BF than gilt (1.69 vs. 1.92 cm).
