中文摘要 | Hal-l843是豬緊迫基因的單核□突變點所在位置,核□鹼基若為C代表正常,若 為T則為突變者,故緊迫基因的Hal-1843遺傳型有CC、CT和TT三種。自美國進口的65頭 盤 克夏種女豬於六月齡左右運抵臺灣省畜產試驗所,在核心種豬場飼養繁殖,本研究探討H .-1843遺傳型對盤克夏種母豬達兩歲齡繁殖性狀之影響。Hal-1843遺傳型為CC、CT和TT 者 分別有31、23和1頭。初產前發生淬死的女豬,在CC型和CT型女豬分別有9.7%(3/31)和 21.7%(5/Z3)。具TT型的一頭母豬耒有發情配種記錄,CT型母豬有52.2%(12/23)產下第 一胎,而CC型母豬則已有64.5%(20/31)產下第一胎。CT型母豬的初產日齡為498±20天, 較CC型者(438±18天)延遲了60天(P<0.05)。初產窩仔數和活仔數並未受到母豬Hal- 1843遺傳型的影響。CC型和CT型母豬的初產窩仔數分別為7.06和6.75頭,而CC型和CT 型母 豬的初產活仔數分別為5.90和5.75頭。具CC和CT型的初產母豬發生淬死的比率分別為10. 0%(2/30)和16.7%(2/12)。兩歲齡時已產下第二胎的百分率,在CC和CT型母豬分別為 55.6%(10/18)和.40.0%(4/10),但有離乳仔豬的比率為80%(8/10)和50%(2/4)。綜合 上述結果,Hal-1843突變基因會影響到盤克夏種母豬的初產日齡和再次配種受孕率。 |
英文摘要 | Hal-1843 represents a single nucleotide mutation point on the nucleotide sequence of porcine stress gene. When the nucleotide 1843 is C, the porcine stress gene is a normal gene. The nucleotide 1843 is T for mutant gene and there are three genotypes: CC, CT and TT represented for Hal-1843 genotypes. In this study, 55 gilts were imported from USA and they arrived at Taiwan Livestock Research Institute at approximately six months of age. There were 31, 23 and 1 gilts with CC, CT and TT of Hal-1843 genotype, respectively. Effects of Hal-1843 genotype on maternal traits were determined when gilts were two years old. The TT gilt did not have any mating records when she was two years old. The percentages of gilts that died suddenly were 9.7% (3/31) and 21.7% (5/23) in the CC and CT genotype groups, respectively. At two years of age, 52.2% (12/23) of CT gilts had their first litter and so did 64.5% (20/31) of CC gilts. Comparison on the age at first parity between CT and CC gilts showed 498±20 days for CT gilts which was 60 days later than that of CC gilts (438±18 days) (P<0.05). Both maternal traits, litter size in total and number of born alive, at first parity, were not different between Hal-1843 genotypes. CC sows had 7.06 piglets in total and 5.90 live piglets at birth as compared to CT sows which had 6.75 piglets in total and 5.75 live piglets at birth. 10.0% (2/20) and 16.7% (2/12) of primiparous sows died suddenly which were with CC and CT genotype, respectively. Percentages of primiparous sows having the second parity at two years old were 55.6% (10/18) and 40.0% (4/10) for CC and CT sows, respectively. But percentages of sows-at second parity with their own weaned piglets decreased to 80% (8/10) and 50% (2/4) in the CC and CT genotype groups, respectively. In summary, the mutant Hal-1843 gene affected the age at first parity and the percentage of re-parturition of Berkshire sows. |
