为了确定将PGF(2)α添加到人工授精(AI)的精液中是否能提高重复繁殖者雌性的生育力，进行了以下试验。在匈牙利一个有2000头母猪的大型室内生产单元中，667头重复繁殖的母猪被分成两组，处理如下：组1(n=322)，接受PGF(2)α，在人工授精前立即加入精液；组2(n=345)，接受人工授精(AI)和未处理精液。对受胎率、产仔率、后续总产仔数、产活仔数以及后续断奶至发情间隔时间进行了评估。受孕率和产仔率在前列腺素F(2)α处理组和未处理组之间有极显著差异(P<；0.001)。随后的总产仔数(P<；0.07)、活产仔数(P<；0.13)和随后的断奶至发情间隔(P<；0.23)没有显著差异。有理由认为，在人工授精中添加外源PGF(2)α可以提高受孕率和产仔率。(C)2002年，爱思唯尔科学公司出版。
In order to determine if PGF(2)alpha could improve fertility in repeat breeder females when added to semen used for artificial insemination (AI) the following trial was performed. In a large indoor Hungarian production unit of 2000 sows, 667 repeat breeding females were assigned to two groups and were treated as follows: Group 1 (n = 322), received PGF(2)alpha, added to the semen immediately before AI; Group 2 (n = 345), received AI with untreated semen. Conception rate, farrowing rate, subsequent total and live born litter size and subsequent weaning to estrus intervals were evaluated. Conception and farrowing rates revealed highly significant differences between the PGF(2)alpha-treated and nontreated animals (P < 0.001). Subsequent total born (P < 0.07), and live born litter size (P < 0.13), and subsequent weaning to estrus intervals (P < 0.23) showed no significant differences. It is reasonable to suggest that exogenous PGF(2)alpha added to AI semen improves conception and farrowing rates. (C) 2002 Published by Elsevier Science Inc.
