Abstract

The objective of this study was to compare pregnancy rates in domestic cats using fresh semen for the bilateral intrauterine insemination (BIUI) method and the novel uterine body insemination (UBI) method. Queens received a single injection of equine chorionic gonadotropin (eCG) (200 IU; IM) to induce ovarian follicular development and, after 83 h, an injection of human chorionic gonadotropin (hCG) (100 IU; IM) for final oocyte maturation and ovulation induction. Thirty-four hours after hCG administration, 3 × 106 fresh spermatozoa were used for insemination by the BIUI (n = 8 queens) or by the UBI (n = 7 queens) techniques respectively. Pregnancy rates were 75.00% (6/8) by BIUI and 42.85% (3/7) by the UBI method. The mean litter size was 3.0 ± 0.86 for the BIUI, and 2.0 ± 1.0 for the UBI method. Spontaneous abortion occurred on day 35 of pregnancy in one queen following the UBI method. Our findings showed that the BIUI of queens with fresh semen resulted in higher pregnancy rates than the novel UBI method; also, acceptable pregnancy rates were achieved following BIUI with fresh semen in the domestic cat.

家猫新鲜精液人工授精两种方法的效果比较

本研究的目的是比较使用新鲜精液进行双侧宫内受精（BIUI）方法和新型子宫体受精（UBI）方法的家猫的妊娠率。皇后区接受单次注射马绒毛膜促性腺激素（eCG）（200 IU；IM）以诱导卵巢卵泡发育，并在83小时后注射人绒毛膜促卵泡激素（hCG）（100 IU；IM）用于最终卵母细胞成熟和排卵诱导。hCG给药34小时后，分别用3×106个新鲜精子通过BIUI（n=8个皇后）或UBI（n=7个皇后）技术进行受精。BIUI法妊娠率75.00%（6/8），UBI法妊娠率42.85%（3/7）。BIUI法的平均产仔数为3.0±0.86，UBI法为2.0±1.0。在UBI方法之后，一位皇后在妊娠第35天发生了自然流产。我们的研究结果表明，使用新鲜精液的女王的BIUI比新的UBI方法导致更高的妊娠率；此外，在家猫中使用新鲜精液进行BIUI后，获得了可接受的妊娠率。
