This study evaluated the effect of false mounts (FM) on quality of frozen-thawed semen in beef bulls. Five mature Brahman bulls at the Standard Semen Production Center in Thailand were subjected to semen collection. Overall, 60 ejaculates were collected over a 12-week period of which 30 were collected without, and another 30 were collected using FM. A range of quality parameters of fresh, pre-frozen, and frozen-thawed semen were evaluated. Use of FM resulted in significant improvement of most parameters of fresh semen except progressive motility and sperm viability. The quality parameters of pre-frozen and frozen-thawed semen also significantly improved with FM. Use of FM significantly improved the viability of frozen-thawed semen, possibly indicating the protective effect of seminal plasma proteins.
本研究评估了假阴道（FM）对肉牛冻融精液质量的影响。泰国标准精液生产中心的 5 头成熟婆罗门公牛接受了精液采集。在 12 周的时间内，共采集了 60 次精液，其中 30 次未使用 FM，另外 30 次使用 FM。评估了新鲜、预冻和冻融精液的一系列质量参数。除了前向运动和精子活力外，使用 FM 显著改善了新鲜精液的大多数参数。使用 FM 还显著改善了预冻和冻融精液的质量参数。FM 显著提高了冻融精液的活力，这可能表明精液蛋白质具有保护作用。
