Abstract

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.
