Abstract

Cryopreservation of cock semen includes a cooling/chilling phase to prolong its viability prior to freezing (Elomda et al., 2024). However, a previous study (Bernal et al., 2024) showed that fertility in Leghorn hens (LG) decreased from 48.2% with fresh semen (Hungarian Yellow breed, HA) undiluted (SP), to 3.7% with semen chilled at 5°C for one hour and diluted (SR). In a second phase, the use of fresh diluted (uncooled) semen increased fertility from 3.7% to 55.4%, while with SP it increased to 71.4%. This study examines whether the temperature of in-semination or the breed of the females
affects the loss of fertility with chilled semen.
