[Cryopreservation trial with semen of purebred Arabian and Haflinger stallions in the Turkish national stud in Karacabey].

This study reports on a cryopreservation trial performed on the semen of Arabian and Haflinger stallions from the Turkish national stud in Karacabey, as part of a German-Turkish university partnership. The study aimed to determine the effects of deep freezing on semen quality, using a variation of the Makrotüb method for semen freezing.

Methodology

• The trial involved the use of stallion semen from Arabian and Haflinger breeds, partaking in deep freezing preservation procedure.
• The study employed a modification of the Makrotüb method, which is deep freezing technique used for semen preservation.

Findings

• The researchers found that the characteristics of the fresh semen of the Arab stallions aligned with what is traditionally cited within international literature, suggesting normal semen health in these specimens.
• However, the semen data observed from the Haflinger stallions were significantly lower than that of the Arab stallions. This could potentially indicate an incomplete adaptation process for the imported Haflinger population in the Turkish national stud.
• Due to local circumstances, no trials were conducted using the Al protocol.

Implications

• The results of the study provide insight into the semen quality of different horse breeds under preservation conditions. This information can be beneficial in artificial reproduction within these horse breeds.
• The findings also raise questions about the adaptation process of imported horse populations, specifically the Haflinger breed within the context of this study. Further research could be beneficial to identifying the causes behind the observed differences in semen quality.
