Cooled storage of semen from livestock animals (part I): boar, bull, and stallion.

Abstract: This review is part of the Festschrift in honor of Dr. Duane Garner and provides an overview of current techniques for cooled storage of semen from livestock animals. The first part describes the current state of the art of liquid semen preservation in boars, bulls, and stallions, including the diluents, use of additives, processing, temperature, and cooling of semen. The species-specific physiology and varying extents of cold shock sensitivity are taken into consideration. In addition, factors influencing the quality of cooled-stored semen are discussed. Methods, trends, and the most recent advances for improving sperm quality during cold-temperature storage are highlighted and their respective advantages and disadvantages are contrasted. There has been much progress in recent years regarding cold-temperature storage of boar sperm and there is great potential for a large-scale use to replace the current 17 °C temperature storage regime and the associated use of antibiotics in the future. For stallion sperm, there is an opposite trend away from previous low-temperature storage towards storage at higher temperatures to increase sperm viability and longevity. In bulls, liquid storage of sperm is mostly used in the seasonal dairy production systems of New Zealand and Ireland, but with further research focusing on shelf-live elongation of liquid preserved sperm, there is potential for an application in breeding programs worldwide.

The research article provides an overview of the current techniques for cooled storage of semen from boars, bulls, and stallions, aiming to improve sperm quality during cold-temperature storage.

Current Techniques for Cooled Storage

  • The article begins by offering an insight into the state-of-the-art techniques for liquid semen preservation in livestock animals such as boars, bulls, and stallions. Various elements factor into the process including diluents, use of additives, processing, temperature, and cooling of semen.
  • These techniques take into account the species-specific physiology and varying extents of cold shock sensitivity. Cold shock sensitivity refers to the damage that sperm might incur due to sudden temperature changes.

Factors Influencing Semen Quality During Cooled-Storage

  • The article also factors in influences that might affect the quality of cooled-stored semen. Factors influencing the quality could be varying from species to species.
  • It emphasizes that understanding these factors is key to developing effective strategies for semen preservation and eventual use in animal breeding.

Recent Advances and Trends

  • The paper provides information on the recent advances and trends in improving sperm quality during cold-temperature storage. It highlights the novel methods and trends, contrasting the advantages and disadvantages related to each one.
  • For instance, there has been progress in cold-temperature storage of boar sperm with potential for large-scale use to substitute the current 17 °C temperature storage regime. This could significantly reduce the use of antibiotics, potentially making the process more sustainable and cost-efficient.

Potential Application in Breeding Programs

  • The paper states that for stallion sperm, there is a trend away from previous low-temperature storage towards storage at higher temperatures to increase sperm viability and longevity. This implies that different storage strategies might be more appropriate for specific species.
  • Finally, in bulls, liquid storage of sperm is mostly used in the seasonal dairy production systems of New Zealand and Ireland. However, there is potential for a wider application in breeding programs worldwide, especially with further research focusing on shelf-live elongation of liquid preserved sperm.
