Bacteria and Boar Semen Storage: Progress and Challenges.

Area of Science:

• Animal Science
• Veterinary Medicine
• Reproductive Biology

Background:

• Artificial insemination with chilled boar semen is standard in porcine breeding.
• Antibiotic supplementation is used during semen storage to prevent bacterial contamination.
• Bacterial contamination poses risks to sperm quality, functionality, and sow health.

Purpose of the Study:

• To detail the negative effects of bacterial contamination on boar semen during cold storage.
• To review current antibiotic alternatives for semen preservation.
• To address the issue of antibiotic resistance in swine reproduction.

Main Methods:

• Literature review of studies on boar semen storage and bacterial contamination.
• Analysis of the impact of bacterial load on sperm parameters.
• Evaluation of emerging antimicrobial strategies and non-antibiotic alternatives.

Main Results:

• Bacterial contamination significantly reduces sperm motility, viability, and fertility.
• Antibiotic use contributes to the development of antibiotic resistance genes.
• Several non-antibiotic methods show promise in controlling bacterial growth in semen.

Conclusions:

• Reducing antibiotic use in boar semen storage is crucial for animal health and combating resistance.
• Alternative antimicrobial strategies are essential for sustainable porcine breeding.
• Further research is needed to optimize non-antibiotic methods for boar semen preservation.
