Over the years, reproductive efficiency in the swine industry has focused on reducing the sperm cell number required per sow. Recent advances have included the identification of subfertile boars, new studies in extended semen quality control, new catheters and cannulas for intrauterine artificial insemination (AI), and fixed-time AI under commercial use. Therefore, it is essential to link field demands with scientific studies. In this review, we intend to discuss the current status of porcine AI, pointing out challenges and opportunities to improve reproductive efficiency.
多年来，猪繁殖效率的重点一直放在减少每头母猪所需的精子数量上。最近的进展包括鉴定出不育公猪、对延长精液质量控制的新研究、用于宫内人工授精 (AI) 的新导管和套管，以及商业使用的定时 AI。因此，将现场需求与科学研究联系起来至关重要。在这篇综述中，我们旨在讨论目前的猪 AI 状况，指出提高繁殖效率的挑战和机遇。
