Abstract：
The optimization of processes associated with artificial insemination (AI) is of great importance for the success of the pig industry. Over the last two decades, great reproductive performance has been achieved, making further significant progress limited. Optimizing the AI program, however, is essential to the pig industry\'s sustainability. Thus, the aim is not only to reduce the number of sperm cells used per estrous sow but also to improve some practical management in sow farms and boar studs to transform the high reproductive performance to a more efficient program. As productivity is mainly influenced by the number of inseminated sows, guaranteeing a constant breeding group and with healthy animals is paramount. In the AI studs, all management must ensure conditions to the health of the boars. Some strategies have been proposed and discussed to achieve these targets. A constant flow of high-quality and well-managed breeding groups, quality control of semen doses produced, more reliable technology in the laboratory routine, removal of less fertile boars, the use of intrauterine AI, the use of a single AI with control of estrus and ovulation (fixed-time AI), estrus detection based on artificial intelligence technologies, and optimization regarding the use of semen doses from high genetic-indexed boars are some strategies in which improvement is sought. In addition to these new approaches, we must revisit the processes used in boar studs, semen delivery network, and sow farm management for a more efficient AI program. This review discusses the challenges and opportunities in adopting some technologies to achieve satisfactory reproductive performance and efficiency.
摘要：
与人工授精（AI）相关的过程的优化对于养猪业的成功至关重要。在过去的二十年里，取得了很好的繁殖性能，取得进一步重大进展有限。优化AI程序，然而,对养猪业的可持续性至关重要。因此，目的不仅是减少每头发情母猪使用的精子细胞数量，而且还改善母猪养殖场和公猪螺柱的一些实际管理，以将高繁殖性能转变为更有效的程序。由于生产力主要受授精母猪数量的影响，保证一个恒定的繁殖群体和健康的动物是至关重要的。在AI螺柱中，所有管理层都必须确保公猪的健康条件。已经提出并讨论了实现这些目标的一些策略。源源不断的优质,管理良好的养殖群体,生产的精液剂量的质量控制，实验室常规中更可靠的技术，去除肥沃较少的公猪，使用子宫内AI，使用控制发情和排卵的单一人工智能(固定时间人工智能)，基于人工智能技术的发情检测,和优化使用高遗传指数公猪的精液剂量是一些寻求改善的策略。除了这些新方法，我们必须重新审视公猪螺柱中使用的过程，精液递送网络，并播种农场管理，以实现更高效的人工智能计划。这篇综述讨论了采用一些技术来实现令人满意的生殖性能和效率的挑战和机遇。
