Management practices to improve reproductive efficiency of the gilt will enable more efficient introduction of gilts into the breeding herd. In this paper, puberty and continuation of regular estrous cycles, ovulation rate and embryonic/fetal survival are the aspects of gilt reproductive efficiency to be considered. Within each of these reproductive areas, factors such as genetics, environment, nutrition, etc., are reviewed and general management practices are proposed. Because of the diversity of swine production systems, the proposed management practices to improve gilt reproductive performance must be considered and incorporated into individual herds on a trial basis.
提高后备母猪繁殖效率的管理措施将有助于更高效地将后备母猪引入繁殖猪群。本文将探讨后备母猪繁殖效率的几个方面，包括初情期和规律发情周期的维持、排卵率以及胚胎/胎儿存活率。在这些繁殖领域中，我们将审视遗传、环境、营养等因素，并提出一般性的管理措施。由于养猪生产系统的多样性，提高后备母猪繁殖性能的建议管理措施必须经过试验，并根据各个猪群的情况加以应用。
