Swine reproduction for nonswine practitioners Part 1.

Reproductive physiology and management of the breeding herd

Abstract

In order to gain an understanding of swine reproduction, knowledge of basic physiology and breeding herd management parameters are necessary. Veterinarians need to be familiar with the estrous cycle, estrus synchronization, breeding management, and industry benchmarks. Data and information on when to intervene enables the practitioner to work with producers and managers in order to maintain swine reproduction. In the past 30 years, swine production systems have hired their own veterinarians and reproductive consultants. Although the commercial swine industry is primarily an integrated system that owns their own sows, boar collection facility, and other facilities involved in housing and breeding of swine, there is a growing population of pastured and niche-market operations requesting expert advice for breeding management of swine. With the majority of veterinary reproductive specialists with a working knowledge of swine being employed by the large swine integrated systems, it can be difficult for clients in these small operations to find a veterinarian to assist with their reproductive needs. This article will describe basic physiology and breeding management strategies to aid a nonswine practitioner to gain a working knowledge of swine reproduction.
