Identification of human factors to achieve pregnancy in artificially inseminated sows

Abstract

Because pork meat is in high demand, pig farms implement artificial insemination to produce a greater proportion of this protein; however, it is valuable to take into account many aspects at the time of heat detection and timely inseminate to achieve production goals. In this article we present the progress of a bibliographical review on the repeated identification of errors or oversights, incurred by human factors, that do not favor the pregnancy of the sows inseminated with any of the different techniques or in the procedures carried out for the collection and evaluation of the semen. For this, various types of documents (mainly articles and degree theses) have been considered in university repositories, in indexed journals and in recognized databases. In these reviews, it is verified that the personnel in charge of carrying out each one of the processes to inseminate must not only have a deep and updated knowledge about the characteristics of the reproducers or about the analysis of porcine sperm, but must also know about the different stages of the sow's estrus and the optimal moment to inseminate; important factors to achieve the expected pregnancy and increase reproductive rates on farms. In this sense, the decrease in the percentage of artificially inseminated pregnant sows is attributed to failures directly related to this process, ignorance of specific factors in each of the steps to inseminate and insufficient preparation of the people who perform it; For this reason, it is important that they have a high level of training that allows them to implement and develop the different insemination techniques to improve and increase pig production
