| dc.description | Artificial insemination is a first-generation reproductive biotechnology that consists of the introduction of semen into the female's genital organs without the intervention of the male, facilitating fertilization and production of an offspring. The objective of this document was to investigate the methods of artificial insemination in the porcine species. The bibliographic review was carried out in published articles, scientific journals, books and virtual libraries. Studies carried out on 20 nulliparous sows of the Duroc breed, with post-cervical insemination and according to the time of expression of estrus, the sows were served twice with variable insemination intervals (ITEI) of 8 hours (h) (8:00 a.m. – 16:00 pm) and 16 h (16:00 pm – 8:00 am) with SC from two Pietrain boars, using 10 straws of 0.5 mL each with 600 x 106 sperm; in the first, they presented a conception rate was 80% (16/20); while the number of piglets born per litter corresponded to 5.75 ± 2.33 and 4.13 ± 2.08, respectively. highlighting that most of the piglets appeared high body weight at birth, leading to difficult deliveries and increased mortality. In conclusion, it is confirmed that post-cervical artificial insemination can be applied in nulliparous sows and obtain good conception rates with the use of cryopreserved semen. However, litter size is greatly affected. | es_ES |

| dc.description.abstract | La inseminación artificial es una biotecnología de la reproducción de primera generación que consiste en la introducción del semen en los órganos genitales de la hembra sin la intervención del macho, facilitando la fecundación y producción de una cría. El presente documento tuvo como objetivo investigar los métodos de inseminación artificial en la especie porcina. La revisión bibliográfica se realizó en artículos publicados, revistas científicas, libros y en bibliotecas virtuales. Estudios realizados en 20 cerdas multíparas de la raza Duroc, con inseminación poscervical y de acuerdo a la hora de expresión de celo, las cerdas fueron servidas dos veces con intervalos variables de inseminación (ITEI) de 8 horas (h) (8:00 am – 16:00 pm) y 16 h (16:00 pm – 8:00 am) con SC de dos verracos Pietrain, utilizando 10 pajuelas de 0,5 mL cada una con 600 x 106 espermatozoides; en la primera.presentaron una Tasa de concepción fue de 80% (16/20); mientras que el numero de lechones nacidos por camada correspondieron a 5,75 ± 2,33 y 4,13 ± 2,08, respectivamente. destacando que la mayoría de los lechones presentaron alto peso corporal al nacimiento propiciando partos dificultosos y aumento de la mortalidad. En conclusión, se confirma que se puede aplicar la inseminación artificial pos cervical en cerdas multíparas y obtener buenas tasas de concepción con el uso de Semen Crio preservado. Sin embargo, el tamaño de la camada se afecta considerablemente. | es_ES |
