Evaluación de la Inseminación Intrauterino Profunda y Cervical en Cerdas

Abstract

At the Swine Production Unit of Cattle and Livestock Faculty of the ESPOCH the investigation on the evaluation of two types of artificial deep intrauterine and cervical insemination in sows was carried out. The total experimental units consisted of 16 York-Landrace sows which were distributed under a DCA in two treatments with eight replications each. From de results it can be concluded that the two treatments used upon analyzing the productive variables of the gestation satage did not show any significant difference (P< 0,05). As to the reproductive variables, the number of inseminations per sow both cervical and intrauterine was 1,25 times per conception, but in the cervical insemination the seminal dosage of 100ml was used with a concentration of 3x10° spermatozoa and in the intrauterine insemination the seminal dosage was 50ml with a concentration of 1,5x10° spermatozoa. The fertility percentage for the intrauterine Al and for the cervical Al was 75%. The conception percentage for the treatment with intrauterine Al 100% and for the cervical it was 87,5%. As to the productive variables in the lactation stage, there werw no significant differences (P<0,05). Upon applying the cervical Al 1,27 benefit-cost is obtained and applying the intrauterine Al it is 1,29. This is why it is recommended to use the intrauterine Al in intensive explotation.
