Ítem Acceso Abierto Evaluación de consanguinidad y su efecto sobre caracteres productivos en un hato caprino lechero.(Universidad Católica de Cuenca., 2022) Correa Tenesaca , Daysi Yessenia; Maldonado Cornejo, Manuel Esteban; 0150091817Consanguinity is a growing phenomenon in a population where there is no blood refreshment in the group. The objective of this research was to use the evaluation of the effect of consanguinity on quantitative parameters of production and management of a dairy herd of Saneen goats as an indicator in genetic enhancement. This was done with the records of 300 production animals in a dairy herd in the parish of Yaruquì-Quito. The Pedigree Viewer software was used to calculate the consanguinity coefficient. Previously, technical and production control visits were planned to validate and verify the processes. To increase the reliability, only 61% of the herd with all the productive and pedigree records were tested, where 13.5% of the herd showed consanguinity. However, when comparing the changes in production (liters) of the herd concerning the different degrees of consanguinity (0 vs. ≥ 3.12%, ≥ 6.25%, ≥ 12.5%), there were no differences between the groups (p ≥ 0.05), both in terms of lactation as well as in the different lactation thirds. This study was a diagnostic, management, and planning tool to establish a genetic enhancement program for this and any productive herd based on the current circumstances of the country, where there are restrictions regarding the introduction of new genetic material, making it essential to manage property registrations correctly. Keywords: Genetic enhancement, Saneen goats, planning, lactation.
