Resumo: Inbreeding depression as a consequence of mating between related animals, driven by reproductive biotechnologies and selection methods, affects traits of zootechnical interest, which causes economic and genetic diversity losses, in addition to limiting genetic progress. This review article exposes, through narrative review, causes and effects of inbreeding depression, with special attention to inbreeding coefficient estimates. From classical inbreeding coefficient calculated by pedigree to modern methodologies that indicate real levels of allele sharing, such as matrices of genomic relationships and homozygous races (ROH) are presented. The impact of inbreeding depression on traits related to production, health, fertility, and conformation is discussed in the context of different Holstein populations. It is concluded that much is known about inbreeding depression in Holstein populations; however, with the advent of genomics, and with it new approaches, the understanding of inbreeding depression can be expanded.

Este artículo de revisión, a través de la revisión narrativa, expone las causas y los efectos de la depresión consanguínea, con especial atención a las estimaciones del coeficiente de consanguinidad. Se presentan desde coeficiente de consanguinidad clásico calculado por pedigree hasta metodologías modernas que indican niveles reales de intercambio de alelos, como matrices de relaciones genómicas y razas de homocigosidad (ROH). El impacto de la depresión endogámica sobre los rasgos relacionados con la producción, la salud, la fertilidad y la conformación se discute en el contexto de diferentes poblaciones Holstein. Se concluye que se conoce mucho sobre la depresión consanguínea en poblaciones Holstein; sin embargo, con el advenimiento de la genómica, y con sus nuevos enfoques, se puede ampliar la comprensión de la depresión por consanguinidad.A depressão endogâmica como consequência do acasalamento entre animais aparentados, impulsionada por biotécnicas reprodutivas e métodos de seleção, afeta características de interesse zootécnico, o que causa perdas econômicas e de diversidade genética, além de limitar o progresso genético. Este artigo de revisão, por meio de revisão narrativa, expõe causas e efeitos da depressão endogâmica, com especial atenção às estimativas de coeficientes de endogamia. São apresentados desde o coeficiente clássico de endogamia calculado por pedigree, até metodologias modernas que indicam níveis reais de compartilhamento de alelos, como matrizes de relações genômicas e corridas de homozigose (ROH). O impacto da depressão endogâmica em características relacionadas à produção, saúde, fertilidade e conformação é discutido no contexto de diferentes populações da raça Holandesa. Conclui-se que muito se sabe a respeito da depressão endogâmica em populações da raça Holandesa; porém, com o advindo da genômica, e com isso novas abordagens, pode-se ampliar a compreensão da depressão endogâmica.Research, Society and Development2022-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3128810.33448/rsd-v11i8.31288Research, Society and Development; Vol. 11 No. 8; e58411831288Research, Society and Development; Vol. 11 Núm. 8; e58411831288Research, Society and Development; v. 11 n. 8; e584118312882525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/31288/26822Copyright (c) 2022 Fernando Jean Dijkinga; Vanessa Santos Sotomaior; Cristina Santos Sotomaiorhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDijkinga, Fernando JeanSotomaior, Vanessa SantosSotomaior, Cristina Santos2022-07-01T13:34:06Zoai:ojs.pkp.sfu.ca:article/31288Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:47:40.910116Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
