Resumo: | Reproductive characteristics directly reflect on productive performance, as they determine the number of calves born annually and the interval between generations, thereby affecting the selection intensity. This allows for the determination of the most important economic variables that directly affect the production system. The present study is a literature review of somatotropic axis gene polymorphisms that are associated with reproductive functions in heifers and cows (Bos taurus taurus and Bos taurus indicus). The following characteristics were analyzed from the various studies reviewed: number of services per pregnancy (Nº services/pregnancy), age at first calving (AFC), calving interval (CI), and period of service calving conception interval (CCI). The research was conducted during the period from 2011 to 2021, and associations were found among all indicators of reproductive efficiency evaluated in heifers and cows, with 27 single nucleotide polymorphisms (SNPs): 18 in GHR, 5 in IGF-I, and 4 in STAT5A. This study revealed the relationships between SNPs and the reproductive efficiency indicators and demonstrated that molecular genetic techniques enhance the animal selection process, resulting in more profitable systems that are sustainable in the long term.Keywords: Molecular genetics; IGF-I; Animal reproduction; SNPs; STAT5A. |

Association between somatotropic axis gene polymorphisms and reproductive efficiency of bovine females: a reviewAssociação entre polimorfismos de genes do eixo somatotrópico e eficiência reprodutiva de fêmeas bovinas: revisão de literaturaReproductive characteristics directly reflect on productive performance, as they determine the number of calves born annually and the interval between generations, thereby affecting the selection intensity.

O presente estudo propõe realizar uma revisão de literatura de polimorfismos de genes do eixo somatotrópico associados a funções reprodutivas em novilhas e vacas (Bos taurus taurus e Bos taurus indicus), indicadas pelos índices: número de serviços por gestação (Nº serviços/gestação), idade ao primeiro parto (IPP), intervalo de partos (IP) e período de serviço, como também denominado de intervalo parto-concepção (IPC). As pesquisas encontradas durante o período de 2011 a 2021 demonstraram associações entre todos os indicadores de eficiência reprodutiva analisados de novilhas e vacas com 27 polimorfismos de nucleotídeo único (SNPs), sendo 18 em GHR, 5 em IGF-I e 4 em STAT5A. Dessa forma, este estudo mostrou relação entre os SNPs e os indicadores de eficiência reprodutiva, demonstrando que técnicas de genética molecular potencializam o processo de seleção dos animais, resultando em sistemas mais lucrativos e que se sustentam a longo prazo.Palavras-chave: Genética molecular; IGF-I; Reprodução animal; SNPs; STAT5A.Universidade Federal de Goiás2022-07-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfapplication/pdfapplication/pdfhttps://revistas.ufg.br/vet/article/view/72386Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 23 (2022): Continuous publicationCiência Animal Brasileira / Brazilian Animal Science; v. 23 (2022): Publicação contínua1809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporenghttps://revistas.ufg.br/vet/article/view/72386/38490https://revistas.ufg.br/vet/article/view/72386/38602https://revistas.ufg.br/vet/article/view/72386/38475https://revistas.ufg.br/vet/article/view/72386/38491https://revistas.ufg.br/vet/article/view/72386/38603https://revistas.ufg.br/vet/article/view/72386/38476Copyright (c) 2022 Ciência Animal Brasileira / Brazilian Animal Sciencehttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSantos Cruz, Geciele Maciel dos Santos Correa, Regianne Borges Macedo, Daralyns Luz Emerick, Lucas Fonseca de Castilho, Erick Nunes Rodrigues, Marília Danyelle 2023-03-23T18:43:54Zoai:ojs.revistas.ufg.br:article/72386Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:30.548017Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
