Resumo: The aim was to conduct a literature review on the estrus detection and its interference on the reproductive efficiency of dairy cattle. Efficient and accurate estrus detection of cattle and artificial insemination in an assertive time are essential to increase pregnancy rate, estrus detection rate, and consequently good reproductive efficiency. Methods of estrus detection that are widely used on farms do not have good rates.  This is because the physiological and behavioral changes of the animals, as well as the period of the duration of the estrus cycle, are being expressed in low intensity and short duration. In addition, they are very variable and difficult to measure. Thus, it is of utmost importance to use electronic methods to improve estrus detection.

La detección eficiente y precisa del celo y la inseminación artificial en un tiempo asertivo son esenciales para aumentar la tasa de detección de celo y, en consecuencia, la tasa de preñez de las vacas. Los métodos de detección de celo que se utilizan ampliamente en las granjas no muestran buenos índices. Esto se debe a que los cambios fisiológicos y de comportamiento de los animales, así como el período de duración del ciclo estral, se expresan en baja intensidad y corta duración. Además, son muy variables y difíciles de medir. Por lo tanto, es de suma importancia utilizar métodos electrónicos para mejorar la detección de celo.Objetivou-se realizar uma revisão de literatura sobre a detecção de estro e sua interferência sobre o desempenho reprodutivo de rebanhos leiteiros. A detecção eficiente e precisa do estro e a realização da inseminação artificial em um tempo assertivo é fundamental para aumentar a taxa de detecção de estro e, consequentemente a taxa de prenhez das vacas. Os métodos de detecção do estro que são amplamente utilizados nas fazendas não têm apresentando bons índices. Isto porque as mudanças fisiológicas e comportamentais dos animais, assim como o período da duração do ciclo estral, estão sendo expressas em baixa intensidade e curta duração. Além disso, são muito variáveis e de difícil mensuração. Desta forma, é de suma importância a utilização de métodos eletrônicos para melhorar a detecção do estro.Research, Society and Development2020-05-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/406310.33448/rsd-v9i7.4063Research, Society and Development; Vol. 9 No. 7; e243974063Research, Society and Development; Vol. 9 Núm. 7; e243974063Research, Society and Development; v. 9 n. 7; e2439740632525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/4063/3403Copyright (c) 2020 Letícia Ribeiro Marquesinfo:eu-repo/semantics/openAccessMarques, Letícia RibeiroAlmeida, João Vitor NogueiraMarques, Thaisa CamposGuimarães, Kátia CylenePaim, Tiago do PradoLeão, Karen Martins2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/4063Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:02.888044Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
