Pregnancy loss in the female bovine and strategies to improve efficiency in assisted reproductive programs: Animal Health and Production
In artificial insemination (AI) programs, repeated estrus and embryonic (EM) and fetal losses are important causes of low reproductive efficiency in hot climates. This literature review aims to show the causes and strategies to decrease pregnancy losses in cows. In cattle, the fertilization rate is...

| description | In artificial insemination (AI) programs, repeated estrus and embryonic (EM) and fetal losses are important causes of low reproductive efficiency in hot climates. This literature review aims to show the causes and strategies to decrease pregnancy losses in cows. In cattle, the fertilization rate is high and occurs in approximately 75 to 90% of the inseminated females. Embryonic losses occur in more than 25% of the services and the highest proportion of them occurs between 15 to 17 days after service and six weeks after the beginning of pregnancy. Biotechnical procedures used to prevent repeat estrus and embryonic and fetal mortality include the use of exogenous hormones including progesterone, estrogens, growth hormone, humanchorionic gonadotropin, hormone releasing factors and recombinant alpha interferon to enhance corpus luteum functions and inhibit the mechanism of luteolysis. Other procedures include the application of various biotechnical estrus synchronization and resynchronization procedures to improve the efficiency of AI services and correct low estrus detection efficiency. Feeding supplementation with unsaturated fat and antioxidants and management measures to reduce the impact of heat stress. These procedures can contribute to improve fertility of cattle in hot climates. |

Esta revisión bibliográfica tiene como objetivo mostrar las causas y estrategias para disminuir las pérdidas de la preñez en la vaca. En el ganado bovino, la tasa de fertilización es alta y ocurre aproximadamente entre el 75 al 90% de las hembras inseminadas. Las mermas embrionarias se producen en más del 25% de los servicios y de ellas la mayor proporción se produce, entre 15 a 17 días del servicio y las seis semanas de inicio de la preñez. Los procedimientos biotécnicas utilizados para prevenir las repeticiones del celo y la mortalidad embrionaria y fetal tales como: el uso de hormonas exógenos que incluyen la progesterona, los estrógenos, la hormona del crecimiento, la gonadotropina coriónica humana, los factores de liberación hormonal y el alfa interferón recombinante con el fin de potenciar las funciones del cuerpo lúteo e inhibir el mecanismo de la luteólisis. Otros procedimientos incluyen la aplicación de diversos procedimientos biotécnicas de sincronización y resincronización del celo para mejorar la eficiencia de los servicios de IA y corregir la baja eficiencia en la detección del celo. La suplementación alimentaría con grasa no saturada y sustancias antioxidantes y medidas de manejo para reducir el impacto del estrés del calor. Estos procedimientos pueden contribuir a mejorar la fertilidad del ganado bovino en climas cálidos.Nos programas de inseminação artificial (IA), os cios repetidos, as perdas embrionárias (EM) e fetais são causas importantes de baixa eficiência reprodutiva em climas quentes. Esta revisão da literatura tem como objetivo mostrar as causas e as estratégias para reduzir as perdas de gestação em vacas. Nos bovinos, a taxa de fertilização é elevada e ocorre em cerca de 75 a 90% das fêmeas inseminadas. As perdas embrionárias ocorrem em mais de 25% das cobrições e a maior proporção dessas perdas ocorre entre 15 a 17 dias após a cobrição e seis semanas após o início da gestação. Os procedimentos biotécnicos utilizados para evitar a repetição do cio e a mortalidade embrionária e fetal incluem: a utilização de hormonas exógenas, incluindo progesterona, estrogénios, hormona do crescimento, gonadotropina coriónica humana, factores de libertação de hormonas e interferão alfa recombinante, a fim de melhorar as funções do corpo lúteo e inibir o mecanismo de luteólise. Outros procedimentos incluem a aplicação de vários procedimentos biotécnicos de sincronização e ressincronização do estro para melhorar a eficiência dos serviços de IA e corrigir a baixa eficiência de deteção do estro. Suplementação alimentar com gorduras insaturadas e substâncias antioxidantes e medidas de gestão para reduzir o impacto do stress térmico. Estes procedimentos podem contribuir para melhorar a fertilidade dos bovinos em climas quentes.Portoviejo: Universidad Técnica de Manabí2024-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/zipapplication/zipapplication/epub+zipapplication/pdfhttps://revistas.utm.edu.ec/index.php/latecnica/article/view/547210.33936/latecnica.v14i1.5472La Técnica.
