Resumo: Livestock in Brazil is still characterized by low zootechnical rates. Through these perspectives, research on reproductive biotechnologies has increased with the aim of reversing this scenario to ensure high reproductive efficiency in herds. The main biotechnologies applied to bovine reproduction include artificial insemination (AI), fixed-time artificial insemination (FTAI), superovulation (SOV) and embryo transfer (ET) and in vitro embryo production (IVP). The FTAI is highly recommended in the field due to its high rate of reproductive performance. To perform this technique, it’s necessary to use hormones such as estrogenic esters, prostaglandin, equine chorionic gonadotropin (eCG) and progesterone. Due to the long half-life of this hormone, the eCG can lead to the occurrence of multiple ovulations generating twin births. By this, the aim of this study was to report a case of a freemartin heifer, with patent urachus, from a triplet pregnancy resulting from artificial insemination. At first evaluation, the heifer presented inappetence, weight loss, cachexia, dehydration, prostration, pale oral and ocular mucosa, temperature of 39.5°C and diarrhea. In the evaluation of the extracavitary umbilical structures, it was noted that the urine was excreted through the vulva and the umbilicus and the site had an increase in volume. After a day in the hospital, the animal died. At necropsy, it was found the absence of female sexual organs such as uterus and ovaries and in the abdominal region, presence of fluid in the cavities (ascites and hydrothorax) were observed. The suspected death cause was ureter stenosis that led to uremia.

Bajo estas perspectivas, se ha incrementado la investigación en biotecnologías reproductivas con el objetivo de revertir esta situación. Las principales biotecnologías aplicadas a la reproducción bovina incluyen la inseminación artificial (IA), la inseminación artificial a tiempo fijo (IATF), la superovulación (SOV) asociada a la transferencia de embriones (TE) y la producción de embriones in vitro (PIV). Para realizar la IATF es necesario el uso de hormonas como estradiol, prostaglandinas, gonadotropina coriónica equina (eCG) y progestágenos. El eCG es una hormona utilizada en los protocolos y, debido a la larga vida media de esta hormona, el eCG puede provocar la aparición de ovulación múltiple que genere nacimientos de gemelos. El objetivo de este estudio fue reportar un caso de una vaquillona freemartin, con uraco permeable, proveniente de una gestación de trillizos producto de inseminación artificial mediante eCG. En la anamnesis, el ternero presentaba inapetencia, pérdida de peso, caquexia, deshidratación, postración, palidez de mucosa oral y ocular, temperatura de 39,5°C y diarrea. En la evaluación de las estructuras umbilicales extracavitarias, se observó que la orina se excretaba por la vulva y el ombligo y el sitio presentaba un aumento de volumen. Después de un día en el hospital, el animal murió. En la necropsia se observó ausencia de órganos sexuales femeninos como útero y ovarios y región abdominal con presencia de líquido en las cavidades (ascitis e hidrotórax). La muerte sospechosa fue estenosis del uréter que condujo a la uremia.A pecuária no Brasil ainda é caracterizada por baixos índices zootécnicos. Através destas perspectivas, as pesquisas com as biotecnologias reprodutivas têm aumentado com o intuito de reverter esse quadro. As principais biotécnicas aplicadas à reprodução bovina incluem a inseminação artificial (IA), inseminação artificial em tempo fixo (IATF), superovulação (SOV) associada a transferência de embriões (TE) e produção in vitro de embriões (PIVE). A IATF tem um alto índice de aplicação no campo devido a alta taxa de desempenho. Para executá-la é necessário o uso de hormônios como ésteres estrogênicos, prostaglandina, gonadotrofina coriônico equina (eCG) e progestágenos. A eCG é um hormônio utilizado nos protocolos, e, devido a meia-vida longa desse hormônio, a eCG pode levar a ocorrência de ovulações múltiplas gerando partos gemelares. Diante do exposto, o objetivo do trabalho foi relatar um caso de uma bezerra freemartin, com úraco patente, proveniente de gestação trigemelar advinda de uma inseminação artificial com uso de eCG. À anamnese a bezerra apresentava inapetência, emagrecimento, caquexia, desidratação, prostração, mucosas oral e ocular hipocoradas, temperatura de 39,5°C e diarreia. Na avaliação das estruturas umbilicais extracavitárias notou-se que a urina era excretada pela vulva e pelo umbigo e o local estava com aumento de volume. Após um dia internada, o animal foi a óbito. Na necropsia observou-se ausência de órgão sexuais femininos como útero e ovários e região abdominal com presença de líquido nas cavidades (ascite e hidrotórax). A suspeita da morte foi estenose do ureter que levou a um quadro de uremia.Research, Society and Development2022-05-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2984310.33448/rsd-v11i7.29843Research, Society and Development; Vol. 11 No. 7; e16311729843Research, Society and Development; Vol. 11 Núm. 7; e16311729843Research, Society and Development; v. 11 n. 7; e163117298432525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/29843/25737Copyright (c) 2022 Fernanda Alice Penha de Souza; César Vita Alves Romio; Miller Pereira Palhão; Paula Piccolo Maitanhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSouza, Fernanda Alice Penha de Romio, César Vita Alves Palhão, Miller Pereira Maitan, Paula Piccolo 2022-06-06T15:12:05Zoai:ojs.pkp.sfu.ca:article/29843Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:46:48.790739Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
