Resumo: | The mice are widely used in experimental research involving in vivo laboratory tests. It presents small size, easy handling, short reproductive period and easy domestic, which are characteristics that make it a good model, in addition to excellent compatibility with the human genome. The maintenance vivarium adopts different methods of reproduction, often using stranding systems at random, without making a technical analysis of reproductive efficiency. Thus, the present study aims to analyze the reproduction rates of BALB/c mice in different mating systems in the vivarium. Were used 28 BALB\c mice, 10 males and 18 females distributed among 03 different systems: permanent monogamous, permanent polygamous and temporary polygamous. Three generations were observed for each type of mating in the vivarium of the University Center of Anápolis, UniEvangélica. The permanent monogamous system was the most efficient in the number of pups used, both in birth rate and in weaning. The second generation showed better reproductive efficiency in all systems, in which animals reached greater sexual maturity. |

Presenta pequeño tamaño, fácil manejo, corto período de reproducción y fácil domesticación, son características que lo convierten en un buen modelo, además de una excelente compatibilidad con el genoma humano. Los bioterios de animales adoptan diferentes métodos de reproducción, a menudo utilizando sistemas de apareamiento al azar, sin hacer un análisis técnico de la eficiencia reproductiva. Por lo tanto, el presente estudio tiene como objetivo analizar la tasa de reproducción de ratones BALB/c en diferentes sistemas de apareamiento en el vivero. Se utilizaron 28 ratones de la cepa BALB\c, 10 machos y 18 hembras distribuidos en 03 sistemas diferentes: monógamos permanentes, polígamos permanentes y polígamos temporales. Se observaron tres generaciones para cada tipo de apareamiento en el vivero del Centro Universitario de Anápolis, UniEvangélica. El sistema monógamo permanente fue el más eficiente en cantidad de crías producidas, tanto en la tasa de natalidad como en el destete. La segunda generación mostró una mejor eficiencia reproductiva en todos los sistemas, en los que los animales alcanzaron una mayor madurez sexual.O camundongo é muito utilizado em pesquisas experimentais envolvendo teste laboratoriais in vivo. Apresenta pequeno porte, fácil manuseio, período reprodutivo curto e fácil domesticação são características que fazem dele um bom modelo, além de excelente compatibilidade com o genoma humano. Os biotérios adotam diferentes métodos de reprodução, muitas vezes usando sistemas de acasalamento de forma aleatória, sem fazer uma análise técnica da eficiência reprodutiva. Dessa forma, o presente estudo tem por objetivo analisar a taxa reprodutiva de camundongos BALB/c em diferentes sistemas de acasalamento no biotério. Foram utilizados 28 camundongos da linhagem BALB\c, sendo 10 machos e 18 fêmeas distribuídos entre 03 sistemas diferentes: monogâmico permanente, poligâmico permanente e poligâmico temporário. Foram observadas três gerações para cada tipo de acasalamento no biotério do Centro Universitário de Anápolis, UniEvangélica. O sistema monogâmico permanente foi o mais eficiente em quantidade de filhotes produzidos, tanto na taxa de natalidade quanto no desmame. A segunda geração apresentou melhor eficiência reprodutiva em todos os sistemas, na qual os animais atingiram maior maturidade sexual.Research, Society and Development2020-08-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/700810.33448/rsd-v9i9.7008Research, Society and Development; Vol. 9 No. 9; e112997008Research, Society and Development; Vol. 9 Núm. 9; e112997008Research, Society and Development; v. 9 n. 9; e1129970082525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/7008/6237Copyright (c) 2020 Maydson Vieira Silva, Valdomiro Souza dos Santos, Leandro Norberto da Silva Junior, Kelly Cristina Borges Tacon, Jalsi Tacon Arrudahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Maydson VieiraSantos, Valdomiro Souza dosSilva Junior, Leandro Norberto daTacon, Kelly Cristina BorgesArruda, Jalsi Tacon2020-09-18T01:42:11Zoai:ojs.pkp.sfu.ca:article/7008Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:53.680309Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
