Resumo: | Knowledge of the embryonic development of species such as quail is important for our understanding of its production and reproduction. Quail provides a practical solution to the animal protein shortage problem in developing countries and is an excellent alternative to chicken (Shanaway, 1994). This study evaluated quail embryonic viability by comparing the main morphological changes that occur over the development in a homemade incubator with previous data; the incubator was built using easily accessible and low-cost materials, which allows small producers and communities to develop quail farms as an activity to increase income or even produce a source of animal protein for the community in the Brazilian Amazon region. The homemade incubator measured 40 cm × 42 cm × 32 cm and was constructed with wooden boards, a digital thermostat, and an incandescent lamp. A total of 24 fertile eggs were incubated at a temperature of 37.5 °C and 60% relative humidity; age “0” was set at the start of incubation. Two eggs were opened on each day of development, starting from day 5 to day 16 of incubation. After gently opening the eggs, the embryos were removed, separated from the placenta and amniotic fluid, washed with running water, and weighed on a digital scale (SHIMADZU AUY 220 brand and UNI BLOC model). Crown-rump length and other measurements were performed with a digital caliper and the morphological structures were observed using a stereomicroscope (NOVA brand and NOVA ZTX-E model). All eggs opened contained live embryos, indicating that the homemade incubator temperature, relative humidity, and manual turning were adequate to maintain the quail's viability. The morphometric data of the embryos at different developmental time points were similar to those described in the literature. Embryos weighed 0.0069 g at day 5 and 4.7863 g at day 16, and the crown-rump length (CRL) means were 0.368 cm and 3.657 cm, respectively. Weight and CRL increased by 0.434 g and 2.593 cm per day of incubation, respectively. In conclusion, after 16 days of incubation in a homemade incubator, the embryos presented all phases of the development cycle, with appropriate development of weight and height based on the days of incubation without anomaly or external interference. These findings demonstrate that the homemade incubator does not alter the embryonic development of quail embryos in the Brazilian Amazon region. |

A codorna fornece uma solução prática para o problema de escassez de proteína animal nos países em desenvolvimento e é uma excelente alternativa ao frango (Shanaway, 1994). Este estudo avaliou a viabilidade embrionária de codornas comparando as principais alterações morfológicas que ocorrem ao longo do desenvolvimento em uma incubadora caseira com dados anteriores; a incubadora foi construída com materiais de fácil acesso e baixo custo, o que permite que pequenos produtores e comunidades desenvolvam criações de codornas como atividade para aumentar a renda ou mesmo produzir uma fonte de proteína animal para comunidades da Amazônia brasileira. A incubadora caseira media 40 cm × 42 cm × 32 cm e foi construída com tábuas de madeira, termostato digital e lâmpada incandescente. Um total de 24 ovos férteis foram incubados a uma temperatura de 37,5 °C e 60% de umidade relativa; idade “0” foi definida no início da incubação. Dois ovos foram abertos a cada dia de desenvolvimento, começando do dia 5 ao dia 16 de incubação. Após a abertura cuidadosa dos ovos, os embriões foram retirados, separados da placenta e do líquido amniótico, lavados em água corrente e pesados em balança digital (marca SHIMADZU AUY 220 e modelo UNI BLOC). O comprimento cabeça-cauda e demais medidas foram realizadas com paquímetro digital e as estruturas morfológicas foram observadas com auxílio de estereomicroscópio (marca NOVA e modelo NOVA ZTX-E). Todos os ovos abertos continham embriões vivos, indicando que a temperatura da incubadora caseira, a umidade relativa e a viragem manual foram adequadas para manter a viabilidade das codornas. Os dados morfométricos dos embriões em diferentes momentos do desenvolvimento foram semelhantes aos descritos na literatura. Os embriões pesaram 0,0069 g no dia 5 e 4,7863 g no dia 16, e as médias do comprimento cabeça-cauda (CRL) foram de 0,368 cm e 3,657 cm, respectivamente. Peso e CRL aumentaram 0,434 g e 2,593 cm por dia de incubação, respectivamente. Em conclusão, após 16 dias de incubação em incubadora caseira, os embriões apresentaram todas as fases do ciclo de desenvolvimento, com desenvolvimento adequado de peso e altura com base nos dias de incubação sem anomalia ou interferência externa. Esses achados demonstram que a incubadora caseira não altera o desenvolvimento embrionário de embriões de codorna na Amazônia brasileira.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2023-01-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdftext/xmlhttps://rbmv.org/BJVM/article/view/127610.29374/2527-2179.bjvm004322Brazilian Journal of Veterinary Medicine; Vol. 45 (2023); e004322Revista Brasileira de Medicina Veterinária; v. 45 (2023); e0043222527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVenghttps://rbmv.org/BJVM/article/view/1276/1298https://rbmv.org/BJVM/article/view/1276/1302Copyright (c) 2023 Adriana Caroprezo Morini, Graciene Conceição dos Santos, Rosana Tapajos de Oliveira, Thaiza Santos Farias, Angelo Abaal Lisboa Batista, Alanna do Socorro Lima da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMorini, Adriana Caroprezodos Santos, Graciene Conceiçãode Oliveira, Rosana TapajosFarias, Thaiza SantosBatista, Angelo Abaal Lisboada Silva, Alanna do Socorro Lima2023-01-05T17:35:29Zoai:ojs.rbmv.org:article/1276Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2023-01-05T17:35:29Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false |
