Resumo: | The present study aimed at evaluating the different storage periods of eggs from free-range hens on incubation variables. Treatments were composed according to the following egg storage periods: 1 to 5 days, 6 to 10 days, 11 to 15 days and 16 to 20 days. The variables analyzed were egg weight loss, embryonic mortality, hatchability rate and chick weight at birth. The experimental design was completely randomized. The variables related to weight were subjected to analysis of variance and the Scott-Knott test at 5% probability. Egg weight and chick weight at birth were not influenced by egg storage time; however, egg weight loss during storage was greater (P <0.05) from 11 days of storage. Egg weight loss during incubation was greater (P <0.05) in the storage period from 1 to 5 days. The embryonic mortality rate reached 52% in the period from 15 to 20 days, while the hatchability rate decreased in this period, reaching 47.6%. Storage for periods over 16 days should be avoided, as there is a marked reduction in hatchability rate. |

Se establecieron los tratamientos según el período de almacenamiento de los huevos, que fueron de: 1 a 5 días, 6 a 10 días, 11 a 15 días y de 16 a 20 días. Las variables analizadas fueron la pérdida de peso de los huevos, mortalidad embrionaria, nacimiento y peso de los pollitos al nacer. El diseño experimental fue completamente al azar. Las variables relacionadas al peso fueron sometidas a análisis de varianza y a la prueba de Scott-Knott, a 5% de probabilidad. No hubo influencia del período de almacenamiento en el peso de los huevos y de los pollitos al nacer, sin embargo, la pérdida de peso en el almacenamiento fue más grande (P<0,05) a partir de día 11. La pérdida de peso de los huevos durante la incubación fue mayor (P<0,05) en el período de 1 a 5 días de almacenamiento. La tasa de mortalidad embrionaria llegó a 52% para el período de 15 a 20 días de almacenamiento, mientras, la tasa de nacimiento, en ese período, cayó, llegando a 47,6%. Se deben evitar almacenamientos superiores a 16 días, pues hay una reducción acentuada en los nacimientos.O objetivo desse estudo foi avaliar os diferentes períodos de estocagem de ovos de galinhas caipiras, sobre as variáveis de incubação. Os tratamentos foram formados conforme o período de estocagem dos ovos, que foram de: 1 a 5 dias, 6 a 10 dias, 11 a 15 dias e de 16 a 20 dias. As variáveis analisadas foram a perda de peso dos ovos, mortalidade embrionária, eclodibilidade e peso dos pintinhos ao nascimento. O delineamento experimental foi o inteiramente casualizado. As variáveis relacionadas ao peso foram submetidas à análise de variância e ao Teste Scott-Knott a 5% de probabilidade. O peso dos ovos, e o peso dos pintinhos ao nascimento não foi influenciado pelo período de estocagem, no entanto, a perda de peso na estocagem foi maior (P<0,05) a partir do 11 dias de estocagem. A perda peso dos ovos durante a incubação foi maior (P<0,05) no período de 1 a 5 dias de estocagem. A taxa de mortalidade embrionária chegou a 52% para o período de 15 a 20 dias de estocagem, enquanto, a taxa de eclodibilidade despencou para este período, chegando a 47,6%. Estocagens superiores a 16 dias devem ser evitadas, pois há uma redução acentuada na eclodibilidade.Research, Society and Development2020-07-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/648710.33448/rsd-v9i8.6487Research, Society and Development; Vol. 9 No. 8; e742986487Research, Society and Development; Vol. 9 Núm. 8; e742986487Research, Society and Development; v. 9 n. 8; e7429864872525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/6487/10915Copyright (c) 2020 Rafaela Dalmolin Menezes, Carlos Alexandre Oelke, Bruno Neutzling Fraga, Patricia Rossi, Janaina Rossetto, Patrícia Messa Alonso, Luis Wagner Gomes Quevedohttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMenezes, Rafaela DalmolinOelke, Carlos AlexandreFraga, Bruno Neutzling Rossi, PatriciaRossetto, JanainaAlonso, Patrícia MessaQuevedo, Luis Wagner Gomes2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/6487Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:36.135697Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
