Resumo: | The objective of this study was to evaluate the influence of different incubation temperatures (IT) on the post-hatching reproductive characteristics of Japanese quails (Coturnix coturnix japônica). A total of 1332 fertile eggs were incubated at different temperatures: 36.0, 37.5 and 39.0 ° C. After hatching, the birds were transferred to breeding cages until 35 days of age and, later, to production cages in groups of nine females and three males. The experimental design was in randomized blocks (repetition over time) with three treatments and six repetitions, with the experimental unit represented by two cages. IT did not influence (P> 0.05) birth weight and hatching window, however, greater hatchability (P <0.05) was observed in eggs incubated at 37.5 ° C. There was no effect (P> 0.05) of the TI on the relative weight of the organs at 35 and 60 days of age and on the growth curve of the males. In females, body weight at maturity of growth was higher (P <0.01) when the IT was 39.0 ° C. The anatomy of the testicles and semen characteristics were not influenced (P> 0.05) by IT, except for sperm viability, which was higher (P <0.05) when temperatures of 37.5 and 39.0 oC were used. There was no effect (P <0.05) of the IT on the fertility of the eggs and also on the morphological characteristics of the female reproductive organs. However, younger age at the first egg and younger age at which birds reached 80% were observed (P <0.05) when the IT was 39.0 ° C. There was no effect (P> 0.05) of the IT on egg quality, except for the yolk height, which was higher (P <0.01) in the ITs of 36.0 and 39.0 ° C. It is concluded that the temperature of 37.5 ° C should be used during the incubation of Japanese quail eggs. |

Um total de 1332 ovos férteis foram incubados em diferentes temperaturas: 36,0, 37,5 e 39,0 °C. Após a eclosão, as aves foram transferidas para gaiolas de criação até os 35 dias de idade e, posteriormente, para gaiolas de produção em grupos de nove fêmeas e três machos. O delineamento experimental foi em blocos casualizados (repetição no tempo) com três tratamentos e seis repetições, sendo a unidade experimental representada por duas gaiolas. A TI não influenciou (P>0,05) o peso ao nascimento e a janela de eclosão, porém, maior eclodibilidade foi observada (P<0,05) em ovos incubados a 37,5 °C. Não houve efeito (P>0,05) das TI no peso relativo dos órgãos aos 35 e aos 60 dias de idade e na curva de crescimento dos machos. Nas fêmeas, o peso corporal na maturidade do crescimento foi maior (P<0,01) quando a TI foi de 39,0 °C. A anatomia dos testículos e as características do sêmen não foram influenciadas (P>0,05) pelas TI, exceto para a viabilidade espermática, que foi maior (P<0,05) quando as temperaturas de 37,5 e a 39,0 oC foram utilizadas. Não houve efeito (P<0,05) da TI sobre a fertilidade dos ovos e também sobre as características morfológicas dos órgãos reprodutivos das fêmeas. Entretanto, menor idade ao primeiro ovo e menor idade em que as aves atingiram 80% foram observados (P<0,05) quando a TI foi de 39,0°C. Não houve efeito (P>0,05) da TI sobre a qualidade dos ovos, exceto para a altura da gema, que foi maior (P<0,01) nas TI de 36,0 e 39,0°C. Conclui-se que a temperatura de 37,5 °C deve ser utilizada durante a incubação de ovos de codornas japonesas.Universidade Federal de LavrasPrograma de Pós-Graduação em ZootecniaUFLAbrasilDepartamento de ZootecniaZangeronimo, Márcio GilbertoFassani, Édison JoséAlvarenga, Renata RibeiroFassani, Édison JoséPeixoto, Juliano VogasMiranda, José RafaelGeraldo, AdrianoSouza, Alexandre Vinhas de2021-10-15T18:06:15Z2021-10-15T18:06:15Z2021-10-152021-04-27info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfSOUZA, A.
