Resumo: The incubatory of eggs has great importance in the production chain, since it is the supplier of the production chain. Thus, inefficiency in the incubatory affects the entire production chain. An experiment was performed in order to observe the effects of the broiler breeders and the heat loss of the eggs during the transfer from the hatchery to the hatcher on the yield of the incubation. Eggs from three ages: 26, 32 and 53 weeks of Cobb broiler breeders were incubated. These eggs were separated into two treatments: T0 as the control treatment, which complied with the procedures normally adopted by the incubator company and T1 which used a cooler to transport the eggs during the transfer. For both treatments the transfer took about 10 minutes in all the three repetitions. After the birth it was made the counting of the hatched chicks, of the unhatched eggs, the calculations of hatching and hatchability, the breaking of the unhatched eggs; all to determine at what time of the development the embryonary mortality took place, and the weight of the hatched chicks. The results obtained showed that the eggs of the 26-week breeders had higher infertility, which led to the lower hatching. Hatchability and mortality did not differ between the ages. The weight of the chicks differed in the three ages showing that the chicks of older breeders were heavier. Regarding the heat loss, the results showed that all the places evaluated had temperature and RH out of the recommended in the literature, characterizing the whole route as critical for the temperature control, and that the eggs of T1 suffered less heat loss in the transfers than the T0 eggs. However, the treatment using the cooler did not improve the hatchability indicators and chick weight for the studied transfer time.

Assim, a ineficiência no incubatório afeta todo o segmento. Foi realizado um experimento com o objetivo de observar os efeitos da idade da matriz pesada sobre o rendimento de incubação e a perda de calor dos ovos durante o trajeto da sala de incubação até o nascedouro. Foram incubados ovos de matrizes pesadas da linhagem Cobb de três idades: 26, 32 e 53 semanas. Esses ovos foram separados em dois tratamentos, sendo T0 o tratamento controle, que respeitou os procedimentos adotados normalmente pela empresa incubadora e T1, que utilizou uma caixa térmica para o transporte dos ovos durante a transferência. Para ambos os tratamentos a transferência durou cerca de 10 minutos em todas as três repetições. Após o nascimento foi realizada a contagem dos pintos nascidos, dos ovos não eclodidos, os cálculos de eclosão e eclodibilidade, a quebra dos ovos não eclodidos para averiguar em qual momento do desenvolvimento ocorreu mortalidade embrionária, e o peso dos pintos nascidos. Os resultados obtidos mostraram que os ovos de 26 semanas tiveram maior infertilidade, o que fez com que a eclosão se apresentasse menor, a eclodibilidade e mortalidade não foram diferentes entre as idades. O peso dos pintinhos diferiu nas três idades mostrando que os pintinhos de matrizes mais velhas são mais pesados. Quanto à perda de calor, os resultados mostraram que todos os locais avaliados possuem temperatura e UR fora do recomendado na literatura, caracterizando o trajeto todo como ponto crítico para controle da temperatura, e que os ovos de T1 sofreram menos perda de calor nas transferências que os ovos de T0. Todavia, o tratamento com caixa térmica não proporcionou melhoria nos indicadores de eclodibilidade e peso de pintinho, para o tempo de transferência estudado.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Estadual Paulista (Unesp)Pereira, Danilo Florentino [UNESP]Universidade Estadual Paulista (Unesp)Silva, Gabriela Fagundes da [UNESP]2016-04-07T18:09:24Z2016-04-07T18:09:24Z2016-02-19info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/11449/13782400087112933004099086P8porinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESP2023-11-11T06:14:41Zoai:repositorio.unesp.br:11449/137824Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462023-11-11T06:14:41Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
