Otimização do processo de incubação industrial de ovos férteis de matrizes de perus

Abstract

This dissertation Brazil is the third largest producer and second largest exporter of turkey meat. Even with all the prestige and importance of the supply chain, there are few scientific studies related to it, especially when it comes to egg incubation. The management of arrays in the field is of utmost importance to the results of a company, as well as the handling of eggs and poults a day in hatcheries. This paper deals with the incubation process fertile eggs from turkeys matrices order to obtain the best results for industrial hatcheries. In the experiment carried out to study the effect of three treatments (control,3 hours and 12 hours) preheating eggs before storage technique which is an alternative to suppress the negative effects of prolonged storage. In parallel we were evaluated two periods of storage (5 and 12 days) eggs, which practice is ever more utilized in hatcheries for production and standardization issues flow of lots. The variables analyzed were all hatching egg weight loss until the time of transfer (PPOT), egg weight ratio and weight poults (RPO/RPP), eliminated poults, embryonic mortality incubation period and total mortality. Among the preheat treatment, it was observed that the 12 hours had a higher percentage hatching, a lower percentage of poults eliminated and reduced mortality of the third and fourth week of incubation. Regarding the storage period, the 5 day period provided significant gains for hatching percentage of variables, mortality in the final phase and total mortality when compared to the stock of 12 days. The pPot and RPO / RPP results variables maintained within the industry desired percentage, showing that they were not negatively affected by any of the preheat treatment, or by storage periods.
