ÓLEO ESSENCIAL DE CINNAMOMUM VERUM E ORIGANUM VULGARE NA SANITIZAÇÃO DE OVOS INCUBÁVEIS

Abstract

The growth of broiler chicken production leads to conditions that require proper management in the hatchery to avoid environmental issues due to waste generation. This is because the high productivity of broiler chicks results from the efficient work of hatcheries and consequent profitability of the business. It depends on the application and knowledge of factors influencing broiler chick production, with each stage requiring meticulous management, standardization, and positive results. For example, the percentage of chicks born with a high standard. As a strategy in the poultry industry, the cleaning of fertile eggs is employed to reduce the microbial load on the eggshells. This chapter presents a study about the management of fertile eggs from selection on the farm to incubation and chick hatching, depicting each phase and emphasizing the potential use of natural sanitizing alternatives, such as essential oils, and the methods of sanitizing fertile eggs used. For this purpose, a literature review methodology was applied through bibliographic research, where the most recent period was analyzed. Articles, theses, and dissertations from various databases were used to compile this review. It is concluded that formaldehyde is the most used conventional sanitizer due to its easy application. However, when it encounters water, forming the solid paraformaldehyde, the procedure becomes unhealthy due to its toxic potential to workers, which leads to health issues ranging from respiratory problems to cancer. It also has a negative environmental impact, contaminating soil and water. As a result, alternative sanitization with natural products, such as essential oils, has been widely studied in poultry farming, considering their sanitizing potential as a safe option in poultry production. The aim is to ensure food safety and improve working conditions for those involved in chick production, focusing on sustainability and providing healthy, environmentally viable products. Therefore, it was observed that more research is still needed to consolidate the use of natural sanitizers in hatchery routines.
