RESUMO
Bacteria continue to disrupt poultry production and can cause resistant and persistent yolk sac infections to prevention efforts, known as omphalitis, resulting in poultry death. This literature review aims to demonstrate how plant extracts can help combat omphalitis in poultry. The Google Scholar database served as a resource for retrieving pertinent literature covering a wide range of search terms relevant to the scope of the research. The search strategy involved a combination of terms such as antimicrobials, chick embryo, omphalitis, plant extracts, poultry nutrition, and sanitization. The potential of plant extracts in preventing or treating infections in poultry, especially omphalitis, is mainly due to their antibacterial and safety properties. Sanitization and direct delivery of plant extracts to the internal contents of eggs, feed, or water are cutting-edge interventions to reduce the bacterial load in eggs and poultry, minimizing infection rates. For example, these interventions may include advanced treatment technologies or precise delivery systems focused on disease prevention in poultry.
RESUMO
Poultry production is accompanied by the use of antimicrobial agents because no production step is free of microorganisms. In the absence of antimicrobial treatments with synthetic drugs, essential oils are among the most cited natural alternatives used to prevent and treat microbial contamination in poultry. Although there are several studies on the antimicrobial properties of essential oils, there is still no review that simultaneously compiles information on the leading antimicrobial role of essential oils from Citrus aurantifolia (CAEO), Ocimum basilicum (OBEO), and Allium sativum (ASEO) in poultry. Awareness of the antimicrobial role of these substances opens the door to encouraging their use in natural antimicrobial protocols and discouraging harmful synthetics in poultry. This review aimed to compile information on applying CAEO, OBEO, and ASEO as antimicrobials in poultry farming. The available literature suggests that these essential oils can proportionately align with the poultry industry's demands for microbiologically safe food products.
