Óleo essencial de canela na desinfecção de ovos férteis

Abstract

This work aimed to analyze the effect of using cinnamon essential oil (Cinnamomum sp) in the disinfection of fertile eggs, evaluating hatchability, chick quality and embryodiagnosis. It sought the development and improvement of methods for poultry farming and society itself. Since using cinnamon essential oil (Cinnamomum sp) to disinfect eggs represents an innovation that can minimize the use of products with greater toxicity, contributing to the maintenance of consumer health. 768 COBB® eggs were evaluated, divided into four treatments with 192 eggs each, cinnamon essential oil (Cinnamomum sp) was applied by spraying in treatments 1 (treatment with oil in washed eggs) and 3 (treatment with oil in sanded eggs), totaling 384 eggs that came into contact with cinnamon essential oil (Cinnamomumsp) and 384 eggs divided into treatment 2 (treatment without oil in washed eggs) and 4 (treatment without oil in sanded eggs) that were without oil cinnamon essential oil (Cinnamomum sp). The eggs went through the disinfection process on the farms, and as soon as they arrived at the hatchery, they were classified and incubated. In the pre-incubation process, essential oil of cinnamon (Cinnamomum sp) was applied by spraying in an amount of 5 ml, diluted in 1 ml of Polysorbate 80 together with 100 ml of distilled water at a concentration of 5%, after In this process, the eggs remained for about 30 to 60 minutes to expose the essential oil of cinnamon (Cinnamomum sp) in contact with the egg shell. Then the eggs were incubated and on the nineteenth day after transfer they were taken to the hatching room where they were housed for 48 hours. evaluated chick quality. After collecting the data, the statistical analyzes were carried out using the Scott-Kontt method and with the results we were able to observe in the embryodiagnosis that the treatments did not have statistical differences in themselves. However, in terms of hatchability and chick quality, treatment 1 (treatment with oil in washed eggs) was the only one that obtained a lower effect compared to the use of cinnamon essential oil, while treatments 2, 3 and 4 did not show statistical differences. each other. When treatments 3 (treatment with oil in sanded eggs) and treatment 4 (treatment without oil in sanded eggs) were compared, no significant difference was obtained either, for this reason it can be concluded that the use of cinnamon essential oil in the disinfection of fertile eggs can be used as an alternative product in relation to the use of formaldehyde, because in three treatments we noticed a significantly better effect in relation to only one treatment, which had an average considered lower, but when we look at the economic side within the hatcheries, with the As a result of this work, cinnamon essential oil is not indicated.
