Diferentes desinfetantes sobre a contaminação e desempenho da incubação de ovos de avestruz

From the moment of laying, eggs come into contact with microorganisms that adhere to the shelland disinfection is the process that reduces contamination by preventing them from penetrating the shell and invading the egg's internal content, however, different active principles can result in effects several. The objective was to evaluate the efficiency of different active principles in the disinfection of ostrich eggs on contamination andthe productive indexes of incubation. 16 eggs were used, distributed in two disinfectant active ingredients (quaternary ammonia and formaldehyde) in a completely randomized design with 8 replications. Contamination of the eggshell was evaluated by microbiological analysis on the surface of the eggshell after disinfection. The productive indexes of the incubation were evaluated by means of the index of weight loss of the egg (%), mortality rate (%), embryology (%) and hatchability (%). There was no significant difference (p> 0.05) between the active ingredients used in terms of disinfection capacity and productive indexes of incubation. It is concluded that bothactive ingredients are efficient in the disinfection of eggs, ensuring the control of contamination on the surface of the egg shell during the storage and incubation processes, in addition to not affecting the parameters of the incubation.
