studeing the effectiveness of the alcohol and water Propolis extract as a disinfectant for hatching eggs and compare it with the conventional method

الملخص

disinfection hatching eggs is a basic process and the most widespread method in field is fumigation with formaldehyde which is classified by the World Health Organization as a toxic substance that causes many health problems. As a means of finding a healthy alternative, 400 eggs were collected from breeder's hatching eggs then divided into four groups The first group consisted of 150 eggs divided into three groups (A₁, B₁ and C₁) with 50 eggs in each group and disinfection with the alcohol propolis extract of the concentrations (5%, 10% and 15%)   ,respectively. The second group consisted of 150 eggs divided into three groups (A₂, B₂, and C₂) with 50 eggs in each group and disinfection with the aqueous propolis extract of the concentrations (5%, 10%; 15%), respectively, and the third group is made up of 50 egg disinfected by fumigation with formaldehyde and the fourth group is made up of 50 egg left without disinfection as a witness. The results showed significant differences between treatments at 5% significance among the various disinfectant groups. The efficacy of the alcohol extract, especially at the concentration of 15%, was superior to the effectiveness of formaldehyde as a disinfectant. The water extract did not compete with formaldehyde, But approached its effectiveness at 15% concentration.
