Development of a zinc asparaginate-based disinfectant for disinfection of hatching eggs

Abstract

Based on the results of the previous studies of bactericidal and fungicidal properties of zinc asparaginate, a new disinfectant for the incubation of eggs has been developed. The use of the zinc asparaginate-based disinfectant for treatment of hatching eggs is recommended in the concentration of 3 %. The dosage for treating hatching eggs is 0.2 ml of the solution, which corresponds to 0.6 mg of zinc per egg. The preparation has passed the experimental storage periods test; the shelf life of this product is 2 years. Two experiments were performed: the proof-of-concept experiment with 3 repetitions, and the production one. During the period of incubation, the research was performed for detecting the growth of bacterial cultures. It has been noted that zinc asparaginate can inhibit bacterial growth for 6 days, which has an advantage to formaldehyde. The yield of the conditioned broiler chickens of the "Cobb-500" cross in the production experiment in the experimental group was 5.6 % higher than that in the reference group, where chickens were treated with a 37 % aqueous solution of formaldehyde.
