ИСПОЛЬЗОВАНИЕ ОЗОНА ДЛЯ СТИМУЛИРОВАНИЯ ЭМБРИОНАЛЬНОГО РАЗВИТИЯ ПЕРЕПЕЛЯТ В ПЕРИОД ИНКУБАЦИИ

Abstract

Most often in industrial poultry farming formaldehyde vapors are used for preincubation processing of eggs, which has a toxic effect both on staff and on the development of embryos during incubation. In this regard, still more attention is paid to the search for environmentally friendly methods of processing eggs and stimulating embryos. Objective: to establish the effect of pre-incubation treatment of eggs with ozone on embryo development rates. The research was carried out at “OOO MIP EcoDom”, which operated at the Gorsky State Agrarian University from 2016 to 2019. Quail eggs of the Estonian breed were taken for the study; they were divided into 4 groups: the control one was processed in the traditional way (formaldehyde vapor per 1 m3 of the volume of a special chamber 35 ml of 37% formalin solution plus 20 ml of water plus 20 g of potassium permanganate); for the first experimental group the duration of ozonation was 10 minutes; the second it was 20 minutes and for the third – 30 minutes. The ozone concentration was 10 mg/m3 . In the course of incubation on the 5th, 10th and 15th day, in accordance with the established standards, biological control was performed. The studies of the morphology of the experimental bird showed that during the period of hatching the chickens of all experimental groups were well developed. They had well-defined blood vessels, the entire body was covered with down. The limbs were pressed to the eggshell, and the head was near the air chamber. Deviations from the norms and pathologies were not found. Basing on the above, it can be concluded that the ozonation of hatching eggs does not cause side effects and positively affects the further development of chicks. It was found that the mass of quail embryos, incubated eggs, subjected to pre-incubation treatment with ozone lasting 20 minutes and a concentration of 10 mg/m3 was significantly higher than the corresponding parameter in the control at 6-, 10- and 15-day olds by 12.20%; 21.46% and 12.75%, respectively. The same pattern was observed in terms of embryo lengths.
