Sanitary-hygienic treatment of fodder for chickens with ozone-air mixture

Abstract

In the natural environment, the most dangerous contaminants of feed are mycotoxins, which negatively affect the health and productivity of animals. Ozone is a powerful oxidizer that has strong disinfectant properties, is capable of destroying microorganisms while being environmentally friendly and safe. The effect of the ozone-air mixture used for the decontamination of the feed on its nutritional and sanitary quality was evaluated. The studies were conducted at the poultry farm of Kodyma LLC of the Kodyma District of Odesa region in a poultry house with a total livestock of 5 000 heads on laying hens of Isabraun cross. Used a corona discharge ozonizer, the technological process of detoxification of feed included purging the ozone-air mixture of feed in the hopper. Two feed processing modes with different durations (t = 10 min and 60 min) and ozone concentration in the mixtures used (C = 0.1 g/m 3 and 1 g/m 3) were selected. In the experimental samples of feed was determined: the number of mesophilic aerobic and optional anaerobic microorganisms, the presence of bacteria paratyphoid group (salmonella), the presence of enteropathogenic strains of E. coli, the number of micromycetes. Determination of the microflora of the test samples was carried out by conventional methods. It is established that the ozone-air mixture does not affect the nutritional and total energy value of the compound feed. Microbiological studies have found that the total number of microorganisms in the compound feed treated with the ozone-air mixture was significantly lower than in the conventional compound feed. It was found that as a result of the ozone-air mixture the number of mesophilic aerobic and optional anaerobic microorganisms in the compound feed decreased by 99.9 %, micromycetes (fungi and yeast) were not detected. The use of environmentally friendly energy-saving technologies, including the processing of the ozone-air mixture for decontamination during storage, processing of grain, for the production of grain products and compound feeds is relevant. Ozone exerts an activating effect on protein feed structures, enhancing the absorption of amino acids by proteins. The productivity of laying hens is greatly improved.

Using Ultraviolet Irradiation to Disinfectcompound Feeds

“…To date, some methods of chemical treatment of feed have been proposed to improve its sanitary condition in order to prevent spoilage and increase safety for animals: ozonation on poultry farms [7] and the use of sodium formate [8], but ozonation is not used industrially, and the effect of sodium formate is not sufficiently studied.…”
