This article evaluated the pre-sowing treatment of seeds with electroozonation. A full factor experiment on the influence of the parameters of the technological process of electroozone treatment on the sowing qualities of maize seeds was carried out. Based on the experimental data, the effect of ozone concentration, treatment time and the time before sowing and after treatment on the germination ability, germination energy and growing energy of maize seeds was determined. According to the results of the study, the corresponding regression equations were calculated, graphical dependencies were constructed and method parameters for the pre-sowing treatment of maize seeds with ozone were determined. Ali tretiranje semena koruze z ozonom vpliva na njegovo kalitev in energijo kalivosti?Izvleček:Prispevek obravnava tretiranje semena koruze pred setvijo z elektroozoniranjem. V njem so predstavljeni rezultati faktorskega poskusa vpliva različnih dejavnikov tehnološkega procesa elektroozoniranja na dejavnike kakovosti semena koruze. V tej zvezi so predstavljeni vplivi koncentracije ozona, časa tretiranja z ozonom in časa pred setvijo (po tretiranju z ozonom) na odstotek kalitve, energijo kalivosti in energijo rasti semena koruze. Ob upoštevanju rezultatov raziskave so izračunane regresijske enačbe, izdelani grafični prikazi in predstavljeni ključni parametri semena koruze, tretiranega z ozonom pred setvijo.Ključne

This paper examines process efficiency problems in chlorella microphytic alga growth for quality feed of livestock and poultry. Ozone-air mixture for microphytic alga growth simulation and development is being suggested for use. Paper describes experimental research methods realization and some experimental equipment. Experimental plant to carry out research was built, which produces ozone-air mixture, with required ozone concentration, and delivers it to the tank that contains chlorella microphytic alga suspension. Moreover, equipment was selected in a way so it doesn’t interfere with the main technological process of microphytic alga growth, special attention was given to an energy saving effect of the equipment and technology in general. Experimental research results discussion demonstrates some statistical data and dependence curves, constructed using these results, and also derived on this basis regression equation. Research results were processed by the “Statistika 6.0” software, obtained results indicate sufficiently close correlation relationship between examined data. Some experimental work results were summarized in the conclusions, and substantial efficiency of the suggested technology was verified, which allows to reduce energy consumption in forage production.

This study aimed to develop a methodology to evaluate the protection of animals and people from the harmful effects of the farm’s microclimate and environment, taking into consideration the energy, economic and environmental indicators. To achieve this goal, the following were determined for 2019 for the eight countries which are the world leaders in the field of pig farming: the volumes of carbon dioxide pollution, ammonia, dust and manure, and the analytical dependencies between the feed consumption, pig productivity and the concentration of ammonia inside the farm. The weight gain of pigs reduced by 15% with an increase in the concentration of ammonia in the internal air of livestock houses to 20 mg/m3 , but the feed wastage increased by 12%. Mathematical models were developed to estimate the relationships between the feed consumption, pig productivity and the concentration of harmful gas (ammonia) which is one of the main parameters of the microclimate. The results will be used in making technical and technological decisions in the field of microclimate, cleaning and disposal of farm manure. Keywords: pig, farming, ecology, environment
