The Environmental Impact of Pig Farming

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, environmen

Microwave installation for accelerating the process of salting the food products

This article contains a description of the developed installation for salting and heat treatment of raw meat, which allows accelerate the salting process due to electrophysical effects. To provide the population with quality products from small-sized meat raw materials with reduced energy consumption, it is necessary to create rational conditions for their processing, ensuring the intensification of production processes based on the use of non-traditional types of energy carriers, and in particular electromagnetic waves of ultrahigh frequency. When raw materials are introduced into the resonator chamber in the developed installation, a traveling component appears in the standing wave, which transfers energy from the source to the raw material, which ensures its heating
