Dynamics of variability of the animal heart rhythm and its correlation with economic parameters and age

For several years, strengthened state support caused a situation, when domestic livestock has reached the European level on many qualitative and quantitative parameters. At the same time, dairy cattle breeding remains one of the most problematic branches. Intense loads during economic use lead to a decrease in vital energy and functional and physiological reserves of the body. The problem of reducing the economic characteristics of cows with age is relevant. In this regard, many questions related to the need to preserve these functional reserves arise and the latter can be studied using non-invasive methods. One of such methods is cardiointervalometry of heart rate variability. The method allows evaluating the physiological state of the animal, which can be influenced by both exogenous and endogenous factors

Use of electromagnetic fields of extremely high frequency band for productivity improvement of cereal crops

At present, in connection with rapid changes in climatic conditions, it is important to find the ways for preserving required productivity of farming crops.Microwave technology allows us to improve seed germination ability by their preplanting processing, which is one of the factors indicating an increase in productivity of farming crops.Here, we focus mainly on designing the models for managing biological objects and systems, at choosing parameters of electromagnetic fields of the extreme high frequencies, and at finding optimal modes for the pre-planting seed processing. Results of theoretical and experimental studies presented here confirm the possibility of controlling productivity of crops by their processing by electromagnetic fields of extremely high frequencies
