Aerospace Technologies in Grazing Livestock

Remote monitoring systems find practical application in various branches of science. Recent research shows the interest and practical significance of the agricultural sector in the use of aerospace technologies to assess the quality of agricultural land. The purpose of this work was to identify the relationship between the NDVI (Normalized Difference Vegetation Index), obtained by remote sensing, and the nutritional value of natural pastures. The research was carried out in an arid region of the Stavropol Territory on the territory of a breeding farm for breeding and raising fine-wool sheep of the Dzhalginsky Merino breed. To obtain data obtained remotely, a unique scientific installation (UNU) “Vega-Science”, which is part of the Center for Collective Use “IKI-Monitoring”, was used. The chemical composition of pasture feed was carried out in the laboratory of the Scientific and Technical Center “Forage and Metabolism” according to generally accepted methods. The data obtained revealed a relationship between NDVI and the chemical composition of plants. The superiority of pasture plants with an NDVI index of 0.60 over grass stands with an NDVI index of 0.23 and 0.41 in terms of crude protein content by 1.3 percentage points and 2.35 percentage points. An analysis was also carried out on the amino acid composition of forage plants, where the result was better in grass with an NDVI of 0.60.
