For a long time a man seeks for the most acceptable plants for domestic agricultural animals and men's feeding which would be fruitful and rich with valuable nutritive matters. First of all, it refers to the full proteins, vitamins, microelements,vegetable oils and other biologically active compounds. In this respect a new feed crop - a hybrid of the first generation received from the herb patience (English spinach) and Tien Shan sorrel - Rumex K-1, created in the Central Botanical Gardens named after Grishko at the Ukrainian National Academy of Science is of great interest. The author of the crop is Uteush Y.A. In 1999 our company acquired the right to cultivate, apply and sell Rumex K-1 (seeds and products of Rumex K-1) within the territory of republic. Our company is the exclusive official supplier of seeds Rumex K-1 in Kazakhstan. Other companies selling and advertising products based on Rumex K-1 infringe the author's rights which is penal action. The point is not only in law violation. We are selling elite seeds of almost 100 % germinating capacity. Besides, we possess all documentation regarding crop cultivation, development of Rumex K-1 application in the different fields. Our scientists have performed enormous theoretical and practical work on increase in the crop's quality so presently Rumex exceeds much more initial characteristics. At the stage of successful realisation project on development and improvement of existing technologies for cultivation of Rumex K-1, development of feed based on Rumex for various kinds of agricultural animals, birds and fish, medicinal and prevention diets, food intake, specialised food products and biologically active additives. This draft shall be developed by scientists of Research Institute for Human and Animal Physiology, Research Institute for Botany and Phytointroduction, Research Institute for Food and Research Institute for Food Industry.
