Abstract
In the new policy course "Strategy "Kazakhstan-2050": the task is to use natural pasture lands, including to revive the system of cattle breeding, taking into account new scientific, technological, and managerial achievements. The 35th and 97th steps of the National Plan "100 concrete steps" of the Head of State are also aimed at the development of domestic animal husbandry [1]. "In a market economy, due to the bankruptcy of large agricultural enterprises and their transition to new forms, feed production has become a loss-making industry. The refusal to cultivate annual and perennial crops led to a complete lack of forage, which led to a reduction in the number of cattle." The wide distribution of the wheat-grass on saline soils makes it possible to consider it a promising plant for the development of these lands. Therefore, it is usually sown where other plant species cannot grow. One of the main sources of pasture feed in the east of Kazakhstan is a long–term forage crop - broad-leaved wheat-grass. Due to its ecological plasticity, the wheat-grass occupies a leading position among hayfields and pastures, with a specific gravity of 60%. It also occupies a significant share in the composition of forage crops on natural pastures, which are the national heritage of the republic. The breadbasket is widely used to provide livestock with feed - an urgent problem of our time. The fundamental improvement of natural forage lands is aimed at creating highly productive hayfields and pastures, which makes it possible to increase forage collection.
