| ANNOTATION
Most of the country's natural forage lands are located in the arid regions of Kazakhstan. This territory is the material basis and the starting base for the development of the leading pasture livestock industries - sheep breeding, camel breeding and horse-herding. The stable development of these industries in farms of various forms of ownership is largely determined by the state of forage lands. The creation of seeded forage lands by sowing perennial arid plants should provide animals with full- fledged protein feed. These plants contain a significant amount of protein, protein and have great nutritional value. The green mass and dry matter of the sown pastures are characterized by high biological value and contain much more nutrients than the natural pastures of the studied cultivation zones. The research was carried out on the territory of experimental sites of foothill and steppe zones located on the territory of Ordabasinsky and Aryssky districts. The total area of the experimental plots is 125 hectares. The basis of the soil cover of the foothill zone is ordinary loamy serozem, light sandy loam in the steppe zone. It should be noted that the natural pastures of the studied region are unproductive. Due to seasonality, they cannot provide animals with highly nutritious protein feed throughout the entire pasture period. In this regard, the chemical composition of seed multicomponent and natural agrophytocenoses has been studied. As a result of the conducted studies, it was found that the chogona plant should be attributed to high-quality feeds in terms of chemical composition in the steppe zone, the protein content of this plant species is 19,8%, ash 7,3%, fiber 27,4%, and a greater amount of fat 6,8 compared to other tested plants. Ключевые слова: аридные кормовые культуры, химический состав, питательность, предгорная и степная зона. жүктеу/скачать 7.12 Mb. Достарыңызбен бөлісу:
