Традиционные кормовые культуры (кукуруза, горохо – овсяная смесь), возделываемые для производства силоса и сенажа в зональных условиях, не обеспечивают потребность сельскохозяйственных животных в сбалансированных низкозатратных кормах. С данной целью можно использовать малораспространенную кормовую культуру – горец забайкальский (Aconogonon divaricatum L.) в системе сенокосооборота.Горец забайкальский исследовали в умеренно – засушливых условиях Северного Казахстана. Учет урожая проводили по методике полевых опытов с кормовыми культурами, который был подвергнут математической обработке.В результате использования горца забайкальского в системе сенокосооборота, в период бутонизации – цветения, средняя урожайность зеленой массы составила 53.2 т / га, а в период цветения и цветения она была на уровне – 49.3 т / гa.Горец забайкальский используется для производства питательных кормов. Так в фазу бутонизации сырого протеина содержалось 12.6 %, обеспеченность белком 1 кормовой единицы – 138 г. Рентабельность производства сырья получена очень высокой – 590 % в соответствии с затратами 170 $ / га и прибылью – 1003 $ / га. Выход кормов: силоса, сенажа, витаминно–травяной муки по качеству соответствует ГОСТам.

Traditional forage crops (maize, pea and oats mixture) are not sufficient for livestock farming needs in balanced low – cost fodder. However, the demand for fodder can be met using such forage crop as Aconogonon divaricatum L. This plant was researched in semi – arid circumstances of North Kazakhstan steppes. Crop was recorded using field studies involving forage crops, which was later mathematically treated. As a result of using Aconogonon divaricatum L. in the system of cutting rotation, during the budding – blossoming phase, the forage mass rated 53·2 t ha–1, but during the blooming phase it was 49·3 t ha–1. Aconogonon divaricatum L. is used for the nutritional forage production. So in the budding phase crude protein content was 12·6 %, as protein supply of one fodder unit accounted 138 g–1. Production cost – effectiveness is very high – 590 % – in respect to input of 170 $ per ha–1 and profit of 1003 $ per ha–1. Fodder output (silage, haylage, vitamin – grass dried forage) quality meets the National Standard.
