Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract. The authors presented research materials on the study of ways to use pastures in semi-desert zone of West Kazakhstan. Purpose. Study of ways of grazing farm animals to increase productivity and rational use of pastures. The research object is the pasture lands of “Miras” farm in West Kazakhstan region. The research tasks were to select the most effective way of grazing, ensuring preservation and improvement of quantitative and qualitative indicators of semi-desert zone pastures. The research scientific novelty is in the fact that the determined grazing methods allow rational use of pasture resources and increase feed capacity of pasture lands. The studies were carried out in a semi-desert zone of West Kazakhstan on a relief and sandy area of pastures. Results. Unsystematic use of pastures reduces quantitative and qualitative indicators. In summer studies, the highest content of weeds and poisonous plants (9 %) was found on a pasture of unsystematic grazing. When using this method, the proportion of cereals in the phytocenosis was at least 9 %. In the composition of the phytocenosis used in an unsystematic way, an increase in the proportion of wormwood was noted up to 15 %. Here, in comparison with the 2nd seasonal pastures, the share of herbs (poorly eaten) is also high – 21 %. On the pastures used in a unsystematic way in the spring, the yield of herbage reached only 3.81 c/ha, which is less than the seasonal pastures by 2.50–4.28 c/ha or 65.6–112.3 %. In a semi-desert zone, to provide agricultural animals with high-grade and high-quality fodder, as well as to create a stock and reduce the shortage of fodder, it is advantageous to use seasonal pastures with the inclusion of a distant pasture area in the pasture rotation. The use of distant areas for seasonal use of pastures, increasing the duration of the pasture period by 120 days, allows the farm to additionally create the volume of actual feed storage at the level of 5 499.5 centners, reducing the level of feed deficit by 2 119.7 centners or 81.03 %.
