Complex research is carried out on the rational use of natural pastures with seasonal use in a specific area. The research was conducted in 2015-2017 on the lands of “Batyr” farm in Korday district of Zhambyl region. The pasture lands of the farm consists of 5 independent sites and are located in 3 geographical areas: foothill-steppe (950 hа), foothill-dry steppe (1370 hа) and foothill-semi-desert (1880 hа). The total area of distant pastures is 4.200 hectares. As a result of conducting of geobotanical researches, the farm territory of peasant farm "Batyr" in Korday district of Zhambyl region was divided into seasons (spring-summer-autumn) of their use, the yield of natural herbage and live weight gain of animals was determined. Results of accounting of productivity of natural herbages on zones, seasons of year are given in article and the gain of livemass of animals for the pasturable period is defined. When determining efficiency of sheep it is revealed that higher additional weight of a liveweight is received in experimental group of animal. The seasonal pasture on average in three years of researches at the end of the pasturable period provided an increase of a live weight of rams on 3.370 kg/head at ewes on 8.020 kg/head and lambs of birth year on 8.640 kg/head is more in comparison with control groups of animals. It should be noted that for the pasturable period the increase of alive mass of animals in experimental group in 2017 is higher than a research in comparison with previous years. In 2017 at a pasture of animals on seasonal sites it was applied intra seasonal pasture turnover at which unproductive driving of animals in search of a forage on the grazing square is practically reduced three times, besides degradation of the pasturable territory is completely excluded. It was found that the use of seasonal use of pastures provides more weight gain studied animals compared to animals that graze in one place with an unsystematic manner of grazing. The implementation of the results created the conditions for the restoration of degraded pastures with an increase in the growth and development of vegetation cover up to 15-18 % and an increase in livestock production through rational grazing up to 12 %.

In this article, comprehensive studies have been conducted on the effective use of natural pastures in conditions of vertical zonality in the project territory of Batyr Korday district (Zhambyl region). The data presented shows how important it is to comply with the norms and loads of pastures for further preservation of pasture yields and prevention of degradation. Consequently, there is a need to develop effective and scientifically-based systems of pasture turnover and the introduction of measures to restore pasture lands in the Zhambyl region, taking into account the peculiarities of the climate and geo-botanical indicators. Pasture lands make up about seventy percent of the entire territory of the Republic of Kazakhstan. The potential productivity of these lands reaches twenty-five and more million tons of fodder units. Pasture is the main renewable forage plant resource. It should be emphasized that haphazard use has led to the fact that land degradation processes occur on 27.5 million hectares of pastures, feed capacity decreases, biological diversity decreases, erosion processes manifest themselves, etc. All this requires the development of science-based approaches to the exploitation of pasture resources, compliance with the basic elements of rational grazing. The current situation may have a twofold path of development. The first way is the absence of strategic initiatives for the effective use of pastures for small producers will lead to a final reduction in the feed capacity of the pastures used. And the second way is small and large-scale use of the huge forage potential of the restored pastures.

In this article, comprehensive studies have been conducted on the rational use of natural pastures, taking into account the seasons and typology, which allows increasing the grazing capacity of forage lands, as well as obtaining high-grade valuable and cheap livestock products. Rational maintenance of livestock on pastures not only reduces fuel costs by 6-7 times, equipment, labor and total feed costs by 2-3 times compared to the content of grazed animals, but also improves metabolic processes and reproductive functions of animals. This determines the great advantage of pasture feeding in the production of important livestock products. In the conditions of vertical zonality of the Zhambyl region, a significant reserve for increasing the production of mutton is their grazing on pasture with the use of pasture turnover; which allows the most efficient use of natural forage lands, increase the live weight and fatness of animals.
