Keywords:pastures, degradation, natural herbage, natural areas, vertical zoning, soil moisture, yields.
This article presents the results of comprehensive research on the rational use of natural pastures with seasonal use in a specific area. The study was conducted in 2015-2017 on the land of the farm “Batyr” of the Kordai district of the Zhambyl region. 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 were 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 studying the productivity of sheep,it was revealed that a higher increase in live weight was obtained in the experimental group of animals where seasonal grazing was used. The seasonal pasture 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. The implementation of the research 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 sheep production through rational grazing up to 12%.
