Influence of seasonal pasture rotation on animal productivity in Zhambyl region

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 %.
