The article presents the results of field research on pastures with the participation of protective forest plantations in the arid steppe zone of the West Kazakhstan region. The purpose of the study is to assess the impact of used pastures with the participation of protective forest plantations on productivity, vegetation cover, biological diversity and animal feed value. The studies were conducted in 2024-2025, and traditional natural pastures were taken as a control option. The results of the study showed that the projective vegetation coverage in pastures where "green" technology was used was high during all seasons. This increased the resistance of pastures to degradation and prevented soil erosion. In particular, in the spring period, the projected coverage was 87.5%, which is about 20% higher than in the control period, and in the summer this figure reached 96%. During the study, the number of species of pasture plants also increased, 24.0 species were registered in spring using "green" technology, and in the control version this indicator was 15.5. Increasing the number of species can increase ecosystem resilience and ensure long-term pasture productivity. The height of plants and the yield of green mass have also reached high values in the conditions of "green" technology. For example, if in the spring a height of 25.6 cm and a yield of 8.28 kg/ha were recorded in the control, then in the "green" technology they were 35.13 cm and 13.14 kg/ha. The results show that this technology has had a positive impact on feed and energy-protein values. When using the "green" technology, the dry matter content increased by 37.57% and decreased slightly compared to the control, but the crude protein content increased to 10.03% and became the basis for increasing livestock productivity. There was also an increase in the amount of crude fat, calcium, potassium, and phosphorus, as well as an increase in carotene levels. The yield of dry matter, feed units, digestible protein and metabolic energy were significantly higher compared to the control variant. The results of the study provide a complete opportunity to present "green" technology as a scientifically sound, environmentally and economically efficient technology for the efficient use of pastures, increasing their productivity and biodiversity, improving feed quality and energy efficiency. Proper use and maintenance of pastures is the main condition for increasing livestock productivity.
