Topicality

The project aims to address a key issue in livestock farming in Northern Kazakhstan—the reduction in the nutritional value of feed during long-term storage, which limits the productivity of agricultural animals. The natural and climatic conditions of Kazakhstan impose significant constraints on the use of pastures for livestock, making year-round grazing impossible. According to the Regulations for the Rational Use of Pastures in the Republic of Kazakhstan, livestock housing is utilized, and corresponding reserves of roughage are created under unfavorable weather conditions. On average, in Northern Kazakhstan, agricultural animals are kept in stall-based housing for over six months per year, with their diet based on roughage and succulent feeds such as hay, silage, and haylage. However, at all stages of harvesting and storage, feed loses nutrients, which negatively impacts animal productivity, particularly in dairy breeds.

Objective

The project's objective is to develop and implement effective methods for preserving the nutritional value of pelleted feeds and enhancing their digestibility through the application of antioxidant and antimicrobial agents that ensure long-term storage.

Project outcomes

Evaluation of nutrient preservation (fiber, protein, fats) at various stages after pelleting—based on physicochemical analysis conducted immediately after the process and throughout the storage period.

Establishment of quantitative parameters for changes in the content of key nutrients depending on the pelleting process—identification of optimal conditions to minimize losses of fiber, proteins, and fats during feed pelleting.

Investigation of the impact of pelleting on the preservation of feed nutritional value during long-term storage—determination of key factors influencing nutrient stability throughout the storage period.

As a result of the project implementation, dairy farms and livestock enterprises in the region will be offered effective methods for preserving the nutritional value of pelleted feeds, ensuring long-term storage without quality loss, which will significantly improve the feed base.
