Background and Aim: Milk producers need to ensure that their cows are producing high-quality, nutritional milk, which is influenced by the breed, age, nutrition, and health status of lactating animals. The aim of this study was to determine the effect of animal breed, season, and milk production on the physicochemical characteristics of milk and predicting the effect of these changes on the composition and quality of milk products. Materials and Methods: In total, 80 milk samples (40 Simmental and 40 Holstein) were analyzed from LLP "Kirova" of Pavlodar region (Simmental breed) and JSC "Astana-Onim" of Akmola region (Holstein breed) in the Republic of Kazakhstan. The physicochemical parameters, including fatty acid (FA) content, were studied. Results: The Simmental cows had the lowest mass fraction of fat in the spring at 3.94% and the highest fat content in the winter at 4.09%, which was the overall highest fat content measured in both breeds (?<0.001). The lowest protein in the Simmentals was also measured in the spring. The Holstein cows had the highest fat content at 3.8% and the highest protein content at 3.3% in autumn. Conclusion: It was found that the season and breed significantly affected the physicochemical parameters and the FA contents in cow milk. The superiority of the Simmental cows over the Holstein cows throughout the year was statistically significant.

One of the most important factors that has a negative impact on the health of the population of the Republic of Kazakhstan is a violation of the diet, due to insufficient consumption of high-grade proteins, vitamins, macro- and microelements and their irrational ratio. In the Republic of Kazakhstan, cereals are produced in large volumes, but there is no production of beverages based on vegetable raw materials, although the production of plant-based milk is already widespread throughout the world. The use of local vegetable raw materials from different regions of the Republic of Kazakhstan in the production technology of cereal milk beverages is an actual and promising direction in the food industry. The results of a study of the quality of the following selection grain crops of the Republic of Kazakhstan are presented: rice "Syr Suluy", "Aykerim" and "Marzhan"; oats "Duman", "Bitik", "Arman"; buckwheat "Shortandin", "Batyr" and "Saulyk". The results of protein analysis in rice grains showed that the “Syr Suluy” variety has higher rates, which amounted to 7.96 %. In the studied samples of oat grains of the Duman variety, the mass fraction of carbohydrates is 2.8 %; 1.54 % higher than the varieties "Bitik" and "Arman". Protein analysis in buckwheat grains showed that the Shortandin variety (13.04 %) has higher rates. Studies have shown that the studied samples of grain crops in terms of safety comply with the requirements of the Technical Regulations of the Customs Union "On safety of grain". The data obtained will be used to develop new technologies for cereal beverages

One of the most important factors that has a significant impact on the health of the population of the Republic of Kazakhstan is a violation of the diet due to insufficient consumption of full–fledged proteins, vitamins, macro- and microelements and their irrational ratio. In Kazakhstan, grain crops are produced in large volumes, but there is no production of beverages based on vegetable raw materials, although the production of vegetable milk is already widespread throughout the world. The use of local vegetable raw materials from different regions of Kazakhstan in the production technology of grain milk drinks is an urgent and promising direction in the food industry. The article presents the results of a study of the quality of oats of breeding varieties "Duman", "Arman" and "Bityk". During the study, the physicochemical, technological properties and safety indicators of oat samples were evaluated. All the studied samples of oat grains in terms of safety meet the requirements of the Technical Regulations of the Customs Union "On grain safety". The scientific data obtained during the implementation of the project will become the basis for the creation of new grain "milk" drinks enriched with Omega-3 polyunsaturated fatty acids. The result of the implementation of this research will be the expansion of the range of beverages for healthy and safe nutrition of the population.

The research was to obtain information and assess the impact of region and seasonal changes on the physical-chemical indicators of milk, as well as to predict the impact of these changes on the composition and quality of products derived from such milk. To assess the differences in milk taken from different regions, as well as to identify the impact of the season on its quality, physical-chemical indicators, including the content of fatty acids in the milk of Holstein cows of the Republic of Kazakhstan were studied. To assess the health status of lactating animals, the content of somatic cells in milk was additionally assessed. The results of studies found that the season and the region significantly influenced the physical-chemical indicators of milk and the content of fatty acids in lipids.
