Seasonal fluctuations in individual milk parameters in free-range cows. Ukrainian Journal of Veterinary and Agricultural Sciences, 2025. Vol. 8. N 1. Р. 85–89. DOI: 10.32718/ujvas8-1.12UDC 636.2.09:637.1:006.015.5URL: https://ujvas.com.ua/index.php/journal/article/view/224/251https://dspace.pdau.edu.ua/handle/123456789/20144Understanding milk composition is essential for the Ukrainian dairy industry due to its impact on dairy products' nutritional value, processing characteristics, and functional properties. The drive to achieve high profitability in the dairy industry worldwide has led to different calving models and feeding systems depending on the region's most profitable and efficient form of milk production. This has led to significant regional differences in milk composition. The aim was to analyze individual indicators in raw milk from free-range cows. Their minimum and maximum limits were determined at Komyshuvatskyi Milk Complex LLC, which is key when determining the grade of milk. The content of fat, protein, and somatic cells of raw milk from the farm's industrial herd of cows was analyzed for the period from May 2023 to April 2024. The indicators we selected demonstrated seasonal trends. Significant relationships in the protein-fat system were identified.enmilkseasonalitysafetyindicatorsfatproteinsomatic cellsArticle
