A study by Polish scientists has highlighted the importance of cow's milk in the food industry, given its productivity and versatility. The researchers reviewed articles on milk quality from various housing systems. In 2019, cow's milk production exceeded goat and sheep milk by 36 and 68 times, respectively, with Europe being the leading producer. The quality of raw milk is crucial for product taste and texture, especially in cheese production. The quality is influenced by genetic and environmental factors, with the diet being a key factor. The study also noted the shift towards organic milk production, which adheres to strict standards including the ban on certain feed and the requirement for constant access to open areas.
