Short summary
This paper explains the influence of a sheep's lactation stage on the physical and chemical properties, hygienic quality and fatty acids in milk produced by Lacaune sheep kept in intensive breeding. A significant increase in the content of fat, protein, total dry matter and casein and a significant decrease in the content of lactose in the late stage of lactation were observed. Analysis of fatty acids in milk proved a decrease in C18:2n6, C18:3n6, n6 and n6/n3 ratios during lactation.
