Metabolism, a manifestation specific to life, represents the set of physical and chemical processes through which living matter achieves continuous renewal to function and organize the specific activity. The physical-chemical composition of goat milk is conditioned by breed, individuality, area, and age. This study analyzes the physical-chemical composition of milk from a population of Carpathian goat breed, in the first seven postpartum days (first, third, and seventh day) according to age (primiparous and multiparous) to observe the physical-chemical changes from colostrum to milk. The physical-chemical parameters analyzed were: fat (g/100 g); protein (g/100 g); casein (g/100 g); lactose (g/100 g); solid non-fat - SNF (g/100 g); total dry matter (g/100 g); pH; freezing point (FP); urea mg/dl; somatic cells count - SCC/ml x 1000; total bacteria count - TBC/ml x 1000. Results highlight the intense changes that occur at the physico-chemical level of goat's milk to cover the nutritional requirements of the newborn goat and indicate the health status of the mammary gland.
