The specific properties of colostrum make it an indispensable source of nutrients and passive immunity for newborns. Feeding kids with colostrum within the first hours after parturition is extremely important for their health and survival. The composition of colostrum in different animal species is not the same. There is also a difference in terms of interbreeding. The present study aims to monitor the changes in the physicochemical parameters of colostrum from Anglo-Nubian (AN) goats that occurred within the first 24 hours after parturition. The study was conducted in the goat farm of the RIMSA, Troyan, Bulgaria, and a total of 40 colostrum samples were obtained from clinically healthy AN goats. For the studied period of 24 hours, a reliable decrease of the studied parameters was reported: protein (14.21-7.79%), total solids (24.02-20.84%), solid-not-fat (19.21-12.93%), density (1.045-10.354 g/ml3), acidity (32-21oT) and Ca (0.254-0.1494 mg/%). In contrast, for the indicators, such as fat (5.32-8.37%), lactose (2.63-3.43%), and pH (6.24-6.31), an increase in the values was observed.
