Composition and Isolation of Lactoferrin from Colostrum and Milk of Various Goat Breeds

Dairy goats colostrum is one of lactoferrin source which has various benefits such as antimicrobial activity. The samples of colostrum and milk are samples of three breeds of goats. The highest concentration of lactoferrin in colostrum and milk is 88.70±12.11 mg/l for saanen goats crosses with PE goats (SAPE), with approximately molecular mass of lactoferrin is 83,513.3 Dalton and the last is 72.57±23.61 mg/l for peranakan etawah (PE), with approximately molecular mass of lactoferrin is 86,075.4 Dalton. These results have important information as a basic knowledge of the value of the concentration of lactoferrin in goat breeds.
