Milk is an important food obtained from mammals, containing almost all of the nutrients needed for metabolism. The vitamin composition of milk, the first food of mammals, is valuable data for the food industry and public health. This study aimed to determine the levels of folic acid (vitamin B9), cobalamin (vitamin B12), and biotin (vitamin B7) in different milk samples (cow, sheep, goat) using the ELISA method. For this purpose, milk samples from Holstein Cows (n:50), Awassi Sheep (n:50), and Kilis Goats (n:50) available for retail in the Şanlıurfa province of Turkey were collected and analyzed. In this study, the average folic acid content of sheep, goat, and cow milk was found to be 3.45 µg/100 mL, 7.23 µg/100 ml, and 6.64 µg/100 mL, respectively. The average cobalamin content of sheep, goat, and cow milk was 0.70 µg/100 ml, 7.43 µg/100 ml, and 0.58 µg/100 mL, respectively, while the average biotin content of sheep, goat, and cow milk was 2.21 µg/100 mL, 2.21 µg/100 mL, and 2.09 µg/100 mL, respectively. It was noted that the average biotin levels in sheep, goat, and cow milk did not differ significantly. However, significant differences were observed in the quantities of folic acid and cobalamin (P
