%X This study was carried out to determine the effect of diets containing humic acid at different levels on some blood and milk components in Saanen goats. Saanen goats (2 years old, 52 kg live body weight) were fed three diets, containing 0 g kg-1 humic acid (T1), 1 g kg-1 humic acid (T2) and 3 g kg-1 humic acid (T3) in a 3x3 Latin square design experiment. Compared to the control group, T1 - treated group produced more milk/day (P<0.05; 2.45 vs. 2.11 kg d-1) and this yield was similar to that of T2 - treated group. The fat (3.55, 3.67 and 3.58 %), non-fat solids (SNF) (8.41, 8.30 and 8.58 %), protein (3.73, 3.60 and 3.92 %) and lactose percentages of milk (3.82, 3.83 and 3.77) were similar for T1, T2 and T3 groups. Humic acid administration significantly reduced total cholesterol in blood (P<0.05; 124.1, 100.8 and 102.2 mg dL-1) for T1, T2 and T3, respectively. The LDL cholesterol levels in blood serum of T1, T2 and T3 groups were 23.49, 15.14 and 16.19 mg dL-1, respectively (P<0.05). Further investigation is required to elucidate the effects of humic acid on goat performance.
