Abstract

This study was carried out to determine the effect of diets containing humic acid on composition and quality traits of milk (selected) in 18 Sannen goats. The animals (2 years old, 52 kg live body weight) were in 2nd lactation and 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 3×3 Latin square design experiment. Each period consisted of a 21d -adaptation phase and a 7 d- sample collection phase. Milk samples were collected at the end of the sample collection periods. Total DM intake values were found to be 1.73, 1.74 and 1.79 kg d-1 for T1, T2 and T3, respectively. 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. The administration of humic acid did not increase hygienic quality of milk. Somatic Cell Count of milk were determined as 257, 212 and 189 SCC (x 103) for T1, T2 and T3, respectively (P>0.05). Total Bacteria in milk were also determined as 239.7, 154.9 and 159.7 TB (x103). In conclusion, administration of humic acid had a minor effect on somatic cell count and total bacteria.
