The aim of the present study was to identify the metabolic changes that have occurred in Hanwoo Native Cow. Analysis of serum metabolites was carried out to investigate relationship of pregnancy rate and feeding systems. Totally, 281 cows were used for grazing and barn feeding. Grazing was carried out for 5 months in the pasture. In barn feeding, concentrate 3.0 Kg(TDN 68%, CP 14%) and rice straw 6 kg(TDN 50%, CP 6.5%) were fed. Artificial insemination(AI) carried out by timed AI procedure. The level of glucose(mg/dl), cholesterol(mg/mL), BUN(mg/dl), AST(U/l), ALT(U/l), and NEFA(uEq/l) were analyzed. In Table 1, barn feeding with 120% group was showed high Cholesterol and BUN levels compared those with 80% feeding group(p0.05). In Table 2, 60 pregnant cows in grazing herd showed low Cholesterol, AST and NEFA levels compared to 43 non-pregnant cows(149.8±4.9, 99.1±2.6, 326.7±15.7 vs. 165.9±4.6, 108.9±3.2, 419.2±32.8, respectively, p less than 0.05). In Table 3, 126 grazing feeding cows showed high Glucose, Cholesterol, AST, ALT, and NEFA levels compared to 22 barn feeding cows(84.8±1.3, 142.5±2.5, 97.7±2.3, 34.3±0.5, 317.8±13.6 vs. 56.0±1.3, 128.9±4.6, 80.9±2.0, 27.1±0.9, 160.2±18.9, respectively, p less than 0.05). Further study needed to obtain more accurate level of metabolites in serum for pregnant and non-pregnant cows.
