Abstract
An experiment was conducted to investigate the effects of feeding Bupleurum falcatum L.(BFL) on performance, blood component and hormonal secretion in broiler breeder hens. A total of 800 broiler breeder hens were allotted to four treatments(BFL ; 0, 0.5, 1.0, 2.0%) with four replications for eight weeks. Weight gain was not significantly different between the groups in growing period($20{\sim}24$ weeks), but egg production and egg mass of broiler breeder hens fed BFL were significantly(p<0.05) higher than those of the control groups in laying period($24{\sim}28$ weeks). Dietary BFL did not affect serum triglyceride concentration, whereas serum cholesterol concentration was significantly increased(p<0.05) in 2.0% BFL-fed groups. No statistical differences were found in serum glucose, Ca, P, Mg, total protein, albumin, GGT, AST, ALT and BUN concentrations. However, albumin/globulin ratio was statistically higher in BFL-fed groups compared to the control groups(p<0.05). Serum estrogen concentrations were significantly increased by feeding a diet containing 0.5% BFL, but progesterone were not influenced. Serum IGF-I of BFL groups was greater than that of control groups at 28 weeks(p<0.05). In conclusion, the results suggest that the dietary addition of BFL into broiler breeder diets improved egg production, serum estrogen and IGF-I concentration, and decreased serum cholesterol concentration and albumin/globulin ratio.
