Daidzein과 Genistein의 급여가 어린 병아리의 골격발달에 미치는 영향
초록
DE와 GE의 급여가 어린 병아리의 골격발달에 미치는 영향을 알아보기 위해 1일령된 Hy-Line Brown 수평아리 4처리
This study was designed to investigate the effects of dietary isoflavones(IF) on bone ash content in young chicks. Daidzein(DE) and genistein(GE), aglycone forms of IF, were added to purified-type basal diet containing calcium at 50% of NRC requirement. The two IF at two different levels(1.0 and 2.0 mM) were added to the diets prepared to be very low in IF using soy protein concentrate(SPC) as the only source of protein. The diets Including control with no IF-added were fed for three weeks. One hundred, Hy-Line Brown, day-old male chicks were divided into five dietary groups with four replicates and five chicks per replication. General performances of the chicks were not affected by the dietary treatments. Serum alkaline phosphatase(ALP) activities, an indicator for bone formation, of the birds fed DE diet were lowered compared to those fed GE and control diets. However, the levels of IF did not show any differences in the responses. Bone ash o/o of birds fed the IF diets were significantly increased compared to that of control group (p〈0.05), and, however, not affected by levels of IF in diets. Bone breaking strength measured with an Instron appeared to be equivalent among the birds of all treatments. The observations that equivalences in bone ash o/o and bone breaking strength even with lowered activity of ALP by DE ingestion compared to GE suggest a necessity of further investigation.
