Plasma was obtained from normal laying hens, 30 weeks of age, and from laying hens, 60 weeks of age, with fatty liver syndrome (FLS). The 60-week-old hens were divided into two groups based on whether they were laying or nonlaying. Plasma phosphorus and calcium was significantly higher for hens with FLS. The younger hens had significantly lower 25-dihydroxyvitamin D3 (25-OH-D3) plasma levels than the older hens. The older hens that were laying had significantly lower 25-OH-D3 plasma levels than the nonlaying hens. Old nonlaying hens with FLS had lower 1, 25-OH-D3 than young hens or old laying hens with FLS; however, the levels were not different for the two groups of laying hens.
血浆取自30周龄的正常产蛋母鸡以及患有脂肪肝综合征（FLS）的60周龄产蛋母鸡。60周龄的母鸡根据是否产蛋分为两组。患有FLS的母鸡血浆磷和钙水平显著更高。年轻母鸡的血浆25-二羟基维生素D3（25-OH-D3）水平显著低于年长母鸡。产蛋的年长母鸡的血浆25-OH-D3水平显著低于不产蛋的母鸡。患有FLS的不产蛋老龄母鸡的1,25-OH-D3水平低于患有FLS的年轻母鸡或产蛋老龄母鸡；然而，两组产蛋母鸡的该水平没有差异。
