Serum levels of fructosamine were assayed in 57 samples from 23 Norwegian Red Cattle dairy cows in early lactation. The animals were assigned to a 2 factorial feeding experiment. The groups differed in energy and protein supply. All samples were collected before morning feeding. The relationship between fructosamine levels and the plasma concentrations of glucose, acetoacetate, free fatty acids, total cholesterol, lipoproteins, triglycerides, total proteins, progesterone and to weight and energy balance was studied. The overall mean fructosamine level was 1.41 ± 0.20 mmol/1 ranging from 0.92–1.92 mmol/1. Significant relationships were recorded between fructosamine and the concentrations of glucose, acetoacetate, free fatty acids, triglyceride, total cholesterol and energy and weight balance. Free fatty acids and cholesterol showed the best correlation with fructosamine (r =–0.67 and 0.70, respectively, p < 0.001). The levels of fructosamine increased significantly between 2 and 4 weeks and between 4 and 8 weeks after calving. Animals with a weight gain during 3 weeks prior to fructosamine measurement had higher fructosamine levels than those showing a weight loss (<–7 kg/week) (p < 0.05). The results indicate that serum fructosamine levels in cows may be of interest as an indicator of metabolic status in the early stages of lactation.
对23头处于泌乳早期的挪威红牛奶牛的57份血清样本进行了果糖胺水平检测。这些动物被分配到一项二因素饲养实验中。各组在能量和蛋白质供应方面存在差异。所有样本均在晨饲前采集。研究了果糖胺水平与血浆中葡萄糖、乙酰乙酸、游离脂肪酸、总胆固醇、脂蛋白、甘油三酯、总蛋白、孕酮以及体重和能量平衡之间的关系。果糖胺的总体平均水平为1.41±0.20 mmol/1，范围在0.92 - 1.92 mmol/1之间。记录到果糖胺与葡萄糖、乙酰乙酸、游离脂肪酸、甘油三酯、总胆固醇的浓度以及能量和体重平衡之间存在显著关系。游离脂肪酸和胆固醇与果糖胺的相关性最佳（分别为r = -0.67和0.70，p < 0.001）。产犊后2至4周以及4至8周期间，果糖胺水平显著升高。在测量果糖胺前3周体重增加的动物，其果糖胺水平高于体重减轻（<-7 kg/周）的动物（p < 0.05）。结果表明，奶牛血清果糖胺水平作为泌乳早期代谢状态的指标可能具有研究价值。
