本试验旨在研究日粮中添加无机铬（CrCl3·6H2O）对雏鸡生产性能和血清指标的影响。将100只1日龄Bovans型雏鸡随机分为4组。对照组不补充铬。另外3组分别在每kg日粮中添加0.2、0.3和0.4mg铬（Cr）。每个实验组由五个重复组成，每个重复五只鸡，并且补充持续35天。测定血清蛋白质、白蛋白、血糖、总胆固醇、高密度脂蛋白（HDL）、低密度脂蛋白（LDL）胆固醇、甘油三酯浓度及天门冬氨酸氨基转移酶（AST）、碱性磷酸酶（ALP）活性。所用剂量的铬对体重增加没有影响。补充铬降低血清总胆固醇、低密度脂蛋白胆固醇（p < 0.05）、甘油三酯（p < 0.05）和葡萄糖（p < 0.05）浓度，而升高血清高密度脂蛋白和胆固醇。血清总蛋白浓度、AST和ALP活性轻度升高，但不显著。治疗组。
This study was conducted to investigate the effect of increasing dietary levels of inorganic chromium (CrCl3·6H2O) on the performance and some serum parameters of chicks. One hundred 1-day-old Bovans-type chicks were randomly distributed to four groups. The control group received no supplemental chromium. 0·2, 0.3 and 0.4 mg chromium (Cr) per kg diet from chromium chloride were added to other three groups. Each experimental group consisted of five replicates of five birds each and the supplementation was continued for 35 days. Blood samples were collected for the determination of serum concentration of proteins, albumin, glucose, total cholesterol, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol, triglycerides and the activities of aspartate aminotransferase (AST) and alkaline phosphatase (ALP). Chromium by the doses used had no effect on weight gain. Supplementation with Cr decreased the serum total cholesterol, LDL cholesterol (p < 0.05), triglycerides (p < 0.05) and glucose (p < 0.05) concentrations whereas serum HDL and cholesterol were increased. Serum total protein concentration, AST and ALP activities slightly but not significantly increased in all Cr. treated groups.
