摘　　要：本试验旨在探讨饲料营养对柴蛋鸡产蛋率、蛋品质、血液生化指标和蛋中某些矿物质元素含量的影响。从北京市昌平区(韩台、黑山寨、泰陵鸡场)及顺义区(都市农庄(简称都市)、梨园鸡场)5个柴蛋鸡散养场各选择100只日龄和体重基本一致的产蛋鸡,随机分为对照组和试验组,每组设5个重复,每个重复10只鸡。对照组以玉米为主要日粮,试验组在以玉米为主要日粮中添加适量的微量元素、维生素等营养元素。试验期52d。结果表明,不同散养鸡场中试验组柴蛋鸡的产蛋率均显著高于对照组(P<0.05);韩台、都市、泰陵和梨园鸡场试验组鸡蛋的蛋重显著高于对照组(P<0.05),梨园鸡场对照组鸡蛋的蛋白高度显著高于试验组(P<0.05),都市和梨园鸡场试验组鸡蛋的蛋黄颜色显著高于对照组(P<0.05),而蛋形指数、蛋壳厚度、平均蛋壳强度各组间均无显著差异(P>0.05);黑山寨鸡场试验组柴蛋鸡血浆中总蛋白、甘油三酯含量显著高于对照组(P<0.05);韩台和都市鸡场试验组鸡蛋中钙含量显著高于对照组(P<0.05),都市鸡场试验组鸡蛋中铜、镁及韩台鸡场试验组鸡蛋中锰、铁含量均显著高于对照组(P<0.05),黑山寨鸡场试验组鸡蛋中镁含量显著高于对照组(P<0.05)。综上所述,日粮中添加适量的营养元素可明显提高柴蛋鸡的产蛋率及鸡蛋中钙、锌和镁等矿物质元素的含量,提高柴蛋鸡血液总蛋白、胆固醇和甘油三酯含量,显著改善柴蛋鸡的营养状况。This study was conducted to investigate the effect of nutrients on laying rate, egg quality,blood biochemical indices and certain mineral elements of laying hens under free range system. 100 laying hens with similar age and weight were respectively selected from each farm, Hantai, Heishanzhai,Tailing in Changping and Doushi, Liyuan in Shunyi poultry farm, and randomly al- lotted to 2 groups with 5 replicates per group and 10 hens per replicate. The control group was fed with corn as the main diet and test group was fed with corn as the main diet supplemented with appropriate of trace elements,vitamins and other nutrients. The trial lasted for 52 days. The re- suits showed that the laying rate of test group was significantly higher than that of control group in different farm （P^0.05）. The egg weight of test group was significantly higher than that of control group in Hantai, Doushi, Tailing and Liyuan （P〈0. 05）. The protein height of control group was significantly higher than that of test group in Liyuan （P〈0.05）. The yolk color of test group was significantly higher than that of control group in Doushi and Liyuan （P〈0.05）. There wereno significant differences in the egg index, shell thickness and average shell strength among all groups （P〉0.05）. The plasma contents of TP and TG of test group was significantly higher than that of control group in Heishanzhai （P〈0.05）. The content of Ca in egg of test group was significantly higher than that of control group in Hantai and Doushi （P〈0.05） ,the contents of Cu and Mg of egg in Doushi and the contents of Mn and Fe of egg in Hantai of test group were significantly higher than that of control group （P〈0.05） ,the content of Mg in egg of test group was significantly higher than that of control group in Heishanzhai （P〈0.05）. In conclusion,adding appropriate level of nutrients could im- prove the laying rate and the contents of Ca, Zn, Mg and other minerals in egg,increase the plasma contents of TP,TG and CHO,and signific
