试验旨在研究饲粮铬水平对育成期笼养蛋鸭生长性能、血液生化指标的影响。试验采用单因素完全随机分组设计，选择健康28日龄金定蛋鸭180只，随机分成5组，每组6个重复，每个重复6只鸭。对照组(Ⅰ组)饲喂玉米－豆粕型基础饲粮，试验组(Ⅱ~Ⅴ组)分别在基础饲粮中添加0.15、0.30、0.45、0.60 mg/kg铬（吡啶羧酸铬），试验期6周。结果表明：①在饲粮中添加铬（吡啶羧酸铬）对笼养蛋鸭的日增重影响差异显著（P<0.05），但对采食量和料重比影响差异不显著（P>0.05）；②一定量的铬（吡啶羧酸铬）对笼养蛋鸭的血糖、总胆固醇、甘油三酯产生显著影响(P<0.05)，并促进了血清总蛋白、白蛋白的提高，同时显著降低了血清尿素氮的含量(P<0.05)。最终通过二次曲线回归方程对添加量和测定指标结果进行回归分析，得出结论：铬(吡啶羧酸铬)在育成期笼养蛋鸭饲粮中最适宜的添加量为0.2970~0.4225 mg/kg。
試驗旨在研究飼糧鉻水平對育成期籠養蛋鴨生長性能、血液生化指標的影響。試驗採用單因素完全隨機分組設計，選擇健康28日齡金定蛋鴨180隻，隨機分成5組，每組6箇重複，每箇重複6隻鴨。對照組(Ⅰ組)飼餵玉米－豆粕型基礎飼糧，試驗組(Ⅱ~Ⅴ組)分彆在基礎飼糧中添加0.15、0.30、0.45、0.60 mg/kg鉻（吡啶羧痠鉻），試驗期6週。結果錶明：①在飼糧中添加鉻（吡啶羧痠鉻）對籠養蛋鴨的日增重影響差異顯著（P<0.05），但對採食量和料重比影響差異不顯著（P>0.05）；②一定量的鉻（吡啶羧痠鉻）對籠養蛋鴨的血糖、總膽固醇、甘油三酯產生顯著影響(P<0.05)，併促進瞭血清總蛋白、白蛋白的提高，同時顯著降低瞭血清尿素氮的含量(P<0.05)。最終通過二次麯線迴歸方程對添加量和測定指標結果進行迴歸分析，得齣結論：鉻(吡啶羧痠鉻)在育成期籠養蛋鴨飼糧中最適宜的添加量為0.2970~0.4225 mg/kg。

The experiment was conducted to study the effects of different levels of chromium on the growth performance and blood biochemical indices of caged growing laying ducks. Using a single factor completely randomized design, a total of 180 Jin-ding laying ducks, 28-day-old, were randomly allocated to 5 groups with 6 replicates of 6 each. The laying ducks were fed corn-soybean meal basal diet supplemented with 0,0.15,0.30,0.45 mg/kg and 0.60 mg/kg chro?mium as chromium picolinate, respectively. The experimental period lasted for 6 weeks. The re?sults showed as follows:①Average daily gain was significantly increased (P<0.05) in caged growing laying ducks fed diet supplemented with chromium as chromium picolinate, but average daily feed intake and feed to gain was insignificantly different from each other (P>0.05). ②The contents of serum GLU, TC and TG were reduced significantly (P<0.05) and the contents of se?rum TP and ALB were increased significantly with supplemental chromium as chromium pico?linate(P<0.05)in caged growing laying ducks. Meanwhile, the contents of serum BUN were also reduced significantly(P<0.05). The results indicated that the optimum adding level of chromi?um as chromium picolinate was 0.297 0~0.422 5 mg/kg by fitting a quadratic regression curve.
