为研究不同水平的吡啶羧酸铬对生长期（5～10周龄）笼养蛋鸭免疫器官指数和抗氧化功能的影响，试验采用单因素完全随机分组设计，选择28日龄健康金定蛋鸭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-豆粕型基础日粮，试验组（Ⅱ～Ⅴ组）分别在基础日粮中添加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）Ⅱ、Ⅲ、Ⅳ组的胸腺指数分别比Ⅰ组提高27.65%、29.33%、24.30%（P ＜0.05），但对脾脏指数和法氏囊指数未产生显著影响（P＞0.05）。（2）添加适量的吡啶羧酸铬可提高肝脏的总抗氧化能力，Ⅲ组最高，分别较Ⅰ、Ⅴ组提高12.04%、10.44%（P＜0.05），Ⅳ组血清中总超氧化物歧化酶的活性比Ⅰ组提高4.70%（P＜0.05），Ⅲ组肝脏中总超氧化物歧化酶的活性较Ⅰ、Ⅴ组分别提高4.93%、3.98%（P＜0.05），Ⅱ、Ⅲ、Ⅳ组血清中丙二醛的含量分别比Ⅰ组降低9.35%、10.79%、10.07%（P＜0.05）。但添加吡啶羧酸铬对谷胱甘肽过氧化物酶的活性影响不显著（P＞0.05）。通过二次回归曲线分析表明铬（以吡啶羧酸铬形式添加）在生长期笼养蛋鸭日粮中最适宜的添加量为0.3189～0.3492 mg/kg。
為研究不同水平的吡啶羧痠鉻對生長期（5～10週齡）籠養蛋鴨免疫器官指數和抗氧化功能的影響，試驗採用單因素完全隨機分組設計，選擇28日齡健康金定蛋鴨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-豆粕型基礎日糧，試驗組（Ⅱ～Ⅴ組）分彆在基礎日糧中添加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）Ⅱ、Ⅲ、Ⅳ組的胸腺指數分彆比Ⅰ組提高27.65%、29.33%、24.30%（P ＜0.05），但對脾髒指數和法氏囊指數未產生顯著影響（P＞0.05）。（2）添加適量的吡啶羧痠鉻可提高肝髒的總抗氧化能力，Ⅲ組最高，分彆較Ⅰ、Ⅴ組提高12.04%、10.44%（P＜0.05），Ⅳ組血清中總超氧化物歧化酶的活性比Ⅰ組提高4.70%（P＜0.05），Ⅲ組肝髒中總超氧化物歧化酶的活性較Ⅰ、Ⅴ組分彆提高4.93%、3.98%（P＜0.05），Ⅱ、Ⅲ、Ⅳ組血清中丙二醛的含量分彆比Ⅰ組降低9.35%、10.79%、10.07%（P＜0.05）。但添加吡啶羧痠鉻對穀胱甘肽過氧化物酶的活性影響不顯著（P＞0.05）。通過二次迴歸麯線分析錶明鉻（以吡啶羧痠鉻形式添加）在生長期籠養蛋鴨日糧中最適宜的添加量為0.3189～0.3492 mg/kg。

The experiment was conducted to study effects of different levels of chromium as chromium picolinate on immune organ index and antioxidant function of caged growing laying ducks aged from 5 to 10 weeks.Using a single factor completely randomized design,a total of 180 28-day-old Jin-ding laying ducks were randomly allocated to 5 groups with 6 replicates in each group.The control group (groupⅠ)was fed corn-soybean meal basal diet,and the experimental groups (groupsⅡ~Ⅴ)were fed corn-soybean meal basal diet supplemented with 0.15,0.30,0.45 mg/kg and 0.60 mg/kg chromi-um as chromium picolinate respectively.The experimental period lasted for 6 weeks.The results showed as follows:(1)Thy-mus index of groupⅡ,Ⅲ,Ⅳincreased by 27.65%,29.33%and 24.30%compared with group Ⅰrespectively(P<0.05), but there was no significant effect on spleen index and bursa index (P > 0.05).(2)The total anti-oxidant capacity (T-AOC) in liver of groupⅢwas the highest and increased by 12.04%and 10.44%compared with group Ⅰ,Ⅴrespectively (P<0.05),and the activity of total super oxide dismutase (T-SOD) in serum of group Ⅳ increased by 4.70% compared with groupⅠ (P<0.05) and the activity of total superoxide dismutase (T-SOD)in liver of group Ⅲincreased by 4.93%and 3.98% compared with groupⅠ,Ⅴ respectively(P < 0.05).The contents of serum malondialdehyd(MDA)of group Ⅱ,Ⅲ, Ⅳreduced by 9.35%,10.79% and 10.07% compared with group Ⅰ respectively (P < 0.05).But the activity of glu-tathion peroxidase(GSH-Px)was insignificantly different from each other(P>0.05).The results indicated that the optimum adding level of chromium as chromium picolinate in the diet of caged growing laying ducks was 0.3189 ~0.3492 mg/kg by fitting a quadratic regression curve.
