摘要:

旨在研究不同饲粮叶酸水平对1~21日龄北京鸭生产性能、血浆生化指标和抗氧化能力的影响,以确定1~21日龄北京鸭叶酸需要量。试验采用单因子完全随机试验设计,选用640只体重相近的1日龄雄性北京鸭,随机分为8组,每组8个重复,每重复10只鸭。试验鸭分别饲喂叶酸水平为0.16、0.26、0.36、0.56、0.76、0.96和1.16 mg ·kg-1的试验饲粮,试验期为21 d。结果表明:1)0.76 mg ·kg-1叶酸组试验鸭的平均体重和平均日增重显著高于0.26、0.36和0.56 mg ·kg-1组(P < 0.05)。2)随着饲粮叶酸水平的提高,21日龄北京鸭的胸肌率(P=0.098 8)和腿肌率(P=0.075 3)具有先升高再降低的趋势。3)随着饲粮叶酸水平的提高,血浆谷草转氨酶活性显著降低,血浆葡萄糖水平显著提高(P < 0.05),当叶酸水平达到0.76 mg ·kg-1时,上述指标无显著变化。4)叶酸水平为0.16和0.36 mg ·kg-1组的血浆总抗氧化能力显著低于0.26和0.76 mg ·kg-1叶酸组(P < 0.05),0.16和0.26 mg ·kg-1叶酸组过氧化氢酶活性显著低于0.36、0.56、0.76、0.96和1.16 mg ·kg-1叶酸组(P < 0.05)。综上,饲粮中添加适宜水平的叶酸可提高北京鸭生产性能和抗氧化功能,在本试验条件下,推荐1~21日龄北京鸭饲粮叶酸水平为0.76 mg ·kg-1

Abstract:

This experiment was conducted to investigate the effects of dietary folic acid levels on production performance, plasma biochemical indicators, and antioxidant capacity of Pekin ducks from 1 to 21 days of age, and to determine the folic acid requirement of Pekin ducks. The experiment adopts a completely randomized single-factor experimental design. A total of 640 1-day-old male Pekin ducks with similar body weight were randomly divided into 8 groups, 8 replicates per group, and 10 ducks per replicate. Ducks were fed experimental diets with folate levels of 0.16, 0.26, 0.36, 0.56, 0.76, 0.96, and 1.16 mg ·kg-1, respectively. The experiment lasted for 21 days. The results showed as follows: 1) Average body weight and average daily weight gain in the 0.76 mg ·kg-1 folic acid group were significantly higher than that in the 0.26, 0.36, and 0.56 mg ·kg-1 folic acid groups (P < 0.05). 2) With dietary folic acid level increasing, breast muscle percentage (P=0.098 8) and leg muscle percentage (P=0.075 3) has the trend of first increasing and then decreasing. 3) With dietary folic acid level increasing, plasma aspartate aminotransferase activities were significantly decreased, and plasma glucose level was significantly increased (P < 0.05). When folic acid level was 0.76 mg ·kg-1, there was no significant change in the above indexes. 4) The total antioxidant capacity of 0.16 and 0.36 mg ·kg-1 folic acid groups was significantly lower than that of 0.26 and 0.76 mg ·kg-1 folic acid groups (P < 0.05). The catalase activity of 0.16 and 0.26 mg ·kg-1 folic acid groups was significantly lower than that of 0.36, 0.56, 0.76, 0.96, and 1.16 mg ·kg-1 folic acid groups (P < 0.05). In conclusion, adding an appropriate level of folic acid to the diet could improve the production performance and antioxidant capacity of Pekin ducks. The recommended folic acid level in the diet for Pekin duck from 1 to 21 days of age under the condition of the current study is 0.76 mg ·kg-1.
