摘要
选取3 600只248日龄海兰褐蛋鸡,饲以常规叶酸含量的玉米-豆粕型基础日粮。随机分为2组,每组1 800只,每组10个重复,每个重复180只。第一组为对照组,饲喂玉米-豆粕型基础日粮(叶酸含量为0.6 mg/kg)。第二组为试验组,在基础日粮的基础上添加3 g/kg的叶酸添加剂。试验期25 d。结果表明:饲粮中添加叶酸能够提高鸡蛋中的叶酸含量,且对蛋鸡的产蛋性能无不良影响。鸡蛋中叶酸含量的检测结果表明,添加叶酸21 d后,鸡蛋中的叶酸含量达到饱和。
3 600 Hyline hens of 248 day-old fed with corn-soybean basal diet were randomly divided intotwo groups. Each group contained 10 repeats which were composed of 180 hens. One group was control, theother group was experimental group supplemented with the basal diet and 3 g/kg folic acid for 25 days. Theresults showed that the folate content of eggs can be increased by increasing the level of crystalline folic ac-id in the laying hen diet and there were no differences in laying performance. According to the test results,maximal egg folate level was achieved after feeding folic acid for 21 days.
