摘要
选用288只1日龄新扬州雏鸡,随机分成4组,每组3个重复,分别饲喂在基础日粮中添加4种水平核黄素(0、3.6、7.2、14.4mg/kg)的日粮,探讨日粮添加核黄素对28日龄雏鸡铁吸收和储存能力的影响。试验期为28d。结果表明:(1)雏鸡的腺胃、十二指肠、空肠、回肠和胫骨组织中铁含量均有随核黄素添加量增加而增加趋势,但差异均不显著(P<0.05)。(2)不同组织中铁吸收储存能力大小排序为:十二指肠>空肠>胫骨>腺胃>回肠。因此,日粮中添加核黄素能够一定程度上促进新扬州雏鸡铁吸收和储存。
The effects of dietary riboflavin supplementations on iron absorption and accumulation of New Yangzhou chickens were investigated.288 1 day-old chickens were randomly divided into 4 groups and 3 replicates for each group, which were fed diets supplemented with 4 different levels of riboflavin (0,3.6.7.2 mg/kg and 14.4 mg/kg)respectively.The experiment period was 28 days.The results showed that: (1)The iron contents of glandular stomach,duodenum,jejunum, ileum and tibia had an increasing tendency with the increase of riboflavin supplementations (P 〈 0.05). (2)The sequence of iron absorption and accumulation ability were:duodenum 〉 jejunum 〉 tibia 〉 glandular stomach 〉 ileum.It was concluded that the dietary riboflavin supplementations could enhance the iron absorption and accumulation of New Yangzhou chickens.
