日粮NDF水平对断奶獭兔肠道形态及MUC1、MUC2基因表达的影响

Effects of Diets NDF Levels on Intestinal Morphology and Expression of MUC1,MUC2 in Intestine of Weaned Rabbits

为了评估不同水平NDF日粮对断奶獭兔肠道形态及MUC1、MUC2基因表达的影响,选取56只35天断奶獭兔,随机均分为4组,每组14只,每只为1个重复,单笼饲养。5天预饲期,28天正式饲喂,饲喂期间正常免疫和消毒,并使其自由饮水和采食。饲养完成后各组随机选择6只屠宰,采集十二指肠、空肠、回肠、盲肠样品进行测定。结果表明幼龄獭兔十二指肠与回肠是病变感染易发区;33%NDF水平的日粮有益于肠道健康。

The objective of the present study was conducted to study the effect of diet NDF level on intestinalmorphology and expression of MUC1,MUC2 in intestine of weaned rabbits. In experiments 56 weaned youngrabbits at 35 days were selected,randomly divided into 4 groups. The experiment composed of 5 days pre trailand 28 days experiment period. During the period of feeding,rabbits dormitory was immuned and disinfectednormally and rabbits were allowed to drink and eat freely.At the end of the experiment,6 rabbits were slaugh-tered in each group to collect duodenum,jejunum,ileum,cecum samples to determine. The results indicatedthat rex rabbit's duodenum and ileum were prone to infection; the 33% NDF ration was helpful to make a goodintestinal environment.
