为研究活化卵白蛋白对早期断奶仔猪盲肠内挥发性脂肪酸（VFA）含量的影响，选取54头20日龄健康仔猪，随机分为3个处理组，Ⅰ组饲喂基础日粮，Ⅱ组、Ⅲ组在基础日粮中分别添加啤酒酵母10mL/（d·头）、活化卵白蛋白10mL/（d·头）。仔猪23日龄时开始口服制剂，连续10d，并于28日龄断奶。仔猪23、28、35、42日龄时，分别从每个重复中随机选1头屠宰，迅速结扎盲肠两端，无菌收集盲肠食糜，利用气相色谱法测定盲肠内VFA含量。结果显示：仔猪42日龄时，与Ⅰ组、Ⅱ组相比，Ⅲ组仔猪盲肠内乙酸（P＜0．01）、丙酸（P＜0．01）、戊酸（P＜0．01）、总VFA（P＜0.05）、异丁酸含量升高（P＞0．05）；与Ⅰ组相比，Ⅲ组丁酸含量下降（P＜0．01）；仔猪35日龄时，与Ⅰ组、Ⅱ组相比，Ⅲ组仔猪盲肠内丁酸含量升高（P＜0．01）。表明活化卵白蛋白可以提高早期断奶仔猪盲肠内VFA含量。

To investigate the effects of active egg white protein on cecal volatile fatty acid (VFA) of early weaned piglets ,fifty four 20-day-old piglets were randomly divided into three groups .Pig-lets in group Ⅰ were fed with basal diet ,the groups Ⅱ and Ⅲ were fed with basal diet supple-mented with Saccharomyces cerevisiae (10 mL/d each piglet ) and active egg white protein (10 mL/d each piglet ) ,respectively .The 23-day-old piglets in group Ⅱ and group Ⅲ were fed with Saccharomyces cerevisiae and active egg white protein for 10 days ,and the 28-day-old piglets were weaned .On 23 ,28 ,35 and 42-day-old ,one piglet randomly selected from each replication was slaughtered ,both ends of cecum were ligated quickly and the cecal digesta were collected aseptic-ally to determine the cecal volatile fatty acid by gas chromatography .The results showed that compared to the groupsⅠand Ⅱ on 42-day-old ,the concentrations of the cecal acetic acid (P<0.01) ,propionic acid(P<0 .01) ,valeric acid(P<0 .01) ,isobutyric acid concentration(P>0 .05) and total VFA (P<0 .05) of piglets in group Ⅲ increased .Compared to the group Ⅰ ,cecal buty-rate concentration of piglets in group Ⅲ decreased(P<0 .01) .On 35-day-old ,the cecal butyrate concentration of piglets in group Ⅲ increased(P<0 .01) compared with the group Ⅰand groupⅡ .It indicates that the active egg white protein could improve cecal VFA concentration of early weaned piglets .
