摘  要：
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。

摘  要：
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.Piglets in groupⅠ were fed with basal diet,the groupsⅡ and Ⅲ were fed with basal diet supplemented with Saccharomyces cerevisiae(10 mL/d each piglet)and active egg white protein(10mL/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 10days,and the 28-day-old piglets were weaned.On 23,28,35and 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 aseptically 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 groupⅢincreased.Compared to the groupⅠ,cecal butyrate concentration of piglets in group Ⅲ decreased(P<0.01).On 35-day-old,the cecal butyrate concentration of piglets in group Ⅲincreased(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.
