摘要本试验旨在研究饲粮粗蛋白质水平对断奶仔猪消化能力、结肠氨氮（AN）含量和结肠炎症损伤的影响。选取96头25日龄断奶的杜×长×大三元杂交仔猪，适应饲养7 d后随机分成4组，分别饲喂18%、20%、22%和24%粗蛋白质水平的饲粮，并于饲喂后6、24、48、72和96 h，每组选择4头仔猪前腔静脉采血后屠宰，采样测定胃内容物pH，胃蛋白酶和十二指肠糜蛋白酶活性，结肠AN、血清和结肠白细胞介素（IL）-1β和IL-10含量。结果表明：1）饲粮粗蛋白质水平对断奶仔猪生长性能无显著影响（P>0.05）。2）除饲喂后48 h外，其余时间点24%粗蛋白质组仔猪胃内容物pH均显著或极显著高于20%粗蛋白质组（P<0.05或P<0.01）；在整个试验期，24%粗蛋白质组仔猪胃蛋白酶、十二指肠糜蛋白酶活性均低于20%粗蛋白质组，其中胃蛋白酶活性在6、72 h时有显著差异（P<0.05），十二指肠糜蛋白酶活性在24、48 h时有显著差异（P<0.05）。3）除饲喂后6 h外，其余时间点24%粗蛋白质组仔猪结肠AN含量均高于18%、20%粗蛋白质组，在24、72 h时有显著或极显著差异（P<0.05或P<0.01）。4）24%粗蛋白质组仔猪结肠IL-1β含量在24~96 h时均显著或极显著高于20%粗蛋白质组（P<0.05或P<0.01）；在整个试验期内，24%粗蛋白质组结肠IL-10含量均低于20%粗蛋白质组，在24、72 h时有显著或极显著差异（P<0.05或P<0.01）。5）相关性分析发现，胃糜蛋白酶活性与结肠AN含量之间呈极显著负相关（P<0.01），结肠AN含量与IL-1β含量、结肠IL-1β与IL-10含量间分别呈显著正相关和负相关（P<0.05）。综上，给断奶仔猪饲喂20%粗蛋白质水平饲粮可通过降低仔猪胃内容物pH、升高胃蛋白酶和十二指肠糜蛋白酶活性来降低结肠AN含量，并降低结肠IL-1β含量、升高IL-10含量，从而减少结肠炎症损伤。

Abstract：To investigate the effects of dietary crude protein (CP) level on digestive ability, colonic ammonia nitrogen (AN) content and inflammatory injury of colon of weaned piglets, ninety-six 25-day-old weaned piglets were selected and randomly divided into four groups after 7 days of adaptive feeding. The piglets were fed diets with 18%, 20%, 22% and 24% CP levels, respectively. Four piglets were selected in each group, and collected blood and slaughtered after feeding 6, 24, 48, 72 and 96 h. The samples were used for measuring pH, pepsin and duodenal chymotrypsin activities, colonic AN content, interleukin (IL)-1β and IL-10 contents in serum and colon. The results showed as follows:1) dietary CP levels had no significant effect on growth performance of weaned piglets (P>0.05). 2) The pH in gastric contents in 24% CP group was significantly higher than that in 20% CP group (P<0.05 or P<0.01) except for feeding 48 h; the activities of pepsin and duodenal chymotrypsin in 24% CP group were lower than those in 20% CP group during the whole experiment period:the difference in activity of pepsin was significant at 6 and 72 h (P<0.05), and the difference in activity of duodenal chymotrypsin was significant at 24 and 48 h (P<0.05). 3) The content of AN in colon in 24% CP group was higher than that in 18% and 20% CP groups during the experiment except for feeding 6 h, and the difference was significant at 24 and 72 h (P<0.05 or P<0.01). 4) The colonic IL-1β content in 24% CP group was significantly higher than that in 20% CP group at 26 to 96 h (P<0.05 or P<0.01). During the whole experiment period, the colonic IL-10 content in 24% CP group was lower than that in 20% CP group, and the difference was significant at 24 and 72 h (P<0.05 or P<0.01). 5) The correlation analysis showed that there was a significant negative correlation between chymotrypsin activity and AN content in colon (P<0.01), significant positive and negative correlation between AN and IL-1β contents in colon, IL-1β and IL-10 contents in colon, respectively (P<0.05). In conclusion, feeding the diet with 20% CP level to weaned piglets can reduce the content of AN in colon by increasing the activity of chymotrypsin, and decrease the content of IL-1β, increase content of IL-10 in colon, thus reducing the inflammatory injury of colon of weaned piglets.
