实验研究了饲粮不同粗蛋白水平对断奶仔猪肠黏膜形态和肠道健康状况的影响.实验采用完全随机设计,将72头28日龄断奶的仔猪分为4组,每组3个重复,每个重复6头.4个组分别接受24%、22%、20%、18%蛋白水平的日粮.结果表明,采食粗蛋白水平为24%的日粮使小肠不同肠段绒毛的生长受到了抑制,使隐窝加深、绒毛/隐窝比降低;随着日粮粗蛋白水平的下降,回肠和盲肠消化物pH、氨氮浓度显著降低(P

The experiment was conducted to evaluate the effects of dietary protein content of weaned pigs on intestinal morphology and intestinal health. This experiment was in a complete randomized design. 72 healthy piglets were divided into four groups with three replicates, each of which including 6 piglets. The four groups were offered diets containing 24 % ,22 % ,20 % and 18 % CP respectively. The results showed that A dietary CP concentration of 24 % inhibited villous growth, deepened crypt depth and decreased VH ： CD in the intestinal tract. The ...
