Abstract
Pigs and chickens were fed diets containing increased concentrations of the single cell protein (SCP), Pruteen, in order to investigate the effects of a diet containing high levels of nucleic acids on the activity of DNase in intestinal contents. Increased levels of SCP in the diet generally resulted in increased DNase activity in intestinal contents. Significant differences at P≦0.05, were found between the control groups and most of the experimental groups in both species. With the exception of the 2 groups given the highest levels of SCP in the chicken experiment, the DNases in the large intestines were not inhibited by antisera produced against DNase in pancreatic juice.
摘要
用含有浓度递增的单细胞蛋白（SCP）——普鲁顿的日粮饲喂猪和鸡，以研究含高核酸水平的日粮对肠内容物中脱氧核糖核酸酶（DNase）活性的影响。日粮中SCP水平的提高通常会导致肠内容物中DNase活性增强。在两个物种的对照组和大多数实验组之间均发现了P≤0.05水平的显著差异。在鸡的实验中，除了给予最高SCP水平的两组外，大肠中的DNase未被针对胰液中DNase产生的抗血清所抑制。
