| Abstract: | Studies were conducted into the quantitative composition of the gastro-intestinal flora of 30 naturally raised piglets in four age groups. The gastro-intestinal tract was found to be "flooded" by Escherichia coli, Clostridium perfringens, micrococci, streptococci, proteus, and lactobacteria over the first hours after birth. Development of the intestinal flora was complete at the age of four days. The groups of germs recordable from naturally and artificially raised piglets were, basically, the same. Piglets, consequently, have no specific "lactoflora". |
