Abstract

Colibacillosis represents a major cause of diarrhea in young rabbits. In order to elucidate protective effect of milk, two experiments were carried out. In the in vitro experiment, rabbit milk treated with lipase significantly decreased the number of viable cells in cultures of Escherichia coli, O128 serotype. The lipase effect was the same with heat-treated and raw milk. In the in vivo experiment, weaned rabbits received feed contaminated with the same bacterium. The course of the infection was moderate. Seven days after inoculation, caprylic acid and triacylglycerols of caprylic and capric acid decreased faecal output of E. coli. At the end of the experiment, average body weights of rabbits receiving caprylic acid and those of non-infected rabbits were not significantly different. It can be concluded that caprylic acid or oils with a high concentration of it may be used as feed supplements for weanlings.
