The influence of intestinal (ceca) flora on serum and egg yolk cholesterol levels in laying hens. 1975

F Tortuero, and A Brenes, and J Riopérez

Normal and cecectomized laying hens were used to study the influence of intestinal (ceca) flora and the implantation of Lactobacillus acidophylus on the levels of serum and egg yolk cholesterol. The ceca had been surgically removed when the experimental birds were 16 months of age. Serum cholesterol levels of cecectomized laying hens were higher than that of normal birds; the Lactobacillus acidophylus implantation resulted in a significant decrease in serum cholesterol levels in both normal and cecectomized birds. The normal intestinal (ceca) flora and Lactobacillus acidophylus implantation did not influence fat digestibility. Egg yolk cholesterol levels were higher for cecectomized birds. A constant relationship between serum and egg yolk cholesterol was not observed.
