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.
采用正常和切除盲肠的产蛋母鸡，研究肠道（盲肠）菌群及嗜酸乳杆菌植入对血清和蛋黄胆固醇水平的影响。实验鸡16月龄时通过手术切除盲肠。切除盲肠的产蛋母鸡血清胆固醇水平高于正常鸡；嗜酸乳杆菌植入使正常和切除盲肠的鸡血清胆固醇水平均显著降低。正常肠道（盲肠）菌群和嗜酸乳杆菌植入不影响脂肪消化率。切除盲肠的鸡的蛋黄胆固醇水平较高。未观察到血清和蛋黄胆固醇之间存在恒定关系。
