Plasma cholesterol levels in rabbits fed low fat, low cholesterol diets Effects of dietary proteins, carbohydrates and fibre from different sources

摘要: Rabbits become hypercholesterolemic when transferred from commercial feed to a low fat, cholesterol-free semisynthetic diet. The role of different dietary components in mediating this effect was investigated by varying the composition diet and commerical feed. Addition alfalfa prevented normal response, but other plant products, including several with high fibre content, were ineffective. Increasing content powdered cellulose appeared enhance response. A commercially formulated which soybean meal replaced ground corn oats did not produce significant elevation plasma cholesterol. Substitution sugars or starches for dextrose gave variable results, those tested, only potato starch hypercholesterolemia. type protein used had marked influence on level Semisynthetic diets containing proteins animal sources higher cholesterol levels than sources. Very obtained choline soy isolate, supplementation methionine raised that normally Replacement salt mixture one specially recommended rabbits made no difference Prevention coprophagy significantly affect either diets. Growth performance generally better there direct correlation between weight gain
