Effect of oat bran, cotton seed hulls and guar gum on chicken egg and blood lipids during the early laying period

Abstract

Fifteen Leghorn pullets were assigned to each of four experimental diets: basal layer ration or basal ration containing 30% oat bran, 3% cotton seed hulls or 0.5% guar gum from 19 to 25 wk of age. Inclusion of oat bran and cotton seed hulls lowered (P < 0.05) egg yolk cholesterol concentration 6 to 7%, but had no significant (P > 0.05) effects on early production parameters. Key words: Chicken, egg, cholesterol, cotton seed hulls, oat bran, guar gum
