an eight week study was conducted to investigate the effect of inclusion of tomato waste meal in layer diets on laying performance, egg quality and lipid profile as a means to reduce feed cost and pollution. four laying diets containing tomato waste meal (twm) at four levels of 0, 3, 6 or 9% were assigned randomly to 4 groups of 40 birds divided among four replicates of 10 birds in each dietary...

in this study, the effects of culban seed (vicia peregrine l.) on live body weight, feed intake, feed efficiency, egg production, egg quality characteristics, egg yolk fatty acid profiles and yolk cholesterol content in laying hens were investigated. the experiment consists of seven treatment groups with ten replications containing one laying hen in each and for 32 weeks old seventy laying hen ...

the aim of this study was to determine the effect of different dietary levels of walnut leaves powder and vitamin e supplementation on blood antioxidant status, production performance and egg quality characteristics in commercial laying hens. a total number of 216 leghorn hy-line w-36 (70 week old) strain laying hens used the completely randomized design were divided into 6 groups with 3 replic...

The Japanese quail lays eggs with colourful and patterned shells which make the eggshell colour difficult to classify. In this study, the method of measuring colour of patchy eggs using image analyses and its power to discriminate among individual variation were established. Estimated repeatability for egg colour and proportion of patterned areas was high (>0.58), suggesting intermedíate or hig...

The purpose of this study was to evaluate the effect of cholestyramine and lovastatin, lipid-Iowering agents, upon egg quality, reproductive performance, plasma lipids and egg yolk cholesterol levels of Shaver laying hens. Twenty-sixweeks-old hens were fed basal diet without animal products containing 0.2% cholestyramine (COLl), 0.3% cholestyramine (COL2) or 0.005% lovastatin (LOV) for 6 weeks....

OBJECTIVE This experiment investigated the effects of dietary supplementation with conjugated linoleic acid (CLA) on the serum components, laying hen productivity, lipid composition of egg yolk, egg flavor and egg quality. METHODS Healthy 28-week-old Hy-Line white laying hens (n = 480) were divided randomly into 4 groups, 6 replicates/group, 20 birds/replicate. The 30-day experimental diets i...
