This study was to investigate the relationship between chick weight in growing period and laying performance of Korean native chicken (KNC) breeders. We measured body weights 1,384 KNC breeders at 1-140 days age two-week intervals. The first egg laying, hen-day hen-housed production, were investigated. Correlation coefficients production traits analyzed. results showed that correlation signific...

BACKGROUND There is completely no report about both hen egg anti-lipase immunoglobulin yolk (IgY) and its anti-obesity action. Thus, we tried to isolate and characterize a novel anti-lipase immunoglobulin from hen egg yolk. Moreover, we investigated whether hen egg yolk anti-lipase IgY inhibits pancreatic lipase activity in vitro, and examined its ability to prevent obesity in a murine high fat...

The processing of exogenous antigens and the association of peptides with class II molecules both occur within the endocytic pathway. 2A4 B lymphoma cells of the H-2k haplotype were grown in the presence or the absence of two different exogenous antigens (hen egg lysozyme and ribonuclease A) internalized by fluid-phase endocytosis. Using subcellular fractionation techniques, we demonstrate that...

The study was conducted to determine the effect of varying protein levels and preservation method on internal egg qualities of Japanese quails. A total of 180 birds were randomly allotted into three dietary treatments in a completely randomized design (CRD) replicated six times. A factorial arrangement of 3x4x4 which involves 3 protein levels, 4 storage method and 4 time intervals was designed ...

Coronary heart disease (CHD) is the leading cause of death in the United States. Elevated levels of plasma total cholesterol (TC), and particularly plasma low density lipoprotein-cholesterol (LDLC), are primary contributing factors to CHD. Dietary plant sterols (phytosterols) have been shown to significantly reduce plasma TC and LDLC in humans, primarily through inhibition of intestinal cholest...

The effects of 3 different furnished cage systems (Aviplus, Eurovent 625a, Eurovent 625A) on 2 different laying hen strains [Lohmann Selected Leghorn (LSL), Lohmann Brown (LB)] were examined for the traits of production, egg quality, bone strength, claw length, and keel bone status. Two trials were carried out in which all hens received identical feeding and management. In brown hens, the trait...

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....

The objective of this work was to evaluate the inclusion of distillers dried grains with solubles (DDGS) as substitution for soybean meal in Hisex Brown laying hen diets with or without enzyme or vitamin E supplementation on productive performance. A total number of 180 Hisex Brown laying hens at 26 weeks of age were randomly divided into 15 treatment groups in a 5 × 3 factorial design experime...

The influence of dietary oxidized oil was studied on laying hen performance, egg quality and blood metabolites.  Experiment was conducted on 160 laying hens (Hy-Line W-36, 54-61 wk of age) in a completely randomized design with five treatments and four replicated cages containing eight birds per cage. Dietary treatments replaced fresh soybean oil in the control diet (3% fresh soybean oil, 15.25...

As of 2012, the EU has banned the use of conventional cages (CC) for laying hens, causing a shift in housing systems. This study's aim was to gain insight into farmers' opinions on hen health and welfare in their current housing systems. A survey was sent to 218 Belgian egg farmers, of which 127 (58.3%) responded, with 84 still active as egg farmer. Hen welfare tended to be less important in ch...
