This study investigates the influence of litter provision and linings used for nests and pecking and scratching areas on cage hygiene, laying location, and egg quality. Research was carried out in furnished cages, each housing 60 beak-trimmed ISA Brown hens. Four different treatments were compared in a factorial arrangement, including 2 different nest linings (artificial turf vs. plastic mesh),...

Loss of shell colour in brown-egg layers is a shell quality issue in Australia and is periodically associated with free range egg production. This study investigated the loss of shell colour that occurs in some flocks of free range laying hens. Hens laying pale-coloured egg shells on a commercial free range farm were transferred to cages in an experimental facility. Egg quality was measured imm...

Received at: 16/5/2015 Accepted: 15/6/2015 Storage of table eggs in refrigeration is a popular habit but it may be lead to different degree of contamination with pathogens and increase the risks of illness in humans. A total of 75 chicken table eggs (grades II) were collected from 5 farms (15 of each) in Alexandria province and which were stored in refrigerator at 5 °C. The collected eggs were ...

Even though the laying hen industry in Kuwait is one of the most important animal industries, it covers only 55% of local egg consumption, and the remainder is imported resulting in increase in egg prices. In addition, a major problem that the egg industry is facing is the low quality of the eggshells, resulting in a large loss to the industry. Therefore, it is important to use a strain of layi...

This study was designed to evaluate efficacy of polyherbal hypocholesterolemic supplement AV/HLP/16 (test compound) on serum and egg yolk cholesterol levels and egg quality parameters in layers. One hundred and twenty healthy White Leghorn (BV 300 strain) of 54 weeks age were randomly divided into four treatments (T 0 , T 1 , T 2 , T 3 ); subdivided into three replicates with ten birds in each ...

A series of incubation and broiler growth studies were conducted using one strain of broiler chicken (fast feathering dam line) observing incubation effects on femoral bone ash % at hatch and the ability of the bird to remain standing at 6 weeks of age (Latency-To-Lie). Egg shell temperatures during incubation were consistently recorded. Parsimonious models were developed across eight studies u...

The aim of the study was to evaluate egg shell quality characteristics, mineral content in the egg shell, and serum mineral concentration during the egg formation process as influenced by oviposition time and ambient temperature at the beginning and end of the laying cycle in laying hens and broiler breeders. Egg shell quality deteriorated significantly at the higher temperature and was lower i...
