The aim of the study was to assess the influence of shell defects on the quality of eggs after storage. The study material consisted of 1,800 brown-shelled eggs from cage rearing system which were candled on the day of laying to determine the shell quality. Eggs with the 6 most common shell defects ...

In this study, a label-free and double signal Au modified dendritic mesoporous silica nanoparticles (DMSNs/Au) tag modified electrochemical immunosensor were developed and applied for simultaneously detecting ovalbumin from egg white and casein from milk that are likely to exist in ancient wall...

The effect of arginine on the phase stability of the hen egg-white lysozyme (HEWL) has been studied via molecular dynamics computer simulations, as well as experimentally via cloud-point temperature determination. The experiments show that the addition of arginine increases the stability of the...

An experiment feeding three concentrations of betaine was conducted using breeding geese to analyse the reproductive performance, serum biochemical indexes, egg quality and intestinal immunity. A total of 450 female and 90 male Jiangnan White breeding geese were divided into three treatments, with...

Experimental selection of Puskinskaya universal chicken breed for increased weight and proportion of egg yolk was performed. After only one generation of the selection the significant desirable changes in egg yolk size were found: the average proportion of yolk was increased by 0.8% (from 26.6±0.08 ...

Phospholipids including lecithin are the structural components of plant and animal cell membranes actively participating in many biochemical processes underlying growth and development. Lecithin is known to positively affect metabolism of lipids, protein and minerals in poultry which, in turn, can...

Minerals are used widely as feed additives in the diets of poultry to enhance bone and egg quality and productivity. Therefore, the current study aimed to evaluate the impact of strontium ranelate and cerium oxide addition in the diet on egg production and eggshell quality in laying hens. In this...

The feeding value of rice-based distillers dried grains with solubles (r-DDGS) was evaluated in the diet of laying chickens. A total of 4752, 24-weeks old laying chickens were divided at random into three groups having 18 replicates consisting of 88 birds in each. The experimental diets were...

Selenium is an essential trace mineral element to maintain animal health, and plays an important role in the physiological processes of antioxidant, immune response, growth, development and reproduction. Selenium exists in animal organisms mainly in the form of selenium protein and is an important...

The profitability of pheasants breeding is influenced by many factors, but eggs quality is considered as the backbone for successful pheasant breeding. The objective of this study was to determine and compare various quality characteristics (physical, morphological, and mechanical) of eggs from...
