A chicken egg is an already packaged food. An important quality aspect of the packaging material is the mechanical strength of the eggshell. A commonly used technique for the measurement of the shell strength is the quasi-static, non-destructive compression of an egg between two parallel steel plates. The slope of the force-deformation curve is a measure for the stiffness of the shell and for t...
In this study, it was aimed to determine the internal and external quality traits of the Guinea fowl eggs as well as the phenotypic correlation among the these traits. Totally 100 Guinea fowl eggs were collected in three sequential days were used for this study. The birds were housed at Poultry Research Unit of the Department of Animal Science, Faculty of Agriculture, University of Akdeniz. Val...
This trial was conducted to evaluate the effects of high-dose daidzein supplements on laying performance, egg quality and antioxidation in laying hens during the late laying period. Seven hundred sixty eight 55-wk-old Hyline Brown were randomly assigned to four groups with 8 replicates of 24 birds each (192 laying hens per group) and fed diets supplemented with 0 (control), 10mg/kg, 50mg/kg and...
The organic component of the avian eggshell can be divided into 3 portions, the shell membranes, the matrix and the cuticle. These have been well characterised in the chicken but little has been published with regard to the ostrich (Struthio camelus). A number of recent studies have indicated that the cause of intra-shell embryonic deaths in the ostrich is similar to intra-shell embryonic death...
Research at 10 locations in coastal subtropical Queensland, Australia, has shown that salt marshes contained heterogeneous distributions of eggshells of the pest and vector mosquito Aedes vigilax (Skuse) (Diptera:Culicidae). The eggshell distribution was related to specific vegetation assemblages, with a mix of the grass, Sporobolus virginicus (L.) Kunth (Poales: Poaceae), and the beaded glassw...
Abstract The aim of this study was to evaluate and compare the impact genotype storage conditions (temperature time) on microbiological contamination eggshell quality. There were four genotypes laying hens used, Czech Golden Spotted (CGS), Greenleg Partridge (GP), White Leghorn (WL) commercial hybrid (CH) included. After collection, eggs divided equally into five groups according time (0, 14, 2...
Model peptides were designed, synthesized and conducted a detailed structure-property study to unravel the molecular mechanism of goose eggshell calcification. The peptides were designed based on the primary structural features of the eggshell matrix proteins ansocalcin and OC-17. In vitro CaCO3 crystal growth experiments in presence of these peptides showed calcite crystal aggregation as obser...
background: this study aimed to assess the relationship between meal frequency with mental distress and violent behavior among a nationally representative sample of iranian children and adolescents. materials and methods: the participants of this national study were 14,880 iranian students with 6 to 18 years of age. they were selected from urban and rural regions of iran by multi-stage cluster ...
