Bacterial penetration shortly after inoculation has not been reported extensively. Four strains of bacteria, Salmonella typhimurium (ST), Escherichia coli (EC), Pseudomonas earuginosa (PE) and Stapylococcus aureus (SA), in chicken egg components of Bovan brown were analyzed by serial dilution and scanning electron microscopy. After exposing the fresh eggs to the bacterial strains at concentrati...

This study was carried out to investigate the effects of different breeding systems (breeding on the ground and in the cage) on the egg production and egg characteristics of Rock Partridges. Egg production values of the ground and cage system groups were determined as 41.30 and 49.40%, respectively, and this difference was found to be significant (P < 0.05). The weight values of the eggs were 2...

The quality of Pharaoh quail eggs obtained at 8, 13, 18 and 23 weeks of age was evaluated. Eggs laid by the oldest quail were characterized by the greatest weight (12.2 g), length (32.6 mm), width (25.8 mm) and shell surface area (25.3 cm2). The lowest shell weight was found in eggs from the youngest quail (0.9 g), and the lowest shell proportion (8.2%) was characteristic of eggs from the oldes...

The present study was carried out to determine some egg quality characteristics and storage related changes using computer assisted digital image analysis (CADIA) in an 18-month old moulted brown layer (Lohmann Brown) flock. A total of 150 newly laid eggs was randomly divided into two groups: eggs from the control group were broken immediately, while the remainder were stored at 18 C and 55% RH...

I. The influence of the gut microflora on protein utilization has been investigated with a series of goodand poor-quality protein diets in germ-free (GF) and conventional (CV) chicks by the measurement of net protein utilization (NPU) and uric acid excretion. 2. The diets used were: 280 g protein per kg dict containing unheated or hcat-damaged albumen (roo gjkg), casein (80 g/kg) and gelatin (1...

Mercury contamination of wildlife populations has been documented widely in recent years as biomonitoring has become an important tool for assessing environmental contamination. Avian eggs provide an ideal assay material for Hg biomonitoring, particularly when the collection of eggs is simplified by using cavity-nesting species that nest in easily monitored nest boxes. However, studies are need...

Albumen was removed from broiler eggs before the start of incubation to induce prenatal protein under-nutrition in chicken embryos. With this method, the direct effect of protein deficiency was investigated, differing from mammalian models manipulating the maternal diet where indirect, hormonal effects can interfere. Based on the estimated albumen/egg weight ratio, 10 % of albumen was removed w...

therefore, the objective of this study is to test the feasibility of uv-ir transmission spectroscopy for the non-destructive assessment of the freshness of an individual egg as an alternative for traditional inspection methods. to obtain a considerable variation in freshness, groups consisting of 10 eggs were stored (30 7 oc and 25% 4 rh) for 30 days. data obtained from non-destructive spectral...
