The key external characteristics of chicken eggs that should be accurately estimated for various applications in poultry research, food engineering and technology development areas are volume (V) surface area (S), although many researchers often use approximate calculation formulae proposed back the middle last century. These were based on speculative constants prone to computational errors. Us...

The aim of the study was to evaluate effects on exterior and interior egg quality and sensory characteristics of eggs from hens fed diets with admixtures of 3.5 or 7.0% of mussel meal or 20% wheat-distillers dried grains with solubles (DDGS). The mussel meal diets followed organic standards, whereas the DDGS diet was formulated for hens in conventional production. Standard diets, one organic an...

This research was carried out to compare the productivity performance of three lines local quail. The results showed a significant superiority in daily gain weight (3.76 g/day/quail) and marketing (167.2 g/quail) for brown quail over other colors. Also, differences were found dressing ratio between males (67.8%) females (65.76%). As egg production quail, it desert colors number eggs produced, a...

Relationships between egg size, egg components, and neonate size have been investigated across a wide range of oviparous taxa. Differences in egg traits among taxa reflect not only phylogenetic differences, but also interactions between biotic (i.e., maternal resource allocation) and abiotic (i.e. nest environment conditions) factors. We examined relationships between egg mass, egg composition,...

The membrane potential in the blastomeres of dividing Triturus egg cells increases progressively from the first cleavage to the late morula stages. Both the animal and vegetal poles show the same increasing trend in potential; there is no significant potential difference between them. Upon first cell cleavage, the total resistance of the egg cell surface in contact with the exterior decreases t...

AIM The present study was conducted to evaluate the performance of gray, brown, and white varieties of Japanese quail (Coturnix coturnix japonica) with respect to body weight, egg production, and egg quality traits in the coastal climatic condition of Odisha. MATERIALS AND METHODS A total of 500-day-old straight run Japanese quail chicks of three varieties, viz., gray, brown, and white were r...
