aCGH Analysis to Estimate Genetic Variations among Domesticated Chickens
Chickens have been familiar to humans since ancient times and have been used not only for culinary purposes but also for cultural purposes including ritual ceremonies and traditional entertainment. The various chicken breeds developed for these purposes often display distinct morphological and/or behavioural traits. For example, the Japanese Shamo is larger and more aggressive than other domest...
متن کاملVariations in Egg-quality Characters in Certain Breeds, Varieties, and Strains of Chickens
Kecent trends in research in the field of egg quaUty have been toward the study of the initial condition of the egg rather than the changes that occur during holding periods under varying environmental influences. Most investigators have concerned themselves largely with the so-called interior egg-quality characters and more particularly with the albumen portions of the egg. Practically all suc...
متن کاملVariations of Phosphorous Accessibility Causing Changes in Microbiome Functions in the Gastrointestinal Tract of Chickens
The chicken gastrointestinal tract (GIT) harbours a complex microbial community, involved in several physiological processes such as host immunomodulation and feed digestion. For the first time, the present study analysed dietary effects on the protein inventory of the microbiome in crop and ceca of broilers. We performed quantitative label-free metaproteomics by using 1-D-gel electrophoresis c...
متن کاملSequential feeding with variations in energy and protein levels improves gait score in meat-type chickens.
Feeding broilers by alternating different diets for 1 or 2 days is known as sequential feeding, and it possibly reduces leg problems since it slows down early growth and may enhance general activity. The present study compared continuous feeding with a standard diet (C: metabolisable energy = 12.55 MJ/kg, crude protein = 190 g/kg) with alternations of a high-energy/low-protein diet (E+P-:+7% ME...
متن کاملShort communication Morphometric variations among five Bhutanese indigenous chickens (Gallus domesticus)
Morphometric characterization provides baseline information for initiating population’s improvement. Thus, the study aims to investigate variations of morphometric traits in five indigenous chickens of Bhutan. A total of 122 adult female birds belonging; Seim (Red Jungle-fowl type), Yuebjha Narp (Black), Khuilay (Naked neck), Phulom (Frizzle) and Shekheni (Short-legged) were included for live w...
