in pancreatic survey, quantitative and morphological characteristics could be fundamental variables for the evaluation of some structures. the aim of this study was the application of stereological methods for estimation of quantitative parameters and morphological evaluation of the pancreas in chickens. ten adult male and ten adult female native chickens were used in this study. routine tissue...

An experiment was conducted in Jessore district of Bangladesh during the period from January 2003 to December 2004 to investigate the performance of Brown Shelled Hybrid Layer, White Shelled Hybrid Layer and Native Hen measured during only laying period (57 weeks). 8 Brown Shelled Hybrid Layer farms, 8 White Shelled Hybrid Layer farms and 10 Native Hen farms were reared intensive, intensive and...

this study was conducted to investigate performance of native chickens produced in the centre of production and breeding of native chicken of isfahan in rural areas of isfahan province by using 1440 native pullets with age of 45 days in 4 towns and 2 climate zone of warm and cold. this study employed by coworking 60 rural families that 24 pullets with age of 45 days with ratio of 5 hen to 1 roo...

This study was to investigate the relationship between chick weight in growing period and laying performance of Korean native chicken (KNC) breeders. We measured body weights 1,384 KNC breeders at 1-140 days age two-week intervals. The first egg laying, hen-day hen-housed production, were investigated. Correlation coefficients production traits analyzed. results showed that correlation signific...

The arrival of the dingo in mainland Australia is believed to have caused the extinction of three native vertebrates: the thylacine, the Tasmanian devil and the Tasmanian native hen. The dingo is implicated in these extinctions because, while these three species disappeared during the late Holocene of mainland Australia in the presence of the dingo, they persisted in Tasmania in its absence. Mo...

Salt (NaCl)-extracted nuclear oestrogen receptor from hen oviduct was incubated with salt-depleted oviduct chromatin and dialysed to low salt. The oestrogen receptor (re)associated with chromatin to form a 13-14S-sedimenting fraction, as found in 'native' chromatin, and saturation of this interaction was obtained for very low receptor concentrations (approx. 0.04 nM). Similarly, purified proges...

We use infrared spectroscopy to study the evolution of protein folding intermediate structures on arbitrarily slow time scales by rapidly quenching thermally unfolded hen egg white lysozyme in a glassy matrix, followed by reheating of the protein to refold; upon comparison with differential scanning calorimetric experiments, low-temperature structural changes that precede the formation of energ...
