Hy-Line W98, W36, and Brown hens are among the most popular strains for commercial egg production. It is of interest to evaluate the differences in performance of old hens of each variety. As part of a larger study, hens of the three varieties were maintained under production longer than 100 weeks of age and hens of each strain were randomly selected for in vitro calcium uptake (CaT) by duodena...

Teh ultrasound-assisted magnetic stirrer was used as an effective extraction technique for teh evaluation of total phenolic contents (TPC) and antioxidant potential of ten Pakistani brown rice cultivars. For this purpose, ultrasonic (240W frequency 50/60 Hertz) assisted magnetic stirrer coupled with three solvents methanol, ethanol, and isopropanol in pure and aqueous fractions (80:20) were...

The present study investigated whether the same temperature-humidity index (THI) values under different conditions of air temperature and relative humidity (RH) would affect thermoregulatory, nutritional, behavioral responses laying hens. One hundred twenty Hy-Line Brown hens (60-weeks-old) were divided equally in two environmental chambers: 26 °C with 70% RH (hRH75) 30 30% (hT75) for 28 days. ...

We present high-resolution optical spectroscopy of four candidate members of the nearby TW Hydrae young association including three brown dwarfs (2MASS 1207-3932, 2MASS 1139-3159 and TWA 5B) and one T Tauri multiple star (TWA 5A). Using echelle spectra from the Magellan Baade 6.5-meter telescope, we confirm the pre-main sequence status and cluster membership of the substellar candidates , throu...

Different members of the TAF family of proteins work in differentiated cells, such as motor neurons or brown fat cells, to control the expression of genes that are specific to each cell type.

We incubated 196 large-diameter aspen (Populus tremuloides), birch (Betula papyrifera), and pine (Pinus taeda) logs on the FACE Wood Decomposition Experiment encompassing eight climatically-distinct forest sites in United States. sampled dead wood from these after 2 to 6 y of decomposition determined rot type as a continuous variable using lignin loss/density loss ratio (L/D) assessed wood-rott...

the present research is aimed at investigating how the politeness of the speakers of urdu is influenced by their relative social status in society. the researcher took politeness theory of brown and levinson (1978, 1987) as a model. to observe politeness of urdu speakers, speech act of apology with different strategies was selected. a discourse completion task (dct) was used as an instrument to...

Previously we showed that free-range hens fed diets supplemented with diatomaceous earth (DE) were significantly heavier, laid more eggs, and consumed more feed than hens fed the control diet, with no differences in feed efficiency. In the present study, we compared plasma calcium concentrations, and bone mineralization of the hens from our previous study to test the effect of DE on these param...
