We present high-resolution X-ray spectra of the nearby, multiple T Tauri star (TTS) system Hen 3-600, obtained with the High Energy Transmission Grating Spectrograph (HETGS) aboard the Chandra X-ray Observatory (CXO). Both principle binary components of Hen 3-600 (A and B, separation 1.4) were detected in the zeroth-order CXO/HETGS X-ray image. Hen 3-600-A — the component with a large mid-infra...

<p><strong>Background. </strong>Poultry production is a tool for livelihood improvement and poverty alleviation in the developing countries. Indigenous chickens are numerous but lower egg performance than exotic Ethiopia. <strong>Objective</strong>. To compare yield, feed conversion ratio (FCR), mortality, quality traits of Normal feathered local (LL), Sasso-RIR (S...

Hen antigonococcal lipopolysaccharide hen serum was used in a simple slide agglutination test for the identification of Neisseria gonorrhoeae from primary isolates.

In this article, we present the continuing work on a SARS model without quarantine by Hsu and Hsieh [Sze-Bi Hsu, Ying-Hen Hsieh, Modeling intervention measures and severity-dependent public response during severe acute respiratory syndrome outbreak, SIAM J. Appl. Math. 66 (2006) 627–647]. An “acting basic reproductive number” ψ is used to predict the final size of the susceptible population. We...

In a recent account of methods of obtaining best-fit parameters of the parameters V and Km of the Michaelis-Menten equation, Tseng & Hsu (1990) appear to have misunderstood the method used by Lineweaver & Burk (1934), and to have overlooked much of the work done since 1934. The Michaelis-Menten equation represents the observed rate of v of an enzyme-catalysed reaction in terms of the two parame...

A study was conducted to determine the requirement for lysine of a White Leghorn strain of hens with a body weight of approximately 1,600 g. Before starting the experiment, apparent fecal digestibility of amino acids of the basal diet was determined in an in vivo digestibility trial with six individually housed hens. The basal diet used was based on corn and soybean meal and contained 0.65% tot...

An experiment was conducted with 72 Bovans Brown laying hens to determine the effect of dietary crude glycerin on laying performance; egg quality; retention of N, Ca, and P; and metabolizability of energy. The dietary treatments consisted of a control corn-soybean diet containing 6% corn starch (17% CP, 2,775 kcal/kg of AME(n), 0.81% lysine, 0.36% methionine, 3.60% Ca, and 0.37% available P) an...

This study was conducted to evaluate the effects of replacing maize in quail diets with graded levels of rumen filtrate-fermented cassava meal (FCM) on growth and egg production performances. Cassava meal (CM) was mixed with dried manure of layer at 75 g/kg CM, which was mixed with freshly collected rumen filtrate (at 1 L/5 kg CM), and finally fermented in sealed bags for 14 days. It was then s...

The Impact of Supplemental L-Threonine in Laying Hen Diets on Egg Component Yield, Composition, and Functionality. (August 2005) Paige Reynolds Niemeyer, B.S., Texas A&M University; M.S., Texas A&M University Chair of Advisory Committee: Dr. John Carey The impacts of supplemental L-threonine in laying hen diets were evaluated. Over three experiments, control hens were fed a corn-soybean commerc...

The purpose of the present study is to get a better knowledge of the Malagasy indigenous race of hen through its egg physical characteristics and its laying performance in order to promote villager poultry production. This study was undertaken within a local family farm, of the rural Township of Ambalamahasoa, Haute Matsiatra Region, Madagascar, with 25 hens and 4 roosters in age to reproduce. ...
