This study was designed to extensively characterize the skeletal muscle development in the low weight (LW) quail selected from random bred control (RBC) Japanese quail in order to provide a new avian model of impaired and delayed growth in physically normal animals. The LW line had smaller embryo and body weights than the RBC line in all age groups (P<0.05). During 3 to 42 d post-hatch, the LW ...

Understanding the fate of carbon (C) and nitrogen (N) inputs and outputs from commercial broiler operations is important for increasing the flock C and N efficiency and reducing gaseous emissions. This study was conducted to determine the C and N balance for broiler chickens grown in cages from day old to 42-d market age. Concentrations of ammonia (NH3), methane (CH4), carbon dioxide (CO2) and ...

We show that boundary conditions in topological open string theory on Calabi-Yau manifolds are objects in the derived category of coherent sheaves, as foreseen in the homological mirror symmetry proposal of Kontsevich. Together with conformal field theory considerations, this leads to a precise criterion determining the BPS branes at any point in CY moduli space, completing the proposal of Π-st...

The experimental objective was to evaluate safety of spray-dried plasma protein after oral administration in weanling pigs by monitoring clinical, serological, and performance results. Thirty-six pigs (13.6 kg body weight) were randomly assigned to dietary treatments consisting of control (soybean meal) or 8% plasma. Diets were formulated to contain 1.20% lysine due to continuous administration...

The staphylococcal typing-phage 42 D is propagated on bacteria which are lysogenic for the phage 1363, and the latter phage is present as a contaminant in preparations of phage 42D. This contamination can be avoided by propagating a pure clone of phage 42D on non-lysogenic organisms. Such nonlysogenic propagating strains can be isolated after the lysogenic propagating organisms have been irradi...

This study investigated the effects of feeds naturally contaminated with mycotoxins on growth performance, serum biochemical parameters, carcass traits, and splenic heat shock protein 70 (Hsp70) mRNA expression levels in broiler chickens. The efficacy of yeast cell wall (YCW) adsorbent in preventing mycotoxicosis was also evaluated. Three hundred 1-d-old Arbor Acres broiler chicks were randomly...

Feed restriction strategies are proven to be effective in increasing the growth performance and carcass parameters of broiler chickens. The objective of the present experiment was to evaluate the effects of feedremoval for three hour time periodon growth performance and carcass parameters of relatively older male broiler chickens. Twenty days old male broiler chickens (n=80) were allocated into...

We present a formal model of symmetric n-firm Cournot oligopoly with a heterogeneous population of profit optimizers and imitators. Imitators mimic the output decision of the most successful firms of the previous round a là Vega-Redondo (1997). Optimizers play myopic best response to the opponents’ previous output. The dynamics of the decision rules induce a Markov chain. As expression of bound...
