An experiment is conducted to investigate the effects of selenium (Se) source and level on growth performance, tissue Se concentrations, antioxidation, and immune functions of heat-stressed broilers from 22 to 42 days of age. A total of 210 22-day-old Arbor Acres commercial male chicks were assigned by body weight to one of seven treatments with six(More)
Service-oriented business ecosystem (SOBE) is a relatively new paradigm for the development of service-oriented enterprises (SOEs). It tries to operate and reorganize business services provided by enterprises as business ecosystems in analogy with the way that natural ecosystems are running on. Business ecosystem is composed of diverse business services(More)
An experiment was conducted to investigate the bioavailability of organic manganese proteinate (Mn) relative to inorganic Mn sulfate for broilers fed a conventional corn–soybean meal basal diet. A total of 448-day-old Arbor Acres commercial male chicks were fed the Mn-unsupplemented basal diet (control) or basal diet supplemented with 60, 120, or 180 mg(More)
Two experiments were conducted to investigate the kinetics of manganese (Mn) transport in Caco-2 cell monolayers and the gene expressions of Mn transport carriers in apical (AP) and basolateral (BL) membranes. In experiment 1, the cells were treated with the medium containing 146 μmol/L of Mn (MnSO4·H2O). Both the uptake and transport of Mn from AP–BL or(More)
An experiment was conducted to investigate the bioavailability of organic copper (Cu) proteinate relative to inorganic Cu sulfate for broiler chicks fed a conventional corn–soybean meal basal diet. A total of 320 day-old Arbor Acres commercial male chicks were assigned to one of five treatments in a completely randomized design involving a 2 × 2 factorial(More)
The objective of this study was to develop a procedure for estimating the standardized mineral (calcium, Ca; phosphorus, P; copper, Cu; manganese, Mn; zinc, Zn) availabilities (SMA) in soybean meal for broilers. In experiment 1, twelve 24-day-old male chicks were used to determine the length of the pre-experimental fasting period needed to empty the total(More)
An experiment was conducted to investigate the effect of phytase transgenic corn (PTC) on intestinal microflora, and the fate of transgenic DNA and protein in the digesta and tissues of broilers. A total of 160 1-day-old Arbor Acres commercial male broilers were randomly assigned to 20 cages (8 chicks per cage) with 10 cages (replicates) for each treatment.(More)
