Ferrous glycinate (Fe-Gly) maintains high bioavailability in animals, but its exact absorption mechanism is still unknown. Here, we studied on the absorption kinetics of ferrous glycinate and its impact on the relevant transport protein in Sprague-Dawley (SD) rats. A total of 72 SD rats (male, BW 100 ± 6.25 g) were randomly allotted to three treatments.(More)
This study was conducted to investigate the effects of zinc sources on gene expression of zinc-related transporters in intestinal porcine epithelial cells (IPEC-1). IPEC-1 cells were treated with zinc glycine chelate (Zn-Gly), zinc methionine (Zn-Met), and zinc sulfate (ZnSO4), respectively, for measurement of cell viability. Then, the relative expression(More)
BACKGROUND Plant extracts have been used widely to improve growth, lower cholesterol, and exert antioxidative defense and antimicrobial activities in animal production. The present study aimed to investigate the effects of dietary phytosterols (PS) on growth performance, antioxidant enzymes and intestinal morphology in weaned piglets. RESULTS A total of(More)
BACKGROUND Phytosterols (PS), plant-derived natural steroid compounds, are novel feed additives to regulate immune function and promote pig growth. This study was conducted to determine the effects of PS on the immune response of weaned piglets. RESULTS One hundred and twenty crossbred (Duroc × Landrace × Yorkshire) piglets with an average initial weight(More)
Due to the penetration of chloride ions, the reinforcement in the pre-stressed concrete structures under marine environment will corroded, which can reduce the durability and safety of the structure. Based on the service features of pre-stressed concrete structure, the structural durability failure criteria of pre-stressed concrete structure under marine(More)
With the development of Internet, as Internet users needed information search tool, the search engine gets more and more users recognition. In order to maximize the sharing of resources, combined with peer network applications, we use P2P technology and lightweight SQLite3 database to research and design an embedded search engine system which is compatible(More)
Rare earth ions (Y<sup>3+</sup>,La<sup>3+</sup>,Nd<sup>3+</sup>) doped TiO<inf>2</inf> catalysts were prepared by the sol-gel method, and characterized by X-ray diffraction (XRD) and UV-vis diffuse reflectance spectroscopy (DRS). The photocatalytic activities of doped TiO<inf>2</inf> were evaluated with methylene blue degradation under UV light. The anatase(More)
The absorption of different iron sources is a trending research topic. Many studies have revealed that organic iron exhibits better bioavailability than inorganic iron, but the concrete underlying mechanism is still unclear. In the present study, we examined the differences in bioavailability of ferrous sulfate and ferrous glycinate in the intestines of SD(More)
