The gene encoding the oligopeptide transporter PepT1 (HGMW-approved gene symbol SLC15A1) from Tibetan porcine intestine was cloned. The open reading frame of this cDNA encodes 708 deduced amino acid residues that show high sequence similarity with its ovine and bovine counterparts. The putative protein has 12 putative transmembrane domains, including many(More)
The nutrient digestibility and feeding value of rapeseed meal (RSM) for non-ruminant animals is poor due to the presence of anti-nutritional substances such as glucosinolate, phytic acid, crude fiber etc. In the present study, a solid state fermentation (SSF) using Aspergillus niger was carried out with the purpose of improving the nutritional quality of(More)
The small intestine is the main absorption place of peptides and free amino acids in mammals. The amino acid transporter system b(0,+) mediates apical uptake of basic amino acids, especially lysine, arginine and cysteine. The aim of the current study was to clone Tibetan porcine amino acid transporter b(0,+)AT (SLC7A9) for comparing the sequences of Tibetan(More)
Rapeseed cake is a good source of protein for animal feed but its utilization is limited due to the presence of anti-nutritional substances, such as glucosinolates (Gls), phytic acid, tannins etc. In the present study, a solid state fermentation (SSF) using Aspergillus niger was carried out with the purpose of degrading glucosinolates and improving the(More)
The aim of the present study was to investigate the influences of Aspergillus niger fermented rapeseed meal (FRSM) on growth performance and nutrient digestibility of growing pigs. A total of 72 growing pigs (body weight = 40.8 ± 2.1 kg) were used in feeding trials, lasting for up to 42 days, and were randomly allotted to one of three diets, including a(More)
Corn and soybean meal (SBM) are two of the most common feed ingredients used in pig feeds. However, a variety of antinutritional factors (ANFs) present in corn and SBM can interfere with the bioavailability of nutrients and have negative health effects on the pigs. In the present study, two-stage fermentation using Bacillus subtilis followed by Enterococcus(More)
Shiga toxin-producing Escherichia coli (STEC) is recognized as an important human diarrheal pathogen. Swine plays an important role as a carrier of this pathogen. In this study we determined the prevalence and characteristics of STEC from healthy swine collected between May 2011 and August 2012 from 3 cities/provinces in China. A total of 1003 samples,(More)
