Two experiments were conducted to estimate the digestibility of energy, nitrogen and amino acids (AA) in growing pigs fed diets containing one of five corn distillers' dried grains with solubles (DDGS), including three normal oil DDGS (NO-DDGS) and two low oil DDGS (LO-DDGS) samples. Exp. 1 was conducted to determine the digestible energy (DE) and(More)
It has been widely documented that fish oil attenuates inflammatory responses partially via down-regulation of T-lymphocyte function. To determine the anti-inflammatory role of fish oil in weanling pigs, we investigated the effects of fish oil and its functional constituents on peripheral blood lymphocyte proliferation, cytokine production and subsequent(More)
The deposition profile of melamine was studied in eggs obtained from laying hens fed melamine contaminated feed. A total of 180 laying hens were divided into five groups and were fed diets spiked with 0, 5, 25, 50, or 100 mg of melamine per kg of feed. Eggs collected on days 1, 3, 5, 7, 9, 11, 13, and 15 were analyzed by a gas chromatography-mass(More)
Melamine is a chemical product that was sporadically mixed into animal feeds to boost protein content. Excessive melamine in animal feed can induce renal failure and even death in animals. The residue of melamine in edible animal products also threatens human health. Currently, there is no real-time and high throughput method to detect residual melamine in(More)
Two experiments were conducted to evaluate the effects of live yeast supplementation on performance, nutrient digestibility, enteric microbial populations and volatile fatty acid (VFA) concentration of weanling pigs, receiving diets supplemented with aureomycin and elevated doses of CuSO4. In experiment 1, 90 crossbred pigs (7.20 +/- 0.44 kg, 28 d of age)(More)
OBJECTIVE To measure and compare the content of d-borneol in the different parts of Cinnamomum camphora by GC-MS. METHOD With water-steam distillation and GC-MS method, d-borneol was extracted and determined. RESULT The linear range of d-borneol was 0.4-2.8 microg (r = 0.999 9). The average recovery was 95.40%, and RSD was 0.56%. CONCLUSION The method(More)
This study was designed to evaluate the efficacy of DL-selenomethionine (DL-SeMet) supplementation on growth performance, antioxidant status, plasma selenium (Se) concentration, and immune function of weaning pigs. 216 weaning pigs were randomly allocated to 6 treatments with 6 replicates each according to a complete randomized block design. Each replicate(More)
Three experiments were conducted to study the property of xylanase and the effects of xylanase in wheat-based diets on growth performance of broilers, respectively. Experiment 1 was performed in vitro to evaluate the effect of different pH and temperature on xylanase activity, and to evaluate the enzymic stability under different conditions. The results(More)
Yuzhu (Polygonati Odorati Rhizoma), Kangdingyuzhu (Polygonati Prattii Rhizoma), and zhugenqiyuzhu (Disporopsis Fuscopictae Rhizoma) are of the same family, but of different genera. They have all often used in Chinese Materia Medica (CMM) as Polygonati Odorati Rhizoma in China market. Three species of CMM are confused. For better application, we need to(More)
