| Phosphorus is an essential macronutrient for all living plants and plant production. Simultaneously, atmospheric nitrogen deposition also affects plant productivity at a global scale. However, few studies have investigated how plants respond to P addition while simultaneously considering N deposition. We investigated plant biomass, nutrient status and stoichiometric ratios on Potentilla tanacetifolia in response to P fertilization under contrasting N addition rates in a typical meadow steppe in Inner Mongol ia, China. Aboveground biomass of P. tanacetifolia increased under increasing levels of P fertilization under conditions of N addition. However, there was no significant change in biomass when only phosphorus was added. Plant leaf and stem P... |

| ABSTRACT Newcastle disease is a highly contagious disease responsible for major outbreaks and considerable economic losses in the poultry industry in China. There is still little information available regarding gene characterization of the NDV, especially in ducks and pigeons. Therefore, the aim of this study was to investigate NDV isolated from ducks and pigeons in Hubei, China. In this study, three NDVs from ducks and pigeons were isolated between 2013 and 2015.The fusion protein (F) gene of the NDV isolates was sequenced and phylogenetically analyzed. The clinical signs and gross histopathological lesions were examined. Phylogenetic analysis of these strains indicated that all the sequences are classified as genotype II. The isolates shared a 112... |

| ABSTRACT Ovoinhibitor (OIH) is the main proteinase inhibitor in the egg white. In the present study, real-time quantitative PCR and Western-Blot were used to analyze different expression pattern of OIH in ovaries as a candidate gene of reproductive traits in Jingjiang ducks (JJ ducks) and Shaoxing ducks (SX ducks) during three laying stages. To study the polymorphism of the OIH gene in those two duck populations, we designed five pairs of primers to detect SNPs of exon 3-5, 5-6, 14-16 and intron 7, 9 of the OIH gene by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA pool sequencing methods. The results showed that OIH expression increased during the laying stage in the ovaries of both duck breeds. The relative... |

| ABSTRACT The effects of the Kluyveromyces marxianus M3 strain, isolated from Tibetan mushrooms, on plasma lipids, egg cholesterol level, egg quality, and intestinal health of laying hens were evaluated. In total, 160 Beijing fatty laying hens (43 weeks old) were divided into four groups and fed a basal diet supplemented with 0%, 0.1%, 0.3%, or 0.5% freeze-dried K. marxianus M3 powder for four weeks. The results showed that yeast supplementation reduced serum total cholesterol (TC), triglyceride (TG), low density lipoprotein-cholesterol (LDL-C), and very low density lipoprotein-cholesterol (VLDL-C) levels (p<0.01), and increased serum high density lipoprotein-cholesterol (HDL-C) level (p<0.05). Moreover, regardless of K. marxianus M3 dietary addition... |
