| ABSTRACT The VLDLR gene plays important roles in the growth and adiposity in humans and mice. The purpose of this study was to investigate the relationship between VLDLR gene genetic polymorphisms and growth and abdominal fat traits of the Gaoyou domestic duck. A total of 267 Gaoyou ducks were employed for testing. A 18bp deletion was identified in VLDLR signal peptide coding region. The results of c2 test suggested that the genotype frequencies of VLDLR signal peptide coding region were not in Hardy-Weinberg equilibrium. Least squares analysis showed that body weight (BW) of -18bp/-18bp genotype ducks was significantly higher than those of other genotypes from six (BW6) (p<0.05) to ten weeks of age (BW10) (p<0.01). The association analysis was... |

| ABSTRACT Reticuloendotheliosis virus (REV) infection has frequently affected the poultry industry in recent years. The infection with REV weakens the immune responses of the infected poultry. It is reported that Enteromorphaclathrata polysaccharides are capable of regulating immune function. In order to investigate the immuno regulatory effects of Enteromorphaclathrata polysaccharides (EPS) on the response of REV-infected broilers to a live attenuated Newcastle disease (ND) vaccine. Broilers were intraperitoneally injected with REV at one day of age, subcutaneously infected with EPS at 2 days of age, and vaccinated by nasal drip with a live attenuated ND (Lasota strain) vaccine at 5 days of age. Immune organ index, secretory immunoglobulinA (SIgA),... |
