In addition to Coleman’s theory of social capital in explaining family background on children’s educational achievement, researchers also hypothesized the mediating mechanisms being (1) deprivation of economic resources, (2) lesser parental involvement and monitoring in children’s education, and (3) fewer network ties to obtain information and other supports related to learning. Indeed, strong ...

The objectives of this study were to determine whether intestinal viscosity caused by mixed linked barley beta-glucan depresses ileal nutrient digestibility and digestive enzyme activities and to determine the interaction of intestinal viscosity, digestive enzyme activities and ileal nutrient digestibility in different ages of poultry. In Experiments 1 and 2, 1-d-old broiler chicks and 1-y-old ...

  A total of 60 neck skin swab samples were taken from 12 different broiler flocks after the chilling stage of processing at a commercial broiler slughtering facility in Mashhad. The presence of Salmonella was assessed by conventional culture method and confirmed by using poly O and poly H antiserum in serotyping. PCR amplification of invA gene as a specific method for detection of Salmonella w...

Poultry has long been cited as a reservoir for Campylobacter spp., and litter has been implicated as a vehicle in their transmission. Chicks were raised on litter removed from a broiler house positive for Campylobacter jejuni. Litter was removed from the house on days 0, 3, and 9 after birds were removed for slaughter. Chicks were raised on these three litters under controlled conditions in flo...

Strains of Clostridium perfringens are a frequent cause of food-borne disease and gas gangrene and are also associated with necrotic enteritis in chickens. To detect and quantify the levels of C. perfringens in the chicken gastrointestinal tract, a quantitative real-time PCR assay utilizing a fluorogenic, hydrolysis-type probe was developed and utilized to assay material retrieved from the broi...

Abstract The aim of the current study was to examine mentoring relationship with closest grandparent, considering perceived grandparent’s perspective taking, and identity processes among Polish emerging adult grandchildren. A total 424 adults (41.3% male) aged 18–25 completed self-assessment measures. structural equation modeling analysis revealed positive associations between perception relati...

During the period from July 2002 to June 2003, infectious bursal disease (IBD) was suspected in 101 commercial flocks of broiler chickens on the basis of clinical and post mortem findings in some districts of the Haryana state, India. Bursal samples were collected randomly from 20 flocks for the detection of infectious bursal disease virus (IBDV) by reverse transcriptionpolymerase chain reactio...

The antimicrobial resistance of Klebsiella species in the poultry industry is becoming a public concern. In support our recent publication "Characterization of antimicrobial resistance in Klebsiella species isolated from chicken broilers" (Wu et al., 2016) [1], multilocus sequence typing (MLST) and gyrA PCR-RFLP assays were conducted to identify the genetic relationships between and phylogeneti...

Background: Fowl adenoviruses (FAdVs) are distributed widely throughout the world, and domestic avian species of all ages are susceptible. Fowl aviadenoviruses (FAdVs) can be separated into 5 different species (A-E) with various genotypes and 12 serotypes. Some geno- or serotypes induce hepatitis-hydropericardium syndrome (HPS), inclusion body hepatitis (IBH), and adenoviral gizzard erosion (AG...
