Many of the poultry flocks produced in the United Kingdom are colonized with Campylobacter, and the intensive nature of poultry processing usually results in contaminated carcasses. In this study, a previously reported molecular oligonucleotide probe method was used to track a specific flock-colonizing strain(s) on broiler carcasses during processing in two United Kingdom commercial poultry pro...
Background: Inclusion body hepatitis (IBH) caused by Fowl adeno virus (FAdV), is a re-emerging threat to broilers causing considerable economic loss poultry industry worldwide. Methods: The present study investigated the IBH outbreaks in commercial broiler flocks from different regions of India between 2019- and 2021 identified serotypes associated with it molecular characterization hexon gene ...
Three experiments were conducted with broiler chicks that were divergently selected for low or high incidence of tibial dyschondroplasia (LTD and HTD, respectively) to determine if the expression of intestinal calbindin-28 kD mRNA and protein differed between the 2 strains. In addition, levels of intestinal vitamin D receptor mRNA and plasma thyroid hormone concentrations were also examined. In...
Infectious Laryngotrachitis (ILT) is an acute respiratory disease with high morbidity and low mortality in poultry. ILT is caused by Gallid herpesvirus 1 (GaHV-1), a member of the Iltovirus genus and family Herpesviridae. It resulted in notable economic losses due to decreasing the growth rates, egg production, and increasing the mortality in commercial poultry, especially layer flocks, and usu...
The objective of this study was to assess the hatch window, hatchability and quality broilers` chick obtained from different breeder strains in a commercial hatchery. A total 57 600 hatching eggs (28 800 per strain) were collected flocks Cobb 500 Ross 308 broiler parent stocks at 60-61 weeks age. Each strain randomly coded as B strain. mean value eggshell temperature found be higher Strain (101...
Antimicrobial agents are used extremely in order to reducing the enormous losses caused by Escherichia coli infections (colibacillosis) in Iran poultry industry. In this investigation fifty avian pathogenic Escherichia coli (APEC) strains isolated from broiler chickens with colisepticemia and examined for susceptibility to antimicrobials of veterinary and human significance. In vitro antibiotic...
Background: Avian infectious bronchitis (IB) is a highly contagious viral disease which affects the poultry industry. The virus exists in a wide variety of genotypes, and phylogenetic analysis has been used to classify infectious bronchitis virus (IBV) strains. Aims: The object of the study is a molecular characterization of circulating IBV in Afghanistan as a ...
