ABSTRACT In the present study we used one hundred and twenty-five broiler chicks (Arbo) one- day old as experimental birds, were divided into five groups each of chicks. The first group kept control, 2nd was non-vaccinated challenged, 3rd infected with Emeria tenella at 15th days age 4th vaccinated 5th challenged. in 4 by locally prepared NE vaccine adjuvinated Aluminum hydroxide dose 0.5ml sub...

To study the anticoccidial and antioxidant effects of garlic powder (GP) and total sulfur amino acid (TSAA) on growth performance, faecal oocyst output, oxidative stress indicators and antioxidant status markers in broiler chickens, a 2 × 2 × 2 splitplot-factorial arrangement of treatments was used. A total of 480-day-old male broiler chickens were equally assigned to two plots. Two hundred for...

this study was conducted to evaluate the effect of ginger powder on the performance of salmonella challenged broiler chicks and to compare its efficacy as growth promoter with an antibiotic, avilamycin. in a completely randomized design, 300 chicks were divided into six groups, five replicates with 10 birds per each replicate. the treatments included negative control (basal diet without ginger ...

The development and use of recombinant vaccine vectors for the expression of poultry pathogens proteins is an active research field. The adeno-associated virus (AAV) is a replication-defective virus member of the family Parvoviridae that has been successfully used for gene delivery in humans and other species. In this experiment, an avian adeno-associated virus (AAAV) expressing the infectious ...

Breeding for disease resistance to Salmonella enteritidis (SE) could be an effective approach to control Salmonella in poultry. The candidate gene approach is a useful method to investigate genes that are involved in genetic resistance. In this study, 12 candidate genes that are involved in the pathogenesis of Salmonella infection were investigated using five different genetic groups of meat-ty...

Fowl adenovirus (FAdV) is the primary agent of inclusion body hepatitis (IBH) in poultry and caused serious economic impact due to high mortality poor productivity. To date, clinical cases IBH chickens increases over years Malaysia, thus, an effective local vaccine control disease outbreak dire need. The objective study was determine efficacy live attenuated FAdV serotype 8b isolate, UPM1137CEL...

Twenty-four pregnant cows were vaccinated intramuscularly with K99 extract from enterotoxigenic Escherichia coli and inactivated rotavirus as follows: six cows were injected with 2 ml of oil-adjuvanted vaccine; six cows were injected with 0.5 ml of oil-adjuvanted vaccine; six cows were injected with 4 ml of aluminum hydroxide-adjuvanted vaccine twice with a four-week interval; and six cows were...

Newcastle disease (ND) is a highly contagious infection of many avian species, mainly chickens and turkeys, with a devastating impact on worldwide poultry production. The ND accounts for heavy losses in Iranian poultry flocks. There are some reports regarding the epidemiology of this infection in Iran. This study was performed to investigate the infection of turkeys with a Newcastle disea...
