This study was conducted to assay the use of Saturejahortensis L. (savory) essential oil in the drinking water on broiler production and blood glucose, uric acid, creatinin and cholesterol. Four hundred and twenty day old broiler chickens (Ross 308) was used in a completely randomized design with 6 treatments and 5 replicate. Experimental treatments included: 1) control, 2) Tween (a solvent for...

Background: Ascites syndrome is currently a serious disease issue for the global chicken industry. Ascites syndrome is a metabolic disorder frequently found in fast growing broilers including abdominal distention and standing fluid collection in chicken abdomen. It is one of the most common nutrition metabolic disorders. Materials and Methods: In this study, the clinical diagnosis technology of...

More than 8.5 billion chickens are slaughtered for meat production in the United States every year. Raised in industrial production systems, these animals experience crowded indoor confinement, unnatural lighting regimes, poor air quality, stressful handling and transportation, and inadequate stunning and slaughter procedures. Because they are selectively bred for rapid growth, broiler chickens...

BACKGROUND: Increasing of oxygen consumption in fast-growing broiler chickens is associated with the more pronounced occurrence of right ventricular hypertrophy and ascites. While, rearing of susceptible chickens in dark condition could reduce the metabolic rate of birds and hence the incidence of ascites. OBJECTIVES: The present study was designed to investigate a comparative study on the inf...

abstract: subgroup j avian leukosis virus (alv-j) was isolated in the late 1980s from meat-type chickens in the united kingdom. alv-j with exception of some acute variants, cause myeloid leukosis in meat-type chickens with long incubation period.in this study while the status of avian leukosis virus subgroup j in six different strain of broiler grandparent flocks of iran evaluated, the evaluati...

colibacillosis caused by e.coli is one of the most common illnesses in commercial chickens and induce high financial losses in the poultry industry due to morbidity, mortality and antibiotic expenses because of overuses. e.coli can mostly cause disease as a secondary or opportunistic pathogen, while certain strains with specific virulence factors even as primary pathogen can cause colibacillosi...

clinical observations and gross pathological studies have been performed in field cases in order to determine the effect of cleavers (galium aparine) seeds upon the productive traits and the health of broiler chickens. a negative impact upon productive traits (feedconversion ratio, growth rates and equalization) has been observed. the results of our studies allowed assuming that the health of b...
