the aim of this study was to assess the effects of exogenous histamine and h1 and h2 central receptorson electrocardiographic (ecg) parameters, heart rate and mean electrical axis in broiler chickens. for thispurpose, ross broiler chickens (750-800 g weight) received intracerebroventricularly (icv) histamine.moreover, to determine the receptors involved in histamine-induced alterations in ecg c...

this study was conducted because of influence of prebiotics (alphamune) and symbiotic (biomin) on histometrical development of small intestine and lymphatic tissue of caecal tonsil have been not reported on broiler chicken. in this study, different parts of small intestine and caecal tonsil, which is a major area of gut associated lymphatic tissue (galt) in chicken were selected. one hundred an...

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...

The effects of selected herbal dietary supplements on the growth performance and carcass quality of broiler chicken were investigated. Three hundred and eight day-old, male broiler chicks of Indian River strain were randomly allotted to seven experimental diets namely negative control, 0.0125% flavomycin (positive control), 0.1% Moringa leaf powder (MLP), 0.05% Moringa leaf powder, 0.035% Zigbi...

We conducted a survey in broiler farms from Romania to establish prevalence and distribution of Eimeria species using single PCR assay. We found Eimeria spp. in 21 (91%) out of 23 flocks, and in 11 (92%) out of 12 farms. Four species of Eimeria were identified: E. acervulina (21/23; 91%), E. tenella (14/23; 61%), E. maxima (5/23; 22%) and E. praecox (3/23; 13%). Infection with a single species ...

Continuous genetic selection and improvement in nutrition have led to a very fast growth rate in modern strains of broiler chickens. Metabolic disorders such as ascits, sudden death syndrome and leg problems are related to a rapid early growth rate in poultry, especially in broilers, and their incidence can be decreased by slowing early growth. The use of management tools to reduce metabolic di...

This study was aimed to evaluate the effects of substitution oregano essential oil (OEO) for antibiotics in plateau-broiler diet. Partridge Shank chicken is a broiler breed which has str...

The purpose of this study was to investigate the distribution of Salmonella species in an integrated broiler supply chain in Korea. A total of 1,214 samples from various steps of an integrated broiler production company including broiler breeder farms, broiler farms, broiler trucks, slaughterhouse, and retail chicken meats were collected and investigated. Salmonella was detected in 195 of the s...

Workers are exposed to dust in broiler chicken production during daily work activities. Poultry dust may contain inflammatory agents (e.g., endotoxin) and inhalation exposure has been associated with pulmonary symptoms. Current practice to reduce worker exposure to poultry dust is the use of respiratory protection (e.g., elastomeric face-piece respirator with a P100 and ammonia chemical cartrid...
