Probiotics which do not result in the development and spread of microbial resistance are among the candidate replacements for antibiotics previously used as growth promotors. In this study the effect of in-feed supplementation of the butyrate producing Butyricicoccus pullicaecorum strain 25-3T on performance, intestinal microbiota and prevention of necrotic enteritis (NE), a disease caused by C...

The present experiment investigated the impact of administrations lactic fermented turmeric, black pepper or a mixture both into diets on hematological parameters and intestinal ecology morphology broilers. Three hundred ninety two broilers were spread to T0 (control), T1 (feed administrated with 1% turmeric), T2 pepper) T3 turmeric pepper). Blood sampling was conducted at days 21 35, while day...

This study was carried out to evaluate the effects of Satureja khuzistanica essential oils (SKEO) on performance, serum metabolites and differential counts of white blood cells in broiler chickens. A total of 280 one-day-old straight-run Cobb 500 broiler chickens were allocated into seven treatment groups with four replicates of 10 birds each from day 1 to 42 of age. The birds were continuously...

Farmers of the poultry industry are seeking new and more efficient techniques to produce broilers quickly, without sacrificing quality, nutrition, or cost, as demand for rises in conjunction with human population. This study analyzed weight from day 1 harvest determine impact each daily weekly on final broilers. The experiment was conducted a conventional type housing. One hundred thousand male...

Broiler chicks were reared on either wet litter or dry litter to compare the development of footpad dermatitis (FPD). Broilers reared on wet litter first developed FPD at 14 days of age. Their FPD scores increased sharply after 21 days of age, reaching 2.92 at 42 days. In broilers reared on dry litter, FPD was first observed at 28 days of age, and the FPD score was only 0.70 at 42 days. When 21...

Avian Metapneumovirus (aMPV) affects both turkeys and chickens. The virus is associated with swollen head syndrome (SHS) in broilers. Most of the studies regarding aMPV have been done in turkeys. Not much is known about the pathogenesis and immune response to aMPV in broilers. Therefore, our objectives were to study the pathogenesis and immune responses of broilers experimentally infected with ...

An experiment was conducted to investigate the effect of phytase transgenic corn (PTC) on intestinal microflora, and the fate of transgenic DNA and protein in the digesta and tissues of broilers. A total of 160 1-day-old Arbor Acres commercial male broilers were randomly assigned to 20 cages (8 chicks per cage) with 10 cages (replicates) for each treatment. Birds were fed with a diet containing...

Chlamydia psittaci is prevalent in broiler chicken production. However, the role of C. psittaci in the respiratory disease complex needs to be clarified. Our aim was to identify the time point when a C. psittaci infection appeared on a broiler farm and to examine the presence of other respiratory pathogens at that time. We focused on the 'major' respiratory pathogens occurring in Belgian broile...

Three hundred one-day-old male broilers (Ross 308) were allocated to five treatments with four replicates in a completely randomized design. Treatments supplemented with 0 (control), 400, 800, 1200 or 1600 ppb chromium in the form of chromium chloride. All birds were intramuscularly immunized with killed vaccine of Newcastle and Avian Influenza (H9 N2) virus at 8 d. On days 18 and 28 blood samp...
