avian intestinal spirochetosis (ais) is a disease of birdscharacterized by a marked colonization of the cecum and/or rectumwith anaerobic intestinal bacteria of the genus brachyspira. thepurpose of the study was to determine the occurrence of brachyspiraspp from avian sources in iran and to characterize selected isolates bybiochemical and molecular methods. out of 165 fecal samples obtained fro...

An experiment was conducted to increase the quality of rice bran by fermentation using Bacillus amyloliquefaciens and humic substances and its utilization as a feed ingredient for broiler chickens. The experiment was carried out in two steps. First, the fermentation process was done using a completely randomized design in factorial with 16 treatments: i) Dosage of B. amyloliquefaciens (2.10(8) ...

Broiler chickens aged 40 and 46-days-old from two neighboring flocks belonging to a commercial broiler complex, presenting facial edema, severe respiratory signs and 10% mortality were analyzed. Pneumonic lesions and opaque thoracic and abdominal air sacs with foamy exudate were seen at postmortem examination. Histopathology of lungs showed fibrinoheterophilic pneumonia in both cases. Small pin...

The presence of Salmonella in chickens is a problem because poultry meat is recognized as a source of human salmonellosis. Fermented feed has characteristics like a high number of lactobacilli and high concentration of lactic acid, which could make chickens less susceptible for infection with Salmonella. Fermented feed might therefore prevent the colonization of chickens with Salmonella. Two st...

The high incidence of deaths during transport for slaughter is associated with poor welfare and represents a considerable loss to the poultry industry. In the period from 2009 to 2014, all shipments of broiler chickens to poultry processing plants were monitored in the Czech Republic and the numbers of chickens transported and those dying as a result of their transport were recorded and analyse...

A total of 448 Ross 308 male broiler chickens were assigned to seven treatments with four replicates, each containing 16 chicks. The birds were reared from d 21 to 42 and effects of physical sizes (ad libitum by a basal commercial broiler diet with 3050 Kcal/Kg ME and 19.06% CP/Kg from 21 to 42 d. The chickens which received clinoptilolite (1.5% with particle size of 0.4-0.8 mm) showed a signif...

OBJECTIVE The objective of this experiment was to characterize the mRNA expression profile of type IIb sodium-inorganic phosphate cotransporter (NaPi-IIb) and the biochemical values of serum alkaline phosphatase (AKP), calcium, inorganic phosphorus, tibial ash and minerals of broiler chickens with aging. METHODS A total of 56 one-day-old Arbor Acres male broiler chickens were used. Broiler ch...
