Two hundred broiler chicken samples, 160 laying samples and 75 human stool were collected in Egypt. The microbiologically examined, the C. jejuni isolates confirmed biochemically by PCR targeting mapA gene of jejuni. prevalence cadF virulence was then determined using PCR. A total 17.33%, 17% 11.87% stool, respectively, positive for jejuni, with a 66 Campylobacter (15.17%). Ten (15.15%) carried...

this study was conducted to rank the broiler farms based on buildings, installations and equipment and its effect on production factors. to determine the contribution of each factor in ranking of farms, a multi-criteriadecision analysis (saw) was used. data of 108 broilers were recorded in specific forms and the amount of investment per broiler was calculated for individual factors. to calculat...

Problem statement: Acute heat stress at marketing age especially in broiler chickens raised in open houses with reduced means of heat exchange leads to economic losses. The objective of this study was to determine beneficial effects of early age thermal conditioning in reducing adverse effects of acute heat stress and decrease losses. Approach: Ninety one day-old broiler chicks were randomly as...

1. The aim of this experiment was to study the interactive effect of rearing temperature and dietary supplementation of arginine (Arg) or guanidinoacetic acid (GAA) on performance, gut morphology and ascites indices in broiler chickens raised under the same condition in the first 2 weeks and then reared under normal (23-26°C) or subnormal (17°C) ambient temperatures for the next 3 weeks. 2. Thi...

The aim of this study was to determine the presence of genes coding for alpha (cpalpha), beta (cpbeta), epsilon (epsilontx), iota (iotaA), enterotoxin (cpepsilon) and beta2 (cpbeta2) toxins in Clostridium perfringens isolates from broiler chickens and parent broiler breeder hens, using multiplex polymerase chain reaction (PCR) assay. The prevalence of C. perfringens in the intestinal segments a...

Recent trends occurring in broiler primary breeding companies are described. The structure and operation of broiler primary breeder companies are described from pedigree elite populations, through great-grandparent and grandparent generations, down to the parent stock. The relatively low value of fertility and hatchability, compared with yield and feed efficiency as selection traits, is assesse...

respiratory disease conditions are continuing to cause heavy economic losses in the poultry industry worldwide. ornithobacterium rhinotracheale (ort) has been incriminated as a possible additional causative agent in respiratory disease complex. although, ort has been proved to be highly sensitive to different chemical disinfectants, currently, ort infection appears to have become endemic and ca...

In this study, seroprevalence of avian reovirus (ARV) infections in broiler and broiler breeder chicken farms in Aydin, İzmir and Manisa provinces were investigated. Serum samples (n = 631) collected from 8 broiler breeder and 18 broiler flocks were tested for ARV antibodies using a commercially available ARV Enzyme Linked Immunosorbent Assay (ELISA) kit. The sampled flocks were not vaccinated ...
