Commercial chickens in Jordan suffer from respiratory disease of undetermined etiology. This study was designed to document the involvement of Mycoplasma gallisepticum (MG) in this respiratory disease. Seventy six different chicken flocks with respiratory symptoms (48 broiler flocks, 21 layer flocks and 7 broiler-breeder flocks) were examined serologically by commercial MG ELISA kit and bacteri...

aflatoxins are fungal metabolites by strains of aspergillus (a.parasiticus and a.flavus) are produced. the clinical signs of aflatoxin poisoning include surgery autopsy, histological lesions and also create effects on the production of poultry flocks in experimental and natural occurrence have been reported in broiler chickens worldwide. the main signs of aflatoxin poisoning, loss of appetite, ...

In this study, the authors examined the technical performance of culture methodology using specific media: Mycoplasma isolation media of pleuropneumonia-like organisms (PPLO) broth and PPLO agar. Digitonin sensitivity, growth inhibition, the serum plate agglutination test, a commercially available enzyme-linked immunosorbent assay (ELISA) and a commercially available simplex polymerase chain re...

As activity levels of intensively managed broiler chicken vary over time, detailed knowledge on their influence is potentially useful to further adjust welfare assessment schemes. Therefore, this study investigated the influence of daytime and age on the performance of broiler chicken in two applied fear tests. On-farm studies were carried out in 14 flocks of intensively managed broiler chicken...

this experiment was conducted to investigate the effects of lactobacillus acidophilus on performance, carcass characteristics, blood parameters, and intestinal microflora of broiler chicks. the dietary treatments were: basal diet as control 1; basal diet plus 1g. kg-1 of a commercial probiotic bioplus2; basal diet plus 10 and 20 g kg-1 fermented milk that contained 2×108 cfu g-1 lactobacillus a...

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...
