The purpose of this investigation was to study and compare the electrophoretic patterns of optic lensproteins of different species of domestic animals at pre- and post-natal ages. Optic lenses were removed from the embryo or adult sheep, cattle, goat, camel and chicken at the slaughter-house then homogenized and subjected to sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE). I...

The aim of the study was to investigate effect short-term dietary spirulina supplementation (1% and 3%) strain laying hens (White Leghorn: WL Rhode Island Red: RIR) on color, nutritional value, stability yolk. Egg weight not affected by any studied effects. Yolks from 3%-spirulina supplemented had higher retinol lower α-tocopherol content (p = 0.0001) when compared control. with 1%-spirulina ma...

the prevalence of methicillin resistant staphylococcus aureus (mrsa) and methicillin sensitivestaphylococcus aureus (mssa) carriage among poultry and poultry farmers in malaysia is largely unknown.in the current investigation, chickens and chicken farmers from 30 chicken farms were screened for mrsaand s. aureus carriage. the genetic characteristics of the isolates were determined through multi...

viral infections are the cause of great economic losses in the poultry industry. development of appropriate reagents and serological diagnostic kits will help to control these infections. the aim of this study is to prepare a peroxidase labeled anti-chicken igg using a mab (5b8) against chicken igg, for detection of chicken antibodies in elisa. hybridoma cells producing the mab 5b8 were culture...

The humerus is often used to assess skeletal health in laying hens. It usually contains an airsac in the central cavity, but studies have demonstrated that the humeri of some hens do contain medullary bone. This study used radiographs to compare the incidence of increased radiodensity in the central cavity of humeri between lines of highproducing non-commercial laying hens. Hens of six lines (n...

Estimating time-difference-of-arrival (TDOA) remains a challenging task when acoustic environments are reverberant and noisy. Blind channel identification approaches for TDOA estimation explicitly model multipath reflections and have been demonstrated to be effective in dealing with reverberation. Unfortunately, existing blind channel identification algorithms are sensitive to ambient noise. Th...

salmonella     species show different disease syndromes and host specificity, according to their antigenic profile. salmonella enterica serovar typhimurium is one of the most frequently isolated serovar from foodborne outbreaks. poultry meat has been identified as one of the principal foodborne sources of salmonella. in this study, the effect of microwave treatment of chicken meat samples wh...

nitroimidazole compounds have been traditionally used in the veterinary and human medicine, but their uses are sometimes associated with some side effects. toxicopathological effects of nitroimidazoles have always been a major concern. there is scant information available about the pathological alterations of nitroimidazole compounds in the embryo. the objective of this study was to determine t...

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, ...
