EFFECT OFBETAINE  LEVELS ON BROILER PERFORMANCE  UNDER CYCLIC HEAT STRESS
ABSTRACT: This study was carried out at the Research Poultry Farm, Faculty of Agriculture, Sohag University,Egypt. It was designed to study the effect of betaine supplementation on broilers performance under cyclic heat stress. A total number of 375 Ross, one day-old were equally divided into five groups (75 birds/group) with three replicates (25birds / replicat). In the first group, birds ... Read more

"Effect of 1-Day-Old Body Weight on Subsequent Performance, Behavior and Egg Quality Traits in Laying Hyline-White Hens Kept in Cages ".
One of the main goals of chicken breeders is to improve laying performance and therefore, reliable predictors are required. In this study, the effect of 1-day-old chicks body weight (BW) on the laying performance, behavior and egg quality traits of laying Hyline-white hens was examined from 20-40 weeks. A total of 180 chicks were separated into three categories based on ... Read more

Performance of two Real-Time RT-PCR assays for quantitation of hepatitis C virus RNA: evaluation on HCV genotypes 1-4.
ABSTRACT Accuracy for monitoring of the concentration of hepatitis C virus (HCV) RNA represents a major challenge throughout the management of patients with chronic hepatitis C. To investigate the genotype-independent efficiency and the accuracy of two real-time detection reverse transcription-polymerase chain reaction (RT-PCR) assays; the Cobas Ampliprep/Cobas TaqMan (CAP/CTM); and the Abbott RealTime HCV (ART), a total of 184 samples ...
