Effect of High and Low Stocking Density on Age of Maturity, Egg Production, Egg Size Distribution in White and Brown Layer Hens: A Meta-analysis
Data of four layers flocks (#31-34) from North Carolina Layer Performance and Management Test of the Department of Agriculture and Consumer Services were used in the meta-analysis to find if an increase in space allowance can affect egg production traits in white and brown layers. Effects of space allowance of 310 and 413 cm2/bird on layers performance were compared in this study. The increase ...
متن کاملAchieving visual object constancy across plane rotation and depth rotation.
Visual object constancy is the ability to recognise an object from its image despite variation in the image when the object is viewed from different angles. I describe research which probes the human visual system's ability to achieve object constancy across plane rotation and depth rotation. I focus on the ecologically important case of recognising familiar objects, although the recognition of...
متن کاملPrediction of tolerance on the basis of quantification of egg white-specific IgE antibodies in children with egg allergy.
BACKGROUND It is thought that the natural evolution of food allergy has a good tolerance prognosis. However, there are few follow-up studies that determine the exact probability of tolerance to a given food or that analyze prognostic factors that can help us to understand the evolution of a child who begins life with a food allergy. OBJECTIVE We sought to determine the likelihood that childre...
متن کاملSkin prick test to egg white provides additional diagnostic utility to serum egg white-specific IgE antibody concentration in children.
BACKGROUND Levels of IgE antibody to egg white of greater than 7 kIU/L are highly predictive of clinical reactivity to egg, and lower levels often require evaluation with oral food challenge (OFC) to establish definitive diagnosis. OFCs have inherent risks, and diagnostic criteria indicating high likelihood of passing would be clinically useful. OBJECTIVE We sought to determine whether the si...
متن کاملStudy the Interaction of Ni Complex of Tetradentate Schiff Base Ligand with HEN Egg White Lysozyme
AbstractInteraction of Ni complex(Salen= N, N´-ethylene bis(salicylideneimine)) with hen egg-white lysozyme (HEWL) was studied by absorption spectroscopy, competitive binding study and thermal denaturation study. The protein binding affinity of Ni complex was found to be (3.0×103M−1). The binding plot obtained from the absorption titration data gives a binding constant of 2.4 (± 0.3)×103 M...
