the present study was conducted to estimate correlations among performance and egg quality traits in iranian native fowl. data were collected from 21,679 birdsat the isfahan native fowl breeding center to derive genetic parameters for performance traits and egg quality traits were measured on eggs of 1,020 birds. genetic correlations of performance and egg quality traits were estimated with a b...

PURPOSE OF REVIEW Allergy to hen's egg is common in infancy and childhood. Oral food challenges are often required to diagnose egg allergy, because of the limitation in the diagnostic accuracy of skin test and specific IgE to egg white. New molecular diagnostic technologies have been recently introduced into allergological research. In this article, we will review the recent literature regardin...

OBJECTIVE To examine differences in body composition and smoking between mothers of spontaneous monozygotic and dizygotic twins, while taking into account maternal age, gravidity, and educational attainment. DESIGN Retrospective cohort study. SETTING The Netherlands Twin Register. PATIENT(S) Mothers of twins (n = 19,357) registered with the Netherlands Twin Register. Data were selected fr...

AIMS To investigate markers of risk status that can be easily monitored in resource-limited settings for the identification of children in need of early developmental intervention. METHODS Eighty-five children in Kilifi, Kenya, aged between 2 and 10 months at recruitment, were involved in a 10-month follow-up. Data on developmental outcome were collected through parental report using a locall...

CONTEXT : Food allergy plays a significant pathogenic role among children with atopic dermatitis (AD). OBJECTIVE : The aims of this study were to evaluate allergy to egg in these children and determine the egg specific immunoglobulin E (IgE) cutoff point. DESIGN AND SETTING : It was a cross-sectional study that took place at Immunology, Asthma and Allergy Research Institute from 2005 to 200...

We conducted a field study in an area of endemic malaria transmission in western Kenya to determine whether mosquitoes that feed on gametocyte-infected blood but do not become infected have reduced or enhanced fecundity in comparison to mosquitoes fed on uninfected blood. Fifteen paired membrane-feeding experiments were conducted in which two strains of Anopheles gambiae mosquitoes were simulta...

The subgroup J of ALV (ALV-J) has emerged as an important pathogen of meat-type chickens since1989. This virus is responsible for economic losses due to both mortality and depressed performance inchickens. So, the objective of this study is the detection of ALV-J in the albumen of commercial and nativefowl eggs using RT-PCR. Three hundred and seventy egg albumens were randomly selected from dif...

the best method of fish breeding is the isolation of pure lines having high-producing hybrids. the decline in heterosis (dih) resulted from inbreeding, maternal effects, general combining ability (gca) and specific combining ability (sca) on reproductive traits (e.g., egg production, number of hatched egg, and hatchability of pure lines and crosses) of tiger, green, and albino barbie hybrids we...

The general lack of experimental evidence for strong, positive effects of egg size on offspring phenotype has led to suggestions that avian egg size is a neutral trait. To better understand the functional significance of intra-specific variation in egg size as a determinant of offspring fitness within a life-history (sex-specific life-history strategies) and an environmental (poor rearing condi...
