Improvements in eating satisfaction will benefit consumers and should increase beef demand which is of interest to the beef industry. Tenderness, juiciness, and flavor are major determinants of the palatability of beef and are often used to reflect eating satisfaction. Carcass qualities are used as indicator traits for meat quality, with higher quality grade carcasses expected to relate to more...

AIM The experiment was carried out to evaluate different external and internal egg quality traits and to figure out their mode of inheritance from a set of hierarchically classified data. MATERIALS AND METHODS The data collected from 548 progenies (1 egg from each progeny) of 282 dams mated to 47 sires (1 sire mated to 6 dams) of a White Leghorn flock were used in the present study. Phenotypi...

In order to identify genes controlling meat quality and carcass traits we are aiming to combine two approaches: (1) the QTL analysis (2) and expression profiling. Here results of QTL analyses in different porcine resource populations and current attempts to identify functional candidate genes for meat quality traits are reviewed and own efforts are presented: A QTL scan for meat quality and car...

Meat quality traits are very important in the poultry industry. To identify single nucleotide polymorphisms (SNPs) and candidate genes affecting meat quality traits, a genome-wide association study was performed using the Illumina chicken 60K SNP beadchip in Jinghai yellow chicken. Four meat quality traits were measured. Two SNPs reached 5% Bonferroni genome-wide significance (P < 1.8E-6) and 7...

BACKGROUND Multiple types of chronobiological disturbances have been reported in bipolar disorder, including characteristics associated with general activity levels, sleep, and rhythmicity. Previous studies have focused on examining the individual relationships between affective state and chronobiological characteristics. The aim of this study was to conduct a variable cluster analysis in order...

The National Genetic Evaluation Program (NGEP), a project coordinated by the National Pork Producers Council (NPPC) with geneticists and commercial producers in America, provided good evidence for significant differences between terminal sire lines in progeny performance for production, carcase, meat and eating quality traits. The project identified “differences among sire lines for many muscle...

Plant traits are the key factors that determine herbivore foraging selection. The traits serving as defense traits against herbivores represent a wide range of traits, such as chemical, physiological, morphological and life-history traits. While many studies considered plant defense traits at the within-species scale, much less is known from comparisons of a wide range of closely related specie...

the objective of this research was to study the effects of phenological stages on yield and quality traits in 22 populations of tall wheatgrass agropyron elongatum. a split plot design was conducted using a complete randomized block with two replications in lorestan (borujerd), iran during 2007-2008. the genotypes were cut in five maturity stages as vegetation, stem elongation, heading date, an...
