The present study and field measurements were carried out at broiler farms in Menoufia Governorate (Tala) during the period 2017 2018. great object of this was to determine effect some environmental factors (such as type strains, densities additions seasons effects) on production economical efficiency Government.The places these (Meet ElKeram, Kafer El Alawy, Bemam, Rabea.) - studied traits...

knowledge of the relation between agronomical traits with economical yield is very important in crop improvement and breeding. in order to study of genetic diversity and identifying yield components, 568 kabuli type germplasm and 390 desi type chickpea germplasm that were available in pulses collection of faculty of agriculture, university of tehran, was investigated in this research in 2009 in...

Body weight is an important economic trait in the selection of animals. The main purpose of animal breeding practices is to improve traits of economic value (Mendes et al., 2005). These traits have close association with explanatory variables such as age, breed and morphological characters. Body measurements have been used in animals to estimate body weight (Topal and Macit, 2004; Yakubu et al....

Quantitative genetic analyses of fish composition have been strongly biased towards lipid deposition, rather than protein deposition. This is partly at odds with desires of the modern aquaculture industry, to improve the efficiency of lean growth. Using a quantitative genetic approach, we examined the selection potential in both protein and lipid components of wet weight growth in rainbow trout...

abstract objective: globally, 3-5.2 percent of people suffer from diabetes which is one of the most serious metabolic disorders resulting in an increase in inflammatory biomarkers e.g. interleukin-6, tumor necrosis factor-alpha, and c-reactive protein. the aim of this study was to investigate the relationship between inflammation, oxidative stress and fasting blood glucose, lipid profile and an...

OBJECTIVE The growth, carcass and retail cut yield records on 1,428 Hanwoo steers obtained through progeny testing were analyzed in this study, and their heritability and genetic relationships among the traits were estimated using animal models. METHODS Two different models were compared in this study. Each model was fitted for different fixed class effects, date of slaughter for carcass trai...

First published May 3, 2005; 10.1152/physiolgenomics.00208.2003.— Obesity and Type II diabetes are complex diseases in the human population. The existence of a large number of contributing loci and gen...

The objective of the study was to estimate the genetic relationships between detailed reproductive traits derived from ultrasound examination of the reproductive tract and a range of performance traits in Holstein-Friesian dairy cows. The performance traits investigated included calving performance, milk production, somatic cell score (i.e., logarithm transformation of somatic cell count), carc...

Introduction: Human beings are inherently different and this fact can affect his/her behavior in work environments. The aim of this study was to examine the individual differences of employees (personality traits, biological and demographic factors) as a predictor of unsafe behaviors in a turbine manufacturing company. Material and Methods: In this cross-sectional study, safety behavior sampli...
