DNA information has the potential to generate value for each sector of the beef-cattle industry. The value distribution among sectors (breeding, commercial, feedlot, processing) will differ depending on marketing. The more descendants an animal produces, themore valuable each unit of genetic improvement becomes. Therefore, the value of using DNA testing to increase the accuracy of selection and...

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...

abstract the lack of water is the most important problem in extensive landscape especially turfgrass in arid and semi arid regions. the root responses in native and commercial grasses under drought stress were investigated. this experiment was in a factorial experiment based on unbalanced completely random design on the year 2006. the specious that we used in this experiment included (i) commer...

The aim of this study was to investigate genetic relationships between beef traits of station-tested young bulls and carcass and meat quality traits (MQ) of commercial intact males in Piemontese cattle. Phenotypes for daily gain (DG) and live fleshiness traits (width at withers: WW; shoulder muscularity: SM; loin width: LW; loin thickness: LT; thigh muscularity: TM; thigh profile: TP) and thinn...

The National Longitudinal Study of Adolescent Health data were used to test predictions from life history theory. We hypothesized that (1) in young adulthood an emerging life history strategy would exist as a common factor underlying many life history traits (e.g., health, relationship stability, economic success), (2) both environmental harshness and unpredictability would account for unique v...
