Social Cognitive Career Theory (SCCT) explains academic performance as a function of conceptually distinct and interrelated cognitive variables. We aimed at extending SCCT?s performance model by examining the direct and ...

With the objective of mapping quantitative trait loci (QTLs) for performance and carcass traits, an F-2 chicken population was developed by crossing broiler and layer lines. A total of 2063 F-2 chicks in 21 full-sib families ...

Background and AimsDespite general agreement regarding the adaptive importance of plasticity, evidence for the role of environmental resource availability in plants is scarce. In arid and semi-arid environments, the ...

Reproductive performance is one of the most important factors for the productive efficiency in beef cattle production. Biometric testicular and physical and morphological traits of the ejaculate are used to evaluate the ...
