The Effect of Dams of Sire Path Management on Genetic and Economic Parameters in a Simulated Genomic Selection Program
A deterministic model based on the gene flow method, considering the features of Iranian Holstein cattle population, was implemented in this study to evaluate the effect of altering the number of age-classes in the dams of future sire (DS) path and the number of dams required for breeding a young bull (YB), to be evaluated as future sire, on genetic gain and resultant economic efficiency of a g...
متن کاملGenomic selection for two traits in a maternal pig breeding scheme.
The objective of this study was to compare different implementations of genomic selection to a conventional maternal pig breeding scheme, when selection was based partly on production traits and partly on maternal traits. A nucleus pig breeding population with size and structure similar to Norwegian Landrace was simulated where equal weight was used for maternal and production traits. To genoty...
متن کاملTelemedicine: A systematic review of economic evaluations
Background: Telemedicine is an expanded term in health information technology that comprises procedures for transmitting medical information electronically to improve patients’ health status. The objective of this research is to evaluate the cost-effectiveness of telemedicine interventions in various specialty areas. Methods: The Cochrane Library and Centre for Review and Di...
متن کاملEconomic evaluation of genomic breeding programs.
The objective of this study was to compare a conventional dairy cattle breeding program characterized by a progeny testing scheme with different scenarios of genomic breeding programs. The ultimate economic evaluation criterion was discounted profit reflecting discounted returns minus discounted costs per cow in a balanced breeding goal of production and functionality. A deterministic approach ...
متن کاملDerivation of Henderson's Method of Incorporating Artificial Insemination Sire Evaluations into Intraherd Prediction of Breeding Values
A derivation is given for the method proposed by Henderson to incorporate evaluations of sires based on daughter records in other herds into the intraherd prediction of breeding values. The derivation consists of pretending the daughters in other herds have records which have been adjusted for the herd-year-season effects of their origin. These equations then are absorbed into the equation for ...
