Breeding Objectives and Desired-Gain Selection Index for Rayeni Cashmere Goat in Pasture System
The aim of this study was to define breeding goals and determine the suitable selection index in Rayeni cashmere goat using simulated data. To select animals for increased quantity of meat, milk and cashmere produced, body weight of the doe (BWD), milk weight (MW), cashmere weight (CW), weight of kids for sale (WK) and number of kids for sale per doe (NK) was used as selection criteria. Four se...
متن کاملThe 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 کاملGenetic and Phenotypic Parameters for Semen Characteristics and Their Relationship with Scrotal Circumference in Black Bengal Bucks
Black Bengal goat is the heritage and one of the potential genetic resources of Bangladesh. Genetic and phenotypic parameters for semen characteristics and their relationships with scrotal circumference in Black Bengal bucks were estimated in this experiment. Genetic parameters were estimated by residual maximum likelihood procedure, fitting an animal model ignoring maternal genetic or permanen...
متن کاملIntroduction to Indexes
The idea of a yardstick or selection index for measuring the net merit of breeding animals is probably almost as old as the art of animal breeding itself. In practice several or many traits influence an animal‟s practical value, although they do so in varying degrees. The information regarding different traits may vary widely, some coming from an animal‟s relatives and some from the animal‟s ow...
متن کاملIntegration of genomic information into sport horse breeding programs for optimization of accuracy of selection.
Reliable selection criteria are required for young riding horses to increase genetic gain by increasing accuracy of selection and decreasing generation intervals. In this study, selection strategies incorporating genomic breeding values (GEBVs) were evaluated. Relevant stages of selection in sport horse breeding programs were analyzed by applying selection index theory. Results in terms of accu...
