| Abstract: |
| 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 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. Relative importance of BWD, MW, CW, WK and NK traits were -0.038, 0.899, 0.019, 0.005 and 0.019, respectively. Four selection indices were proposed (I1 – I4) to compare change of aggregate genotype value, genetic and economic gain for breeding goal and genetic gain for all traits included in indices based on selection index. Maximum of aggregate genotype value, genetic and economic gain was calculated for 0.04 buck ratio with the full selection index (I1). So, the most suitable selection index for this breed is index 1 which included BWD, MW, CW, WK and NK. |
