An experimental study on the efficiency of a reduced selection index for production traits when the selection objective also considers reproductive traits



An experimental study on the efficiency of a reduced selection index for production traits when the selection objective also considers reproductive traits



ITEA 22(1): 75-77



Fowls were selected over 5 generations for body weight at 21 and 31 days of age and for egg mass between 28 and 30 days (full index, group 1) or for body weight at 21 and 31 days only (partial index, group 2). The response to the selection objective was significantly greater for fowls in group 1 than for those in group 2 (2.24+or-0.12 vs. 1.16+or-0.08, representing a reduction of 0.52 in selection index efficiency).
