Table 1.

Mean (± SEM) genetic indices, bodyweights, and prior PPAI of the fertility groups. BV were generated from 2017 New Zealand Animal Evaluation Limited, incorporating data from a number of generations (Supplementary S1). ^*P < 0.05, ^**P < 0.01, ^***P < 0.001 compared with POS-CYC; ^#P < 0.05 compared with NEG-CYC. The difference between NEG-CYC and NEG-NONCYC for body condition score BV almost attained significance (P = 0.056)
