Influence of length of time system operational on farm There was a marginally statistically significant effect of Cumulative batch number within system on PRE-processing LBM% (F 1,73 =5.29, P = 0.024), but not POST-processing LBM% (F 1,74 =0.01, P = 0.940).
Whilst Farm 2 had lower average parity than Farms 1 and 3, this was marginally insignificant (Farm 1, system A = 3.12 ± SE 0.12; Farm 2, system B = 2.48 ± SE 0.21; Farm 3, system C = 2.96 ± SE 0.24 and system D 2.93 ± SE0.11, F 3,115 =2.31, P = 0.080, from LMM).
