From: Strategic test-day recording regimes to estimate lactation yield in tropical dairy animals
Probability density plots of the mean square error of prediction from Wood model lactation estimates. The probability density plots are shown separately for random selections of test-day (TD) sampling regimes of 4, 5 and 6 TD per lactation; plot (a) shows the trend for the simulated lactations with an average peak and high persistency (APHP) and (b) for the simulated lactations with a high peak and low persistency (HPLP); the line type represents the number (m) of TD per lactation used to estimate the lactation yield, where dotted (•••) is for m = 4, solid (―) for m = 5 and dashed (−−−) for m = 6.
