From: Strategic test-day recording regimes to estimate lactation yield in tropical dairy animals
The ‘average’ shape of simulated lactation curves using Wood’s model based on Pakistani Sahiwal data. One population of animals was simulated with an average peak and persistent tail (APHP; dashed line ---), which represented 4-year old animals. The other population had a higher peak and less persistent tail (HPLP; solid line ―) to simulate 9-year old animals.
