Modelling and prediction of dairy sheep lactation curve using non-linear mixed effects model

Description

Test-day record of the ewes each test-day record covered milk yield (MY) and lactation parameters as total milk yield (TMY), days in milk (DIM), first test day records (FTD), test day records (TDR), peak yield (PY) and time of peak yield (TPY)

Steps to reproduce

Milk yield was recorded once a week throughout the full lactation period using a mechanical milking system at CEPIPSA. Trained personnel collected and documented test-day records, which were later compiled into a database containing reproductive and management variables related to each ewe.
