The variables considered are especially the BW, ADG, and T103 (time to reach MBW). The information includes the mean, SD, CV, and the minimum and maximum values for each variable.

*Corresponds to the last measurements with all pigs present in the finishing barn but 10 more days elapsed/passed, approximately, until pigs were sent to slaughter.

The time to reach market body weight (MBW) was estimated (not measured) from the Gompertz model.

Corresponds to the last measurement just before the first group of animals was sent to slaughter the next day.
