From: Impact of litter size on sow stayability in Swedish commercial piglet producing herds

Fig. 1

Predicted stayability and litter size in first parity. Predicted probability (with 95 % CI) of a sow producing ≥4 litters in her lifetime (y-axis) versus the total number of piglets born in her first parity litter (x-axis). Predictions are from multivariable logistic regression including number of piglets, birth year of the sow, age at first farrowing and season at first farrowing as explanatory variables and herd included as a random variable. Data were selected from January 1 1997 to December 31 2009 from 24 Swedish piglet producing herds and included 38,346 observations
