Table 4 Characteristics associated with the weight of pigs at 9 weeks of age (model 1)

From: An epidemiological investigation into the association between biomarkers and growth performance in nursery pigs

Variable Coefficienta SE 95% CI Pvalue
Weight at weaning 1.670 0.128 1.419, 1.920 <0.001
Age at weaning -0.226 0.069 -0.361, -0.090 0.001
Sex 0.524 0.424 -0.307, 1.356 0.217
Parity of sow 0.072 0.097 -0.117, 0.262 0.455
Stillbirths per litter 0.290 0.248 -0.197, 0.777 0.243
Live births per litter -0.102 0.093 -0.285, 0.081 0.274
  1. SE standard error, CI confidence interval.
  2. aThe predicted change in body weight (kg) at 9 weeks of age if the corresponding variable is increased by one unit (ie. the model predicts a decrease of 0.226 kg in body weight at 9 weeks of age if a pig is weaned one day later).
