Temperatures before and after farrowing measured by using rectal thermometer, infrared camera and laser thermometer. Legend: Descriptive presentation of body temperature 48 h before to 24 h after farrowing measured by using rectal thermometer (RT, right axis), infrared camera (IRC, left axis) and infrared laser thermometer (IRT, left axis) in 91 sows in three Norwegian piglet producing farms. Time point zero (red vertical line) denotes the birth of the first piglet. The “lpoly” function used performs a kernel-weighted local polynomial univariate regression of the three temperature measurements on the y-axis and time at the x-axis
