Fig. 6
Example of feed intake, visit duration and number of daily visits for two pigs (a–c versus d–f). These examples are the same animals as shown in Fig. 5, and were selected based on body weight deviations, where the upper pig showed little deviations in observed versus expected body weight, whereas the lower pig showed many deviations in observed versus expected body weight. Red lines indicates the regression line from linear modeling. a and d Evolution of feed intake (kg/d) versus age (d). Based on the linear regression, lnMSEFI was quantified. b and e Evolution of visit duration (s/d) versus age in d. Based on the linear regression, lnMSEdur was quantified. c and f Evolution of number of daily visits to feeder versus age (d). Based on the linear regression, lnMSEn_visit was quantified
