^{1}CW = conventional weaning (n = 50), IS = intermittent suckling (n = 50), ISCo = intermittent suckling with comingling (n = 50)

^{2}Results obtained by scan sampling observations. Data were tested nonparametrically

^{3}Day = day in relation to weaning with weaning = d 0, d −25 is the day on which most the litters were born

^{ac}For each day, means with different superscripts are different (P < 0.05), indicating differences between treatments per day

^{xz}For each day treatment, means with different superscripts (P <0.05), indicating differences between days within each treatment
