Figure 2 : Effect of maximum temperature (HT) on probabilities of sows in different parity groups1,2 having stillborn piglets (A) and on the number of stillborn piglets (B), from June to September.

1The regression coefficients of the HT term for sows in parity 3 or higher differed from zero (P<0.05). 2The regression coefficient of the HT term for sows in parities 1 and 2 did not differ from zero (P=0.73). The dotted lines represent the 95% confidence intervals for predicted means.
