How to interpret Odds Ratio in Proc Glimmix with interaction

[LiHZ]

Hi everyone, 

Please bear with me. I'm confused to understand Odds Ratio in Proc Glimmix with interaction.

In Proc Logistic, if there is an interaction between factor A(two levels) and B(levels ≥2), Odds ratio of A will be presented in different level of B. In a word, there are different OR of A under different level of B.

However, in Proc Glimmix, only one OR is presented even if there is an interaction.

Here is my code are result.

proc glimmix data=mas ;
where farm ne 'hy';
class season(ref='summer') treatment parity(ref='1') result farm year ;
model result(event='pregnant')= season | parity | treatment /
dist=binary oddsratio ;
random farm year;
run;

As you can see, there is an interaction between treatment and parity or season.

However, OR of treatment is 1.509.

Why there is a difference between proc logistic and proc glimmix in the matter of OR?

Thanks in advance for the help!
