How do I make a contrast in repeated measures data?

[aska_ujita]

Hello there, 

Is there someone that knows how to do contrast analyze in repeated measures?

I have a data with three treatments in cattle: the first group is a control, the second group got a habituation protocol and third group got another different habituation protocol. So I would like to test the control (first) vs habituated (second + third group); and test between the habituated ones (second vs third). The traits were collected in day 0 (no habituation in any groups) and day 14 (14 days after end of habituation of the second and third group) and day 28 (28 days after end of habituation of the second and third group). So I have 3 repeated measures.

Is it possible to use the proc Mixed?

proc mixed data=B; /*behaviour*/
class group breed animal day;
MODEL VAR=GROUP DAY BREED GROUP*DAY;
repeated DAY / type= ANTE(1) subject=animal*group;
random breed / subject=animal;
lsmeans group*day / pdiff;
lsmeans group / pdiff;
lsmeans day / pdiff;

run;

Thank you!!
