Comparing treatment feed vs. a control that had zero treatment intake

Did a hog feeding trial, where we had 5 groups; control & 4 trt groups.

Control group wasonly fed a basal diet of "Hog Chow" at 5% of its BW. These hogs also received "Hog Chow" in a separate pan at 2% of BW. Thus, basically received 7% of its BW in Hog Chow & not other feed. Thus, "treatment" intake for these hogs is "0.0"

 

Treatment groups were fed 5% hog chow and 2% of a treatment feed. Thus, they consumed a certain amount of treatment. See partial data below.

 

Goal: to compare "Chow intake",  "treatment intake", and "total intake" of each treatment group, to the control. Also, compare each trt group to each other (thus, all possible comparison).

However, the control trt intake (DMItrtg) is always 0.  How do I go about seeing if treatment diets are different than 0?

Don't think the following code is correct:

PROC MIXED;

CLASS TRT DAY ID;

MODEL DMItrtg = TRT|DAY / DDFM=KR SOLUTION;

REPEATED DAY/SUBJECT=ID TYPE = UN;

LSMEANS TRT|DAY/DIFF ADJUST=SIMULATE (REPORT SEED=121211) cl adjdfe=row  SLICE=(DAY TRT);

RUN;QUIT;

 

thanks
