by used this code

TITLE "bacillus";
PROC MIXED DATA=Bacteria2 PLOTS=PearsonPanel;
	class stallion Ejaculate  treatmeant;
	model bacillus = treatment;
	RANDOM stallion  stallion*Ejaculate stallion*treatmeant;
	LSMEANS treatment /adjust=Tukey;
RUN;

the problem in CA and Cw the mean is zero therfore the least Squares Means un readable as in picture

what is the least Squares Means her.

Best Regards.

I'm not sure what you mean by "unreadable." The bacillus variable is identically zero when Treatment='CA' or Treatment='CW'. The numbers being displayed for the LSmeans are tiny numbers on the order of machine roundoff. The numbers -227E-15 is scientific notation for -227 x 10^{-15}, which is -2.27 x 10^{-13}. Only the SW treatment has an LSMean that is significantly different from 0.
