Since Log(0) is ILLEGAL, it will be replaced with a missing value.
If you mean that you have data values of 1 so that log(1) is zero,
these should not be treated as MIssing unless you have
!^0 !M0 or !^0 !D0
!M0 !^0 would do the operations arround the other way so that
original zeros become missing. The !M0 is redundant in this
case because ASREML should treat log(0) as a missing value anyway.

# ZERO is the number of zeros in the field (after transformation)
#MISS is the number of missing values (These will be dropped)
