predict statement

Hi Asreml Users,

I am trying to use the predict statement to obtain predictions of the cow
(i.e. permanent environment) + animal genetic effects (I am interested in
the standard error of prediction of this sum).

The model and predict statements are as follows:

fyld ~ pfrn pjer agelin agequad,
 !r animal 0.7 cow 0.8 !f cgroup mv
predict cow 1:850 !ONLYUSE animal cow

However, the .pvs file has only zeros for the predicted value and the
associated standard errors:

 cow Predicted_Value Standard_Error Ecode
      7788125 *************** 0.0000 E
      7788133 0.0000 0.0000 E
      9171656 0.0000 0.0000 E
      9308154 0.0000 0.0000 E
      9467290 0.0000 0.0000 E
      9477086 0.0000 0.0000 E

Does anyone have any idea as to what is going wrong? Is it not possible to
obtain predictions of random effects?
