During the course of the experiments the status of the birds (normal, sick, and dead) was recorded, and the serological status of each bird was determined at the start and at the end of the experiments.
Differential expression of MAP3K7IP1, HIPK2, BMP7, and MAP3K7 in the visceral peritoneum tissue, between the normal birds and the birds with HVP, was determined using a t-test with SAS 8.0 software (SAS Institute, Cary, NC, USA).
In our wild-caught group of birds those birds that developed elements of the somersaulting stereotypy performed similarly to the normal birds on the extinction task.

The activity of this enzyme was still twice as high as that of the normal birds at 16 weeks of age.
For 8 14 days, 10 25 birds died each day, compared with the normal number of 2 6 birds per day.
