To establish a voluntary pseudorabies qualified herd, a producer must test all breeding animals over six months old plus a progeny equal to 20 percent of the breeding swine population of the herd. Progeny must be randomly selected from the oldest swine in the herd that are less than six months old, and all must achieve negative results using an official pseudorabies test listed in § 12:68:17:11. To maintain this status the producer must test annually as follows:

1. (1) Conduct an official pseudorabies serologic test of 80 percent of all swine six months of age and older;
2. (2) Conduct an official pseudorabies serologic test of a number of progeny equal to 20 percent of the breeding swine population of the herd. Progeny selected must be the oldest in the herd that are less than six months old;

3. (3) All swine tested must be randomly selected and, in the case of the adult swine, representative of all age groups on the premises.

   The required annual testing must be accomplished by testing 25 percent of the required breeding swine and progeny every 80 to 105 days and finding all swine tested to be negative or by testing 10 percent of the required breeding swine and progeny monthly and finding all swine tested to be negative.
