The livestock auction operations referred to in section 13(b)(13)
are those engaged in by the farmer ``as an adjunct'' to the raising of
livestock. This phrase limits the relative extent to which the farmer
may conduct livestock auctions and claim exemption under section
13(b)(13). To qualify under the exemption provision, the
auction operations should be an established part of the farmer's raising
of the livestock and subordinate to it. (Hearnsberger v. Gillespie, 435
F. 2d 926 (C.A. 8).) The auction operations should not be conducted on
so large a scale as to predominate over the raising of livestock. The
livestock auction should be adjunct to the farmer's raising of livestock
not only when he engages in it on his own account, but also when he
joins with other farmers to hold an auction.
