The term ``raising'' employed with reference to livestock in section
3(f) includes such operations as the breeding, fattening, feeding, and
general care of livestock. Thus, employees exclusively engaged in
feeding and fattening livestock in stock pens where the livestock
remains for a substantial period of time are engaged in the ``raising''
of livestock. The fact that the livestock is purchased to be fattened
and is not bred on the premises does not characterize the fattening as
something other than the ``raising'' of livestock. The feeding and care
of livestock does not necessarily or under all circumstances constitute
the ``raising'' of such livestock, however. It is clear, for example,
that animals are not being ``raised'' in the pens of stockyards or the
corrals of meat packing plants where they are confined for a period of a
few days while en route to slaughter or pending their sale or shipment.
Therefore, employees employed in these places in feeding and caring for
the constantly changing group of animals cannot reasonably be regarded
as ``raising'' livestock (NLRB v. Tovrea Packing Co., 111 F. 2d 626,
cert. denied 311 U.S. 668; Walling v. Friend, 156 F. 2d 429). Employees
of a cattle raisers' association engaged in the publication of a
magazine about cattle, the detection of cattle thefts, the location of
stolen cattle, and apprehension of cattle thieves are not employed in
raising livestock and are not engaged in agriculture.
