At What Weight Should I Market My V
Feeder Pigs?

Answering this question will help the producers ol leeder pigs _ (
who {it into one of the Following production situations: (ll the
. producer who prefers to market shoats at a particular weight,
_ usually determined in part by the way the hog enterprise fits into _
the rest ol? his [arming operations: and (2) the producer who has  
greater llexibility in the hog enterprise and can adapt his planned
marketing weight l`or leeders to lit price opportttnities.

~ Hog-Corn Price Ratio May Alter the Picture 1 poss
It has been pointed out that there llf'?
1 1   ` hgures are averages for a 23-year peririrf. llllll
1   "   Individual years may, and did in sei- (ll lf
\     eral instances, differ widely from the _
1   '9 average pattern. One of the reasum lm?
1   for season-to-season changes in tlit um
1 price-weight relationship for feeders is HP1);
the influence of changes in the relative prohtability of feeding l. {CC0
1 corn to hogs. Often this prohtability is measured by the Img- ml"
1 corn price ratio. This ratio represents the number of buslids Hm
1 of corn required to equal in price 100 pounds of live hog. 'flit Ul U
relationship between weight and price of feeder pigs has lmii
measured by averaging the premium or discount in price pri _
100 pounds associated with a 10-pound increase in average weiglii _
for feeder pigs in the range between 4() and 160 pounds. J_
High hog-corn ratios usually mean price premium an lightweight!  
f\ only   lu general. when the hog-corn piiitt  
  °?¤l‘°°""i~~.,   ratio is favorable (for example: lfiilf

ir ligltt- i  W, 7, - _ \Vhen the hog»corn price ratio is
¤l>\1)'€1`S . 2°    unfavorable (for example: 8:1) the
T4 Hltttv `  heavier feeders tend to get price pre-
' ptllllltl I miums relative to lightweights. There
T   are two reasons for relatively higher
prices for heavy feeders when hog-corn price ratios are low. In
zttldition to the wish on the part of hog feeders to feed as little as
possible of the relatively high-priced corn to bring hogs to market
M thm weight, there is also the "two-way" market possibility for feeders, i l
_l)Cm(lv with lighter weight slaughter hogs—some in the heavier weights  
{ in M of l`eeders—going for slaughter during such periods.
mm thc The influence of the hog-corn price ratio upon the relation of
Tcimm weight to price of feeder pigs is of a rather broad nature, and does
in mc not follow closely on a month—to-month basis (Fig. 5). It is
Ccdmis apparent. however, that relatively higher prices for lightweight
Eeedm - feeders generally are paid during times when the hog-corn price
the IW ratio is higher than average, and relative price advantages in
bmlwh tttarketing the heavier weights of feeder pigs usually come in times
Og. rm ol unfavorable hog-corn price ratios.
