Swine Segment Overview
Recent trends in the swine industryTrend application to livestock judgingUse of swine terminology in reasonsUse of swine performance data in
placings and in reasons
1986 Illinois State Fair Open Show Champion Barrow
Recent Trends in the Swine Industry
Early/mid 1990’s – 2004 emphasis on:– Larger framed– Leaner designed– Higher percent lean
$3,500 - 2002 National Barrow Show
Champion Spot Boar
2002 Fall ClassicReserve Champion Spot Boar
Freakish??
Prodigy Former $100,000 Sire
Lean Value Sires New Carlisle, Ohio
Trends in the Swine IndustryConsequences of the push for lean:
– sacrificed production traits especially growth and meat quality
– structural correctness problems developed
2004 Fall Classic Reserve Champion Spot Boar
Trends in the Swine IndustryLate 2004 selection focus switched to:
– Wider designed– Stouter boned– Bigger ribbed– Overall more productive animals
2004 Fall Classic Champion Spot Boar

Trends in the Swine Industry
How far is too far??
2007 National Barrow Show Hog College Duroc and Hampshire Boars and
Yorkshire Gilt
Trends in the Swine Industry
Consequences of the push for “body”:– Too high of condition level – fat is not body– Sacrificing percent lean– Compromising some breeding traits
When is the end of this trend and what is next??
2009 - Trend Leveling Out
Putting the “look”
back in??

Trend Application to Livestock Judging
Currently still a higher priority on width, mass, body and soundness
However - do not single trait select!!Complete animals still winFocus on incorporating trends more
into reasons sets than in the actual placing
Sound Like a “Hog Kid” - Incorporating Trend Terms
in ReasonsWider/narrower
chestedMore/less curvature
of ribMore/less center
bodyStouter/frailer
boned
More/less productive appearing
Sounder moving/more restricted in movement
Bigger/smaller footed
Sound Like a “Hog Kid” Regardless of the Trend
Market Animals– At least one appropriate carcass term -
percent lean, value based marketing system, backfat, loin eye area
– Not quarter, rib eye, quality grade, etc.Breeding Females
– Structure, underline, femininity– Not ham, muscularity, percent lean, etc.
Be specific!!

Scenario: Rank the gilts as they would be used in a purebred York total confinement operation. The breeder focuses on fast growing, sound gilts to make competitive hogs in the show ring and good mothers in the crate. This operation markets breeding stock to other purebred breeders and commercial producers. The offspring that are not structurally sound enough, or of breeding stock quality, are fed to 285 pounds and marketed on a lean grid.

Importance of the Scenario2006 National FFA Keep/Cull York Gilts
Purebred Yorkshire operation that markets showpigs and breeding stock. Remaining hogs are fed to 280 pounds and marketed on a lean grid. Raised on confinement and slats.
Priority on phenotype – especially soundnessUtilize MLI and Days EPD’s on paper
Keep/Cull York X GiltsGilts to be bred to Landrace boars for the production of replacement females. The gilt progeny sold to confinement facility and bred to terminal boars for the production of market hogs.
Priority on paper – Maternal Line IndexPhenotype – use to decide close pair and
confirm soundness
