Trends in the Swine Industry Consequences of the push for lean:
– sacrificed production traits especially growth and meat quality
– structural correctness problems developed

Trends in the Swine Industry Late 2004 selection focus switched to:
– Wider designed – Stouter boned – Bigger ribbed – Overall more productive animals

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??

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 win Focus on incorporating trends more
into reasons sets than in the actual placing
![Page 19: National FFA Convention Livestock Coaches Clinic · National FFA Convention Livestock Coaches Clinic Swine Segment Tammy Miller Joliet Junior College . October 25, 2012 . Swine Segment](https://reader030.vdocuments.us/reader030/viewer/2022041006/5eac87a76ade9400560c25b5/html5/thumbnails/19.jpg)
Sound Like a “Hog Kid” - Incorporating Trend Terms
in Reasons Wider/narrower
chested More/less curvature
of rib More/less center
body Stouter/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.

Swine Performance Data Importance of the Scenario 2006 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 soundness Utilize MLI and Days EPD’s on paper
![Page 24: National FFA Convention Livestock Coaches Clinic · National FFA Convention Livestock Coaches Clinic Swine Segment Tammy Miller Joliet Junior College . October 25, 2012 . Swine Segment](https://reader030.vdocuments.us/reader030/viewer/2022041006/5eac87a76ade9400560c25b5/html5/thumbnails/24.jpg)
Keep/Cull York X Gilts Gilts 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 Index Phenotype – use to decide close pair and
confirm soundness
