what is a market hog
What is a market hog?

A market hog can be any gender but the most common are gilts, sows, and barrows. We raise them for the intent of using them as food products and pork byproducts, such as, leather or the pig ears you give to your dog.

why do we judge market hogs
Why do we judge market hogs?

We judge or evaluate market hogs so we can ensure we get the most and best meat from the hog. This also means the producer will get the most money from his stock. It also helps in choosing a hog that will stay healthy. Undesirable characteristics may lead to soreness or lameness. This can cause the pig to go off feed. In turn, the pig would be costing the producer money.

Today’s Standards VS. Old Standards

Then…

Now…

Years ago, pigs were raised to be fat. People used the lard for various reasons so they made that part of the emphasis when they raised hogs.

In today’s culture, we want lean meats because they are healthier. So, we put most of the emphasis on lean meat from our pigs.

  • What do you look for in a replacement gilt?
  • Example Photos
what is a replacement gilt
What is a replacement gilt?

A gilt is a female swine before her first litter is born. Replacement gilts are raised for the purpose of reproducing good quality offspring and they will eventually replace a old sow.

why do we judge replacement gilts

We judge replacement gilts to ensure they pass desirable traits on to their offspring. Another reason for evaluating them is to ensure they will be able to produce and maintain a sizable litter. Finally, the main goal is ensure productive longevity.

emphasis

More emphasis is put on body structure and leg structure for replacement gilts. This is because they will be around much long than market hogs. The replacement gilts will be around for a few years compared to market hogs you are around for a few months. Try to think of it like this, in general, replacement gilts will be good for market but not every market hog will be good for breeding.

Review

Now We’ll judge a class!

The review will take you to a review page for a refresher on the basics of selecting a quality hog.

take a look at the market barrow class
Take a look at the market barrow class

After you’ve taken a look, continue on and answer a few questions on the placings.

slide64

CORRECT!

Hog 2 is the heaviest – muscled and nicest designed hog. He has a more correctly turned loin edge. He maintains the muscular thickness back into a powerfully constructed hip, ham, and stifle.

slide65

TRY AGAIN…

Hog 3 is nicely balanced; however, he lacks the overall muscle mass and volume found in the class

slide66

TRY AGAIN…

Hog 4 is a heavy barrow; however, is too non-descript in his muscle shape and design

slide67

TRY AGAIN…

Hog 1 is the most modest in muscle of any of the hogs.

slide69

CORRECT!

Hog 1 is the most modest in muscle.

slide70

TRY AGAIN…

Hog 3 is more conformationally correct hog of the pair. He is more descript over his loin edge. He is more free of fat throughout the lower third of his body.

slide71

TRY AGAIN…

Hog 4 is a heavier barrow

slide73

CORRECT!

Hog 3 is more conformationally correct hog of the pair. He is more descript over his loin edge. He is more free of fat throughout the lower third of his body. Hog 4 is a “pounds heavy” barrow; however, he gets too non-descript in his muscle shape.

slide74

TAKE ANOTHER LOOK…

Take another look at the muscle definition and at the condition.
