Classify breeds of swine by their purposes & types; D. Explain pork production systems, production practices, and facility needs; E. Explain the importance of the swine industry and its contributions; and F. List important points to consider when selecting a swine breed and judge a class of market hogs.

Pork has changed in the last 20+ years… Today's pig yields a pork loin with: 77% less fat 53% fewer calories!

In the late 1970s Americans became aware of the link between fat in their diet and health. People began changing their diet: –Between 1979 and 1985, demand for pork fell 4 percent per year. –Sales of chicken surged. America’s change in diet revolutionized the pork industry

Science improves the pork you buy today. Since 1983, fat content of pork has been reduced 31%. Many pork cuts have less cholesterol than chicken.

How?????? Improved Feed Improved Environment Improved Genetics

Swine Terms Sow: female pig that has produced litters Gilt: young female pig which has not produced young Barrow: Male hog that has been castrated while quite young Boar: male hog of breeding age Objective A: Define terms relating to swine production

Weaner pig: young pig that no longer relies on the sow’s milk. Pure Bred: an animal carrying only one blood line. Mongrel: an animal of nondescript or mixed breeding Pedigree: a written record of an individual animal’s parentage and ancestry. Farrow: Process of a female pig giving birth Swine Terms Objective A: Define terms relating to swine production

Poland China Originated in the US Black with white snouts, legs and switch Generally poor mothers Drooped ears Swine Breeds Objective B: List common swine breeds and characteristics

Spots Developed in Indiana Black and white spots Drooped Ear Efficient feeders Noted for rapid weight gain Swine Breeds Objective B: List common swine breeds and characteristics

Yorkshire Originated in England White Large, erect ears Known as “The Mother Breed” Produces large litters Swine Breeds Objective B: List common swine breeds and characteristics

Lard Type- Known to carry a lot of fat example: Berkshire, Poland China, Bacon Type- Known to be long and have a deep side example:Tamworth, Yorkshire Meat Type- Produce a lot of meat in general example: All other breeds Swine Types Objective C: Classify Breeds of Swine by their purposes and types

Production systems: 1- Farrow to Finish: Pigs are farrowed and raised til ready to harvest all at the same facility. 2-Feeder Pig System- Farrows pigs and raises and sells after weaning. (about 40 lbs) 3- Finishing Feeder Pig System- Buys weaned pigs and raises til ready to harvest. 4- Purebred System: Goal is to produce high quality registered breeding stock for use by commercial facilities. -Least common Objective D: Explain pork production systems, production practices, and facility needs Swine Production Systems

Circle 4 Farms Milford, UT Farrow to Finish 12 th largest in the world. Circle Four markets 24,000 pigs each week. Most commercial pigs are raised in buildings such as this. These building are thermostatically controlled but do have windows with automatic curtains. Objective D: Explain pork production systems, production practices, and facility needs

General Swine Management: Fresh water Adequate feed (usually corn) Heat in winter or cooling in summer – Trivia: Why do pigs like the mud? Objective D: Explain pork production systems, production practices, and facility needs

Facts about Pigs!!! How much do newborn piglets weigh when they are born? – 3 to 5 pounds How much do pigs weigh when they go to market at 6 months old? – 250 pounds Objective D: Explain pork production systems, production practices, and facility needs

Piglets 1- Clip Needle Teeth 2- Castrate males 3- Notch ears: method of identifying pigs -Used instead of ear tags because pigs easily rub tags out Pig’s RIGHT= Litter number Pig’s LEFT= pig number Objective D: Explain pork production systems, production practices, and facility needs

Litter# =31Pig# 9+1=10 Litter# 81+1=82Litter# 27 Litter# 9 Pig# 9+1+1=11Pig# 9+3+1=13 Pig# 1+3=4 Objective D: Explain pork production systems, production practices, and facility needs

FACTS about PIGLETS… – Nurse (drink milk from the mother (sow) – Nurse every hour for the first three weeks – Need to be kept warm at 90 degrees (heat mat or heat lamp) Objective D: Explain pork production systems, production practices, and facility needs

Sows – Farrowing Crate Used to prevent sow from laying on piglets Objective D: Explain pork production systems, production practices, and facility needs

More Facts about about Sows… How long is the gestation period of a sow? –3 months, 3 weeks and 3 days –A sow has two litters per year (all her piglets are called a litter ) –Sows average 8 to 12 piglets in a litter Objective D: Explain pork production systems, production practices, and facility needs

Swine Contributions The average consumer in the U.S. eats fifty pounds of pork per year. Objective E: Explain the importance of the swine industry and its contributions to society

Byproducts from Pigs – Crayons – Chalk – Cement – Dye – Jello – Paint brushes – Plastic – Makeup – Matches – Antifreeze – Weedkillers – Dog Food – Linoleum Byproduct= A secondary or incidental product. NOT the original intention. Objective E: Explain the importance of the swine industry and its contributions to society

Medical Contributions Heart Valves Insulin Pigskin Research Objective E: Explain the importance of the swine industry and its contributions to society

Nutritional Facts about PORK… Protein Iron Zinc Vitamin B Thiamine Builds and repairs body tissues Helps with energy production Enhances and protects bones Ensures healthy nerve tissue Builds and repairs nerves and muscles Objective E: Explain the importance of the swine industry and its contributions to society

Pork and the Rural Economy Pork Industry consumes 10% of the total US corn crop billion bushels. Pork Industry consumes 27% of all soybean meal million bushels. Objective E: Explain the importance of the swine industry and its contributions to society

. Steps to Judging Swine 1.View animal from the ground up, then from the rear and work forward 2.Rank based on the traits of importance they possess Objective F: List important points to consider when selecting a swine breed and judge a class of market hogs

Ranking of Traits Market Hog 1. Degree of muscling 2. Growth 3. Capacity or volume 4. Degree of leanness 5. Structure and soundness Objective F: List important points to consider when selecting a swine breed and judge a class of market hogs

1- Degree of Muscling 1-Center width of Hams Objective F: List important points to consider when selecting a swine breed and judge a class of market hogs

1- Degree of Muscling 2- Width of Base Objective F: List important points to consider when selecting a swine breed and judge a class of market hogs

1- Degree of Muscling -Bad= very smooth over top and no shape to muscle -Good= Large pork chops on both sides of the backbone give the extreme “butterfly” shape 3- Shape Objective F: List important points to consider when selecting a swine breed and judge a class of market hogs

2- Growth Rule of thumb: Heaviest pig = fastest growing pig Lightest pig = slowest growing pig. Hogs sold by the pound Pigs need to grow at a high rate and reach market weight at an early age Objective F: List important points to consider when selecting a swine breed and judge a class of market hogs

3- Evaluating Capacity and Volume Width Depth Length (determined by body width, depth, and length) Objective F: List important points to consider when selecting a swine breed and judge a class of market hogs

4- Degree of Leanness Lean Fat Objective F: List important points to consider when selecting a swine breed and judge a class of market hogs

5-Evaluating Structure and Soundness Bad=Straight hock Bad= Swollen or “Puffy” hocks Well formed hock 1- Hock Objective F: List important points to consider when selecting a swine breed and judge a class of market hogs

5-Evaluating Structure and Soundness 5-Evaluating Structure and Soundness 2- rump Bad=Extremely Steep Good rump- allows for fluid movement Objective F: List important points to consider when selecting a swine breed and judge a class of market hogs

5-Evaluating Structure and Soundness 5-Evaluating Structure and Soundness 3-shoulders Bad= Too straight Good slope- ease in movement Overall: -Can the hog move easily? -Is it limping? Objective F: List important points to consider when selecting a swine breed and judge a class of market hogs
