Wild Boar
These wild hogs are still found in parts of the United States. Pigs used in modern pork production are thought to be descendants of the European wild boar. Wild boars are considered to be descendants of European wild boars introduced into the US for sport hunting, or the hybrid offspring of escaped domestic hogs.

Weaning
The process of removing the pigs from the sow and moving them to the nursery.

Tunnel Ventilation
A type of ventilation system where air enters at one end and is exhausted by ventilation fans on the other.

Ventilation
Process of providing fresh air for the animals and removing stale air and moisture along with dilution of noxious gases, particulates, etc. in the room.

Sow
After a female has borne a litter she is called a sow.

Slotted Floors
A type of flooring developed in the late 1950's. Narrow open slots in the floor allow manure and water to drain, keeping the floor dry and clean. Slotted floors for larger swine are normally constructed of concrete, but is normally plastic, wire or plastic covered wire for smaller animals. The manure that falls through the slots is collected in a gutter or pit and removed from the building periodically.

Shoat

Service
Breeding, the deposition of boar semen into the female. Breeding may be by done naturally by a boar or artificially by the manager, using semen obtained from a local boar or purchased from a supplier. Producers often use artificial insemination as a way to bring new genetics into their herd, without the biosecurity concerns involved with bringing new animals onto their farm.

Pen
Most swine are grouped together in pens, whether kept in a shelter or in a fenced open lot. The number of animals penned together may be less than 10 to several hundred, but is normally between 15 and 30.

Non-Productive Sow Days
Days a sow is neither lactating or gestating.

Mating
Breeding a sow or gilt after the onset of estrus and before ovulation, may include at least two services by different boars to ensure successful mating.

Market Weight
240 to 260 lbs.

Litter
The pigs that are born at one time to one sow

Limit Feeding
Feeding strategy in which pigs are fed a specific amount of food in a specific time period Vs free access to feed. Limit feeding is common in Europe, but normally only used for gestation animals in the U.S.

Legume
Any of thousands of plant species that have seed pods that split along both sides when ripe. Some of the more common legumes used for human consumption are beans, lentils, peanuts, peas, and soybeans. Others, such as clover and alfalfa, are used as animal feed. Legumes have a unique ability to obtain much or all of their nitrogen requirements from symbiotic nitrogen fixation.

Hand Mating
An individual female that is ready to be bred is exposed to an individual boar in a small pen for a few minutes, under the supervision of the producer.

Heat
Refers to the estrous period for the sow. The first estrous normally occurs 3 to 5 days after the pigs are weaned.

Finisher Pig
Production phase between the nursery and market.

Finishing Operation
The operation purchases feeder pigs from a feeder pig operation and feeds them to market weight at 240 to 260 lbs. Historically, producers purchased feeder pigs at auctions, but because of disease transmission concerns, most operations now bypass auctions and buy all of their animals from the same supplier.

Farrowing
The period from birth to weaning.

Feeder Pig Operation
Breeder sells pigs out of the nursery phase to a finishing operation to grow them out to market weight.

Corn Belt
The area of the United States where corn is a principal cash crop, including Iowa, Indiana, most of Illinois, and parts of Kansas, Missouri, Nebraska, South Dakota, Minnesota, Ohio, and Wisconsin.

Cooling
Cooling systems normally involve evaporating water to lower the temperature of the pigs. Generally used only for the breeding-gestation herd. Cooling also takes place by air movement in hot weather.

Diseases can be easily spread between herds and a strict isolation and sanitation program is normally practiced.

All-in, All-out production
A production system whereby animals are moved into and out of facilities in distinct groups. By preventing the commingling of groups, the hope is to reduce the spread of disease. Facilities are normally cleaned and disinfected thoroughly between groups of animals
