Glossary


Agronomy – branch of agriculture dealing with crop production and soil management

AI – artificial insemination

All-in/all-out production – production system where animals are moved in and out of facilities in distinct groups to help reduce the spread of disease; facilities are normally cleaned and disinfected thoroughly between groups

Animal welfare – The American Veterinary Medical Association (AVMA) has defined animal welfare as “a human responsibility that encompasses all aspects of animal well-being, including proper housing, management, nutrition, disease prevention and treatment, responsible care, human handling, and, when necessary, humane euthanasia.”

Antibiotic – a chemical substance produced by a
microorganism that has the capacity to inhibit the growth of or to kill other microorganisms

Antimicrobial – an agent that kills bacteria or suppresses their multiplication or growth; includes antibiotics and synthetic agents

Aquifer – layer of permeable rock, sand, or gravel that contains or conducts groundwater

Backfat – amount of fat over a pig’s back; an indicator of the overall fat content of the animal; used in selecting breeding stock and in grading carcasses

Barrow – a male hog that has been castrated

Balanced diet – feed that has all the nutrients an animal needs to stay healthy and grow normally

Belly – lower side of a hog remaining after the loin and spareribs are removed; used to make bacon
 Biosecurity program – a program to help prevent diseases from being spread between herds; the program isolates animals, controls human traffic in and around the operation and includes facilities
sanitation

Boston butt – upper part of the pork shoulder

Breeding herd – includes boars and females in gestation, breeding and farrowing stages of production

Carcass – the two sides of the same processed animal

Case-ready – meat that is pre-priced and prepackaged by the processor for immediate display in the meatcase

Cold storage – the system whereby meat is stored under refrigeration or in the frozen state for a period of time to provide flexibility in the marketing of various products; not intended to take the heat out of products but rather maintain their previous cold state achieved before entering the facility; stocks of various products in cold storage may fluctuate during the year depending upon the supply and demand for that product. For instance, hams are collected in cold storage throughout the fall in anticipation of the huge demand for hams during the Christmas season.

Conservation plan – a combination of land uses and practices to protect and improve soil productivity and to prevent soil deterioration

Consumption – the total amount of a product consumed. Note: No direct measurement of meat consumption is available, so for pork and other meats, consumption is assumed to equal other disappearance since we know that the product was not exported or left in storage but do not know for sure how it was used.

Contract production – a business model in which one or more phases of the pig production enterprise is performed by a person or company (referred to as a “grower”) that does not own the pigs; growers provide land, buildings, labor, utilities and waste management services in return for a per pig or per pig space fee
