IBP - One of the three largest beef-packing companies.
immunity - Ability of an animal to resist or overcome infection.
implant - To graft or insert material to intact tissues.
inbreeding - Mating of individuals more closely related than the average individuals in a population. Inbreeding increases homozygosity in the cattle population but does not change gene frequency.
income Difference between revenue and expenses that is referred to as net income; gross income refers to total income.
income statement - Financial statement that summarizes all revenues and expenses and used to determine the net income or net loss for a given period of time, usually a year.
independent culling level - Selection method whereby minimum acceptable phenotypic levels are assigned to several traits.
index - Overall merit rating of an animal.
inflation - General increase in prices that decreases the purchasing power of a dollar.
insemination - Deposition of semen in the female reproductive tract.
intake - The amount of feed consumed by an animal per day. Intake is usually expressed as a percent of bodyweight or in pounds per day.
integrated resource management (IRM) - Multidisciplinary approach to managing cattle more efficiently and profitably; management decisions are based on how all resources are affected.
integration - Bringing together of two or more segments of beef production and processing under one centrally organized unit.
intensive grazing management (IGM) - Grazing management where a grazing unit is subdivided into subunits (paddocks) with grazing periods typically less than 5 days.
intensive rotational grazing - Synonymous with “intensive grazing management.”
interest rate - Charge or fee associated with borrowed money.
intermuscular fat - Fat located between muscle systems. Also called seam fat.
intramuscular fat - Fat within the muscle or marbling.
inter se mating - Mating of animals within a defined population. Literally to mate among themselves.
intravenous - Within the vein. An intravenous injection is made into a vein.
in vitro - Outside the living body; in a test tube or artificial environment.
in vivo - Within the living body.
involution - Return of an organ to its normal size or condition after being enlarged (e.g., the uterus after parturition). A decline in size or activity of other tissues; the mammary gland tissues normally involute with advancing lactation.
ionophore - Antibiotic that enhances feed efficiency by changing microbial fermentation in the rumen.
IRM - See integrated resource management (IRM).
