Biotechnology

the science of altering genetic reproductive processes in animals; manipulating DNA of living organisms for commercial applications

Superovulation

Process which desirable cows produce many embryos 

USDA

organization that regulates meat and poultry products

FDA

organization that regulates all other domestic imported and animal drugs

EPA

organization that regulates pesticide use

Genetic engineering

Process of identifying, transferring a gene or genes for a specific trait from one organism to another

Bovine stomatotropin (bST)

Causes energy derived from feed to be used for milk production rather than weight gain; naturally produced in small amounts

Paylean

Common pig growth promotomer; orally active repartitioning agent

Straightbreeding

mating animals of the same breed

Crossbreeding

mating animals of different breeds

Purebred breeding

Type of straightbreeding; both parents are purebred with certain characteristics that belong to the breed in which they belong

Inbreeding

Type of straightbreeding; mating of related animals to increase genetic purity, done mostly for experiement

Closebreeding

Type of inbreeding; animals are very closely related, tracing back to more than one common ancestor

Linebreeding

Type of inbreeding; animals are distantly related with one common ancestor

Outcrossing

Type of straightbreeding; mating from different families of the same breed to promote the presence of desirable traits not present in the parents

Linecrossing

Type of outcrossing breeding; mating from two different lines of breeding within a breed

Grading up

Type of straightbreeding; mating of purebred sires to grade females to improve animal quality, improvement time depends on species; most improvement comes from first cross

Crossbreeding

Mating of two animals of different breeds to improve offspring traits; offspring will be hybrids

High

Traits with (high/low) degree of heritability show little improvement in cross breeding
