PIGBLUP*

PIGBLUP, a comprehensive genetic evaluation computer package / programme (to aid the breeder in his decision making process) was developed during the late 1980’s by scientists of the Animal Genetics and Breeding Unit at the University of New England, Armidale, New South Wales in Australia.
The power of PIGBLUP is based particularly on using information from all measurements and all relatives, as will as other animals in the breeding herd simultaneously.

The more records, the more information and as decisions are based on information, the better the information, the better the information the better the decisions will be.

PIGBLUP, thus is a tool to calculate Estimated Breeding Values. It divides phenotypic performance into:

Genetic effects
Environmental effects and
Other effects, thus calculating trends

EBV is the genetic value of an animal as a parent. PIGBULP combines the EBV’s into a single Rand Value Index.

PIGBLUP is a within herd genetic evaluation programme.
PIGBLUP furthermore uses information on correlated traits.
PIGBLUP was implemented in the South African pig stud industry during 1993/94. Almost all participating Scheme
members are receiving PIGBLUP profiles and their EBV lists – as frequently as requested.
