About Juventis
Using three pig breeds in a terminal crossbreeding system
The commercial pig producer must decide where to buy his breeding stock and what his replacement rate per year will be. The latter is
necessary in order to maintain the most efficient age structure in the herd. The F1 gilts benefit from the fact that they are hybrid and
as a rule outperform the average performance of the two pure breeds/genotypes, particularly with regard to maternal traits. The
introduction of a third pig breed (pure or composite) and thus a terminal sire line in this breeding programme enhances the further
exploitation of heterosis. This pig breeding plan is most commonly practiced in South Africa and probably worldwide. However from a
practical point of view the following aspects require consideration:
The need to budget well and accurately in order to receive and pay for the supply of replacement stock at regular intervals.
The introduction of breeding stock from outside increases the health risk in the pig herd and could also lead to additional problems.
Special attention should be paid to bio-security and health.
In essence the genetic supplier of pigs, provides the ingredients (F1- gilts/motherline semen and terminal semen), the management and
nutritional guidelines, protocols and back-up service, and the commercial pig producer follows the recipe to produce lean pork meat.

FOOTPRINT IN AGRICULTURE
Danie Visser Pr.Sci.Nat Danie Visser has obtained a BSc Agric & BSC Agric (Hons), Diploma in Farm Business Management, MBA, MSc Agric & Phd in Agricultural Economics ( Structuring of breeding objectives in the pork supply chain (PhD study) . Since 1985 he has been involved in almost all facets of agriculture, namely: from extension, training, research, involvement at universities and agricultural colleges, mentor ship, co-ordination of two national projects/schemes, business development, optimization studies, genetic evaluations in pig breeding, strategic and business plans, consultations, local and international networking, implementation of new technologies, computer programs, registration of trademarks, marketing, market surveys, to managing director of a large pig breeding company in SA. Danie has written more than 90 popular, short and scientific articles, made chapter contributions in seven books and manuals pertaining to Livestock Production and has written two books on Pig Production. His popular book, Modern Pig Production , was released during October 2014. It is a comprehensive handbook for the pig industry. Danie serves inter alia on SAPPO’s research committee, is involved in post graduate studies at the University of Pretoria and furthermore consults on pig breeding, business optimization, strategic management, supply chain management and real estate. Danie was a founder member of the pig breeders company - Alliance Genetics South Africa (Pty) Ltd, and is actively involved in scientific and practical pig breeding in South Africa. Through his involvement, quality breeding pigs were exported to pig breeders in Tanzania, Ghana, Angola, Zimbabwe, Zambia and The Seychelles during 2016/2017 and the 1st two pig exports to Nigeria in 2019. Focusing mainly on the Duroc , Landrace and Large White pig breeds (as well as F1 breeding animals) originating from South Africa.Soli Deo Gloria!
Pig breeding
inter alia
,
“ implies the application of genetic principles and methodology to extend the production capacity of animals.”
Principles of Genetic Improvement and Selection
Livestock
breeding
operations
usually
follow
the
classical
pyramid
structure
where
the
providers
of
parent
stock
occupy
the
apex
from
where
the
breeding
stock
flow
through
one
or
two
layers
of
multipliers.
Judicious
performance
testing
and
modern
genetic
evaluation
methods
will
optimize
genetic
progress
and
ensure
sustainable
genetic
progress
in
all
the
other
layers.
The
entrance
of
large
breeding
companies
has
not
changed
this
basic
structure
since
they
still
operate
their
line
development
and
the
crossing
of
maternal
and
terminal
lines
within
this
structure.
It
is
important
that
the
breeding
objectives
in
nucleus
herds
accurately
address
the
needs
(production
targets)
of
commercial
producers.
More
than
ever
in
the
history
of
pig
breeding
the
health
status
at
the
nucleus
herds
and
AI
stations
are
paramount.
The
concept
of
bio-
security
and
high
health
have
migrated
successfully
down
the
other
layers
of
the
breeding
pyramid
and
are
equally
important
and
manifested
inter alia
in high health compartments.
