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   85   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   latest   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.      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.
