3.2 Phillip Strydom ARC Carcass Classi cation
The project  nally commenced on 3rd July when carcasses were selected on the slaughter line at the  rst abattoir (Eskort Heidelberg), brought to Irene and dissect- ed into meat, fat and bone. This process will be repeated at three more abattoirs (Fray’s at Cato Ridge) in Natal, (Winelands Pork, Cape Town) in Western Cape and (En- terprise Pork Packers, Olifantsfontein) in Gauteng
The Research Committee decided to investigate whether the prediction equation to predict car- cass lean content currently in use, as established by Bruwer (1992) is still su ciently accurate after 25 years. This is necessary because the average weight of carcasses increased substantially from 65 kg at the time when the original work was done to about 80 kg or more currently. Statistically it is bad practice to extrapolate regressions. The re- gression relies heavily on the back fat thickness to predict lean so that the prediction of lean in the modern genotypes with their low back fat mea- surements may be inaccurate. Classi cation and therefore remuneration of the producer as well as the price that processors have to pay, is based on lean content so that the importance of accuracy is self-evident. Furthermore the e ect of Improvac® castration on carcass classi cation needs to be es- tablished.
The University of the Free State (Prof Arno
Hugo) wanted to know whether taste panel work shouldn’t be done on the available carcasses to establish a link between palatability and classi ca- tion. The committee was of the opinion that this project must not be further complicated at this stage and that future work may be done on palat- ability.
The committee is of the opinion that communica- tion on research done by the industry to role-play- ers should be revised and that a communication strategy should be discussed during the planned brainstorming session. It is also necessary to devel- op a repository for easy access to all the research commissioned by SAPPO.
Concerns were raised on the state and availability of pig research facilities in the country and will also be discussed during the proposed brainstorming session. The availability of Baynes eld for research will be investigated.
SASAS Congress
SAPPO was invited by the South African Society for Animal Science to deliver a plenary paper on recent developments in the pig sector at their an- nual congress in September. Prof Francois Siebrits was asked to deliver the paper.
