Intensive Red Meat Production (IRMP)
This unit combines the activities of the Beef Cattle Nutrition group (one scientist, one technician and 7 support staff) with one researcher and one technician from the Meat Production and Carcass Evaluation group.
The following people make up the IRMP group:
Dr Phillip E Strydom (Researcher: Meat Science)
Mr Moses Ratsaka (Researcher: Beef cattle nutrition)
Mr Klaas-Jan Leeuw (Researcher: Beef cattle nutrition)
Support staff complement: 7 people
This group does research, technology development and technology transfer to improve the efficiency, quality and safety of red meat produced in Southern African feedlots. We have a modern research feedlot with 48 pens, each holding ten animals. We also have 105 individual stanchions for data collection on individual animals. Our Meat Industry Centre is equipped with a D15 experimental abattoir that facilitates specialised research techniques or procedures that could otherwise not be performed in normal commercial abattoirs and provides a controlled environment for researchers to standardise procedures. Our program is run by dedicated, well-trained and experienced scientists, technicians and support personnel, backed by competent meat processing, analytical and microbiological laboratories. Furthermore, we present short courses and do least cost diet formulations, diet evaluations, feasibility studies and business planning.
We do client specific research where we are able to measure performance parameters such as growth, feed intake, carcass weight and carcass classification, from these we determine feed conversion and carcass characteristics. A Rand value can be placed on these parameters and the products like feed additives or medicinal treatments tested can be evaluated in terms of economic benefit below or above a set standard. A recent tested feed additive improved dressing % by more than 2 %, resulting in a higher carcass yield and income for the producer. Meat quality and consumer safety issues are addressed by the group, and taste panel evaluations are done to ensure consumer acceptability.
Animal experiments and meat quality evaluations are done on a client specific base and the execution of these experiments in terms of cost need to be negotiated.
The well attended feedlot course, which had more than 400 participants was cancelled. However, the course did result in a book which is now available at our library bookshop.
Diet formulation will cost R 300.00 per diet, and consultations will cost from R 300.00 depending on the amount of time spend.
