1. Sub Program 2d Growth performance enhancement and Reproduction Mr. Rob Smits QAF Meat Industries

2. The Jigsaw of the Pork CRC Improvement of herd feed conversion efficiency More efficient performance from sow herd More efficient performance from progeny

3. Sub program 2d Commercial Objectives Improve the number of pigs weaned per sow mated. Identify and develop technologies that makes the mating process simpler and more successful. Improve the performance of progeny through management practices and nutrition.

4. Research Objectives Improved reproductive performance Sow longevity – management and nutrition to keep lean genotypes breeding longer. Investigate sow health to minimise mortality and improve fertility. Role of omega fatty acids in breeding gilts and sows to improve performance and longevity. Evaluation of protocols to synchronise oestrus and controlling time of ovulation to simplify AI

5. Research Objectives Advancing knowledge on reproductive physiology in sows Studying causes of embryo survival through early embryonic development, oocyte quality and inflammatory responses. Causes of foetal loss and termination of pregnancy. Nutritional/metabolic effects on oestrous resumption following weaning. Post-graduate training to continue excellence in reproductive physiology

6. Research Objectives Seasonal Infertility Remains an unsolved production constraint in Australia Research efforts to study seasonal infertility/heat stress will be renewed through the Pork CRC. Research will look into the mechanisms involved in seasonal infertility - heat stress, light regimens, other consistent seasonal factors on reproductive physiology in the sow. Workshop to direct R&D direction. Producer input will be valuable.

7. Research Objectives Improving growth performance of progeny Management strategies for gilt progeny. Omega fatty acid (and other functional lipid) supplementation during lactation and post-weaning to improve health and performance of young pigs. Optimise the ractopamine regime to increase lean tissue and decrease fat tissue deposition in finisher pigs, especially males.
