The improvement in forage quality and quantity of summer-dry hill country pasture resulting from the introduction of clover is well recognised. However, ensuring the persistence of the commonly availablecultivars is challenging, in the face of seasonal moisture stress, intensive grazing, competition from established well-adapted pasture species, low soil fertility and low soil pH – conditions typical of the East Coast of the North Island. Here we quantify the value proposition associated with the introduction of white clover into a case study on a Gisborne sheep and beef farm, using a six-step process. A topographically explicit approach is taken, using an understanding of the underlying spatial variability, based on a combination of soil and pasture measurements, APSIM simulation modelling of pasture growth and farm system modelling of enterprise performance. We show that from a baseline of a typical low-fertility, diverse species hill country pasture, white clover introduction can increase spring and summer forage consumption by 17%, enabling inclusion of an additional 6-month bull finishing enterprise generating a 32% greater carcass weight production and leading to a 49% improvement in farm system EBIT. This represents a positive net present value of over $360,000 for the original investment in white clover establishment into existing pastures.

Translational medicine is the emerging scientific discipline of the last decade which will set the benchmark for the pharmaceutical industry research and development, integrates inputs from the basic sciences of computer modeling and laboratory research through the pre-clinical and clinical phases of human research to the assimilation of new therapies and treatments into everyday practice of patient care and prevention. With this brief insight authors tried in their humble way to summarize the underlying basis, the present and the potential future of this emerging view, to draw attention to some of the challenges and tasks it faces and to highlight some of the promising approaches, trends and model developments and applications.
