Emily House began her career as a geologist before an unlikely path led her into ruminant nutrition. After moving to New Zealand, she started working with two vets who wanted to shift from treating livestock disease reactively to preventing it, which meant looking closely at pasture as the major component of the diet.
Emily brings a background in earth science to her work interpreting pasture and soil analysis for animal health and performance. She was part of the team that developed the DietDecoder™, an online tool that assesses the mineral profile of pasture and flags risks to animal health before they show up as clinical problems.
In this episode, she explains why testing the mineral content of pasture goes further than the more familiar measures of dry matter, crude protein and energy that many farmers already use. She talks through real examples, from calcium and milk fever at calving, to copper deficiencies caused by excess sulphur and molybdenum in the soil, and how these mineral gaps can affect everything from hoof health to wool quality. We also discuss the range of responses available once a problem is identified, from targeted supplementation through to adjusting fertiliser regimes and building more mineral-dense pasture through species diversity, along with some striking parallels between what we're learning about animal nutrition and human health.
