Ketosis is a metabolic challenge that can occur for a number of reasons. Ian Sawyer lead a detailed discussion on these metabolic changes that occur over the transition period, how ketosis can be an outcome and how to mitigate ketosis. Ian dived into the factors that can influence dry matter intake post calving can come from either satiety (hunger) or hepatic oxidation theory (HOT). “The goal is to maximise the amount of glucose produced or spared per unit of ATP generated in the liver over time”. By doing so insulin can increase, NEFA rates decrease, DMI is increased and ketosis can be limited.
From testing blood ketone levels to identify sub clinical verse clinical ketosis, the types of starch used to increase propionate, body condition, to chromium and insulin relationship, Ian covers the lot.
