Ketosis is a metabolic disease that occurs as a result of negative energy balance due to a failure to adapt to the energy demands of early lactation.
Hidden ketosis affects around 30% of cows or more1,2 with a large degree of variability between herds.
Whilst clinical ketosis was hardly detected at < 3%, the average herd prevalence of hidden ketosis was 29-58%2. This can be assessed through various means from BHB’s present in the blood through to a simple milk test for freshly calved cows. The higher the level of ketones present, the greater the likelihood of ketosis.
Affected cows may have reduced conception rates,3 longer calving intervals3 and produce significantly less milk.4
They are at risk of developing not just clinical ketosis5 but also other harmful and costly health problems.
Cows with or at risk of developing hidden ketosis are at increased risk of having displaced abomasum,5 retained placenta6, metritis5 and cystic ovaries7 and consequently face a higher culling risk.8 Additionally hidden ketosis means that the cow's immune system is compromised.9
