Health Food for Cows


GlucoBoost® is a propriety fermented product available in a dry or liquid form that provides essential glucose precursors for early lactation performance.

Negative Energy Balance and Subclinical Ketosis

Negative Energy Balance and Subclinical Ketosis

Early lactation performance is a challenge on all dairy farms. Dairy cows need to adapt to high milk production, new grouping, new feed and usually a different environment. Negative Energy Balance occurs when the energy expenditure exceeds the energy intake in the ration.

When cows mobilize fat to get to energy neutral ketones can be formed if not enough glucose precursors are provided leading to Sub-Clinical Ketosis (SCK) and Ketosis.

Both Negative Energy Balance and Subclinical Ketosis (SCK) negatively affect reproductive performance1, health2, and immunity3. Ketosis and Sub-Clinical Ketosis are the leading metabolic diseases in dairy cattle4. Incidence of subclinical ketosis can reach up to 75% in commercial dairies5.

What is the cost to the dairy of a cow with high BHBA (greater than 1.1 mm/l)?

Drs. Jessica McArt , Daryl Nydam and Mike Overton (from Cornell and Elanco) estimated in a paper published in 2015 that the average cost per case of Sub-Clinical Ketosis as $289 per cow with the highest cost contributed by the heifers, ($375 / case) due to higher death loss and loss of future production. (McArt, 2015).

*Data in Percentages
Negative Energy Balance and Sub-Clinical Ketosis also cause:
  • Increased risk of DA – 7 times normal6
  • Increased risk of early removal from heard in first 30 Days in Milk7 (DIM)
  • Increase risk of metritis – 3X normal8
  • Reduced Milk production by 7%9
  • Impaired fertility10
For every 1% increase in SCK incidence in the herd, the return over feed (ROF or milk income-feed cost) decreases by $0.015/hd/d.11
