Ketosis risk assessment
Ketosis is a metabolic disease that can cost the dairy farmer a lot of money. It can reduce milk yield by over 500 kilograms of milk per cow per year, while also having an adverse effect on reproduction and welfare for the individual cows. A screening system from FOSS can provide an early warning of ketosis in dairy herds.
Ketosis occurs in dairy cattle when energy output for milk production is too high relative to energy input from feed and uptake from fat deposits. Primary ketosis occurs when too little feed (or too low energy concentration) is offered to the cow. Secondary ketosis occurs if the cow stops eating due to illness while still producing (too much) milk.
In both cases, energy uptake from fat deposits is too high, as is the conversion of fat to glucose in the liver. As a result, acetone and beta-hydroxybutyrate (BHB) are excreted as residues. An indication of levels of the acetone and BHB residues can be provided by the Fourier Transform Infrared (FTIR) technology used in analytical instruments such as the MilkoScan FT+ analyser, allowing screening for ketosis as part of routine milk testing.
The screening gives an indication of possible ketosis, allowing you to single out suspect samples for further investigation. You can give the herd manager a monthly screening of all his cows for ketosis and individual cows can be pointed out for treatment. As ketosis is often a herd problem, a single alert gives the herd manager a timely warning to examine all early lactation cows for problems and to take proactive action as necessary.
