Turn a critical phase into a healthy investment



Dairy cows and sheep in negative energy balance try to compensate for this by mobilizing their body fat. If the capacity of the liver to metabolize fat is not sufficient, and fat is metabolized into ketones, this results in ketosis. To avoid these problems it is important for the animal to increase its energy intake as soon as possible. Farm-O-San Pro-Keto is a dietetic feed that contains large amounts of glycogenic energy and is able to reduce the risk of ketosis.


Dairy cows: administer 100-125 ml twice daily during the first 3-6 weeks after calving. Adminster 250 ml twice daily where additional energy could support performance. Ewes: administer 30 ml twice daily, through the feed, as topdressing or by an automatic dosing unit in the last 6 weeks before and the first 3 weeks after lambing. In an acute case of ketosis give 70 ml Pro-Keto 2 times a day.


Farm-O-San Pro-Keto contains propylene glycol and glycerine, providing extra energy. Niacin and vitamin B12 improve energy utilization and choline supports proper functioning of the liver. Next to that, Farm-O-San Pro-Keto contains vitamin E and zinc to support resistance.


Pro-Keto contains all essential ingredients for a good start of lactation in dairy cows and to support ewes in the period around lambing. It also includes two flavouring agents, avoiding a negative effect on Dry Matter Intake if Farm-O-San Pro-Keto is included in a TMR.
