Reviva: Post-calving rehydration

Directly before and during calving, cows do not eat and drink, but they do lose water and electrolytes, and their blood calcium level goes down. This may turn the animal listless, resulting in a reduction in dry matter intake.
At the start of lactation most cows are in negative energy balance. They try to compensate for this by mobilizing their body fat. This results in a change in their metabolism, which may result in ketosis. It is therefore important for the animal to increase its dry matter intake as soon as possible.


Farm-O-San Reviva is an easily digestible, highly palatable energy drink for freshly calved cows, containing dextrose as one of the energy sources. It quickly rehydrates and replenishes mineral loss in the cow and helps to increase blood calcium levels. Farm-O-San Reviva also contains added vitamins.

Also suitable for sheep.

Pro-Keto: Pre-calving glucose boost

Farm-O-San Pro-Keto is a dietetic feed for high performing dairy cows, based on propylene glycol and glycerine. Farm-O-San Pro-Keto supports the high yielding dairy cow with glycogen energy to reduce the risk of ketosis.
In the two weeks pre-calving, dry matter intake and glucose supply declines and fat mobilization increases. Supplementing the dry cow with a source of glycogen energy can help to boost glucose supply and reduce the risk of ketosis.

Also suitable for sheep.

Pulmosure: Calf respiration

The respiratory tract of calves is challenged the most from the fourth to sixth weeks of life onwards, sometimes up to an age of 10 months. Changing weather conditions, high humidity (> 80%), large temperature differences between day and night and a poor housing climate may have a negative effect on the condition of the airways of calves. Inadequate ventilation, crowded housing, mixing calves from different sources and transportation may result in a decrease in the calves’ respiratory condition.
