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. Reviva should be given immediately after calving. It helps the cow to rehydrate rapidly after calving. Reviva also increases the cow’s activity and forage intake. NO VAT on this product
