Farm-O-San Reviva Bucket 20kg – Energy & Rehydration Support for Freshly Calved Cows
Farm-O-San Reviva is a highly palatable, easily digestible energy drink formulated to support cows immediately after calving. Produced by Farm-O-San, Reviva helps restore energy, fluids and essential minerals at a critical stage of the cow’s production cycle.
During and immediately after calving, cows typically eat and drink very little while losing significant amounts of water, electrolytes and calcium. This can lead to lethargy, reduced feed intake and delayed recovery. At the same time, early lactation places cows under negative energy balance, increasing the risk of metabolic disorders such as ketosis.
Farm-O-San Reviva contains fast-available energy sources, including dextrose, along with added minerals and vitamins to support rapid recovery. When given shortly after calving, it helps rehydrate the cow, replenish mineral losses and support normal blood calcium levels, encouraging earlier activity and improved dry matter intake.
