PARNUT Entry 61: Reduction of the risk of ketosis (18)
Particular nutritional purpose: Reduction of the risk of ketosis (18)
Species or category of animal: Dairy cows, ewes and goats
Essential nutritional characteristics: — Minimum supply of propane-1,2-diol or propylene glycol: 250 g/day for dairy cows 50 g/day for ewes or goats Or — Minimum supply of propionates (calcium or sodium salts): 110 g/day for dairy cows 22 g/day for ewes or goats Or — Minimum combined supply of propane-1,2-diol and propionates (sodium or calcium salts), as long as: — The combination of propane-1,2-diol and propionates for dairy cows is such that propionates +0,44 x propane-1,2 diol > 110 g/day — The combination of propane-1,2-diol and propionates for ewes or goats is such that propionates +0,44 x propane-1,2 diol > 22 g/day
Recommended length of time: Between three weeks before and six weeks after calving for dairy cows Between six weeks before and three weeks after parturition for ewes and goats
Labelling declarations: — Propane-1,2-diol, if added — Propionates in the form of sodium or calcium salts, if added
Other provisions: 1. Application in the form of bolus is allowed. A bolus may contain up to 20 % iron in an inert, non-bioavailable form, in order to increase its density. 2.
