Mineral deficiency in horses can occur if the concentrate feed is not that great. Does your horse or pony get no or little concentrated feed? When you feed less than 2 kg of concentrate per day for a horse (600 kg) and less than 0.75 kg per day for a pony (300 kg), a deficiency of vitamins and minerals can be. Years of forage research show that hay does not contain enough of these nutrients to keep your horse healthy. Pavo Vital is the perfect solution to this problem!
