Proviva Calf Starter is a combination of beneficial bacteria, digestive enzymes and live active yeast that supports the immune system, increases feed breakdown and supports rumen balance and development. It helps protect against disease, allows for calves to be fed high rates of milk with benefits seen in early weaning, labour saving and heifer milk production. Proviva Calf Starter also protects the rumen from digestive upsets leading to nutritional scours and aids in digestion of grass, hay and meal so that the intake of these are increased.
