Apple Cider Vinegar should be added to feed on a daily basis if possible splitting the required amount between feeds. Horses: 30ml-50ml - Pony: 15ml-30ml - Dog: 2ml - 5ml (1ml = 20 drops) - Poultry: 5ml per litre of drinking water with each water change. This can be increased to 10ml. Cattle: 5ml per 50Kg (110lbs) bodyweight - Sheep & Goats: 5ml-10ml. Animals are individuals so often a lower maintenance amount will be sufficient for long-term use.
