Feeding Ewe-2 Warm Milk Lamb Feeder To fill the Ewe-2 with 25 litres of mixed milk, place approx 10 litres of warm water (30°C for younger lambs, 20°C for older lambs) in the inner bucket, add 5kg Volac Lamlac and mix well, then top up with water to a total of 25 litres of mixed milk. Ensure that milk replacer is available on an ad-lib basis and that there is always milk available. On this system, lambs should be drinking approximately 1 litre each per day during the first 7 days and 1.5 - 2 litres each per day up to weaning.
