Making up Milk - Normal Strength

Mix 1 scoop of powder (7g) with 50ml of preboiled warm water.

To make 1 litre of milk mix 125g of powder (approx. 18 level scoops) with 900ml of  preboiled warm water.

Add half the water to the powder first and mix to a paste. Then add the remaining water and mix thoroughly. Pre-boil the water to ensure that it is sterilised. If the water is too hot it can cause the milk to curdle. If it is too cold then it will be difficult to disperse the powder. An electric whisk can be used for mixing. Milk can be stored in the fridge for a day or can be frozen for up to two weeks. 


Warm milk to about 35°C. Feed from a bottle with teat, Initially feed at normal strength to ensure the milk is tolerated. For improved weight gain, slowly increase the milk to one and a half times normal strength: 1 scoop to 35mL of water (188g of powder plus 850mL of water to make 1 litre).  If the animal develops diarrhoea, reduce the formula strength. To avoid dehydration during periods of hot weather give young a drink of pre-boiled water between feeds. Always offer drinking water once animals become mobile. Consult your veterinarian or breeder for particular advice about caring for your breed of animal.
