Making up Milk

To make 100mL of milk: Mix 19g of powder (2½ scoops) with 90ml of warm water.

To make 1 litre of milk: Mix 190g of powder with 900ml of warm water.

Add about half of the water to the powder first and mix to a paste. Then make up with remaining water and mix thoroughly. Water is preboiled 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 larger quantities. Milk can be stored in the fridge for a day or can be frozen for up to 2 weeks. It may be useful to store frozen milk in small portions (e.g. ice cube trays), so that the required daily feed volumes can be easily thawed out. Once thawed out, discard any unused milk, and wash feeding utensils thoroughly.

Feeding Guide

Warm milk to about 30°C and feed using a bottle and teat. An LD Teat is recommended for in-pouch wombats. Feed around 6-8 times per day for joeys with an Age Factor 0.4, gradually reducing this to about 4 times per day once fully-furred. If the joey is showing signs of dehydration (e.g. during hot weather), give extra drinks of water between feeds. Young joeys dehydrate rapidly if not maintained under optimum husbandry conditions. In particular, carers often keep wombats at too high a temperature, which can cause dehydration. Consult your veterinarian or experienced carer for further information about husbandry and feeding of joeys.


Refer to the Common (Bare-nosed) and Southern Hairy-nosed Wombat growth charts. Even within species there may be significant variation in growth rate depending on sex, regional variation and health status. Weigh joeys regularly to verify weight gains and determine the volume of milk to feed. Overfeeding milk can cause diarrhoea so feed the suggested volumes in our tables.

Transition from Wombat 0.4 to Wombat >0.6 formula

Milk transition refers to when a joey is changed from one Wombaroo milk stage to the next. It is important to transition joeys at the correct age to ensure they are getting the proper nutrition for their stage of development. Note that transition is dependent on joey age and not weight, as underweight joeys still need to be transitioned at the correct time. When young wombats start to produce fine fur they are ready to transition onto Wombat Milk Replacer >0.6 formula. Joeys are gradually transitioned over 15 days by mixing decreasing amounts of the 0.4 formula with increasing amounts of the >0.6 formula. This is outlined in the species growth charts.
