Milk for Mammals

Milk is the sole source of nutrition for young mammals up until weaning. The composition of milk is very different for each species, depending on the different physiological requirements of the growing young. Click on the links below for our range of species-specific milk replacers, each based on the composition of the natural mother's milk.

    Success in hand-rearing greatly improves if bat pups receive colostrum at birth. Pups that don’t get colostrum from the mother can be fed Impact Colostrum Supplement. Commence feeding Bat Milk Replacer after the initial feeds of colostrum.

    Making up Milk

    To make 20mL of milk: Add 6.5g of powder (1 level scoop) with 15ml of warm water.

    To make 100mL of milk: Add 33g of powder (5 scoops) with 70ml of 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. Wombaroo contains elevated fat levels, so the milk needs to be well mixed to prevent it from separating out. 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. It is useful to make up milk in larger quantities and store it frozen in small portions (eg 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

    Pups should be warmed by hand before feeding. Warm milk to about 35°C. Feed from a dropper or catheter & syringe every 2 hours for the first 3 days, reducing this to every 3 hours by the end of the first week. Stimulate pups to defecate and urinate after each feed. To avoid dehydration during periods of hot weather provide drinks of pre-boiled water between feeds. Always offer drinking water once bat pups become mobile. Consult your veterinarian or specialist wildlife carer for particular advice about caring for microbat pups.

    Growth

    Different species of bats have different growth rates. It is important to weigh pups regularly on an accurate set of scales (to nearest 0.1g) 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.

    Weaning

    When pups are about 3-4 weeks old they may begin to show interest in solid food. To entice them to eat solids offer small mealworms or fly pupae with the heads removed. Once they start to eat solid food continue to increase the solids and reduce the milk in their diet until they are fully weaned at about 6-8 weeks (depending on species). Bats may be encouraged to eat Wombaroo Small Carnivore Food, made up as a moist crumble, supplemented with live insects. Feeder Insects can be supplemented Insect Booster to improve their nutritional quality.
